Don't exclude the Timer instance 1 entry from machine_timer_obj[] when
using soft PWM. The usage is already checked when creating the Timer,
so just create an empty entry.
If needed these parameters can be added back and made functional one at a
time. It's better to explicitly not support them than to silently allow
but ignore them.
Python defines warnings as belonging to categories, where category is a
warning type (descending from exception type). This is useful, as e.g.
allows to disable warnings selectively and provide user-defined warning
types. So, implement this in MicroPython, except that categories are
represented just with strings. However, enough hooks are left to implement
categories differently per-port (e.g. as types), without need to patch each
and every usage.
With clock bypass enabled the attached SD card is clocked at the maximum
48MHz. But some SD cards are unreliable at these rates. Although it's
nice to have high speed transfers it's more important that the transfers
are reliable for all cards. So disable this clock bypass option.
This way the UART REPL does not need the MicroPython heap and exists
outside the MicroPython runtime, allowing characters to still be received
during a soft reset.
Auto-detection of the crystal frequency is convenient and allows for a
single binary for many different boards. But it can be unreliable in
certain situations so in production, for a given board, it's recommended to
configure the correct fixed frequency.
Configuration for the build is now specified using sdkconfig rather than
sdkconfig.h, which allows for much easier configuration with defaults from
the ESP IDF automatically applied. sdkconfig.h is generated using the new
ESP IDF kconfig_new tool written in Python. Custom configuration for a
particular ESP32 board can be specified via the make variable SDKCONFIG.
The esp32.common.ld file is also now generated using the standard ESP IDF
ldgen.py tool.
When the ESP IDF builds a project it puts all separate components into
separate .a library archives. And then the esp32.common.ld linker script
references these .a libraries by explicit name to put certain object files
in iRAM.
This patch does a similar thing for the custom build system used here,
putting all IDF .o's into their respective .a. So a custom linker script
is no longer needed.
ISR's no longer need to be in iRAM, and the ESP IDF provides an option to
specify that they are in iRAM if an application needs lower latency when
handling them. But we don't use this feature for user interrupts: both
timer and gpio ISR routines are registered without the ESP_INTR_FLAG_IRAM
option, and so the scheduling code no longer needs to be in iRAM.
The new compile-time option is MICROPY_HW_USB_MAX_POWER_MA. Set this in
the board configuration file to the maximum current in mA that the board
will draw over USB. The default is 500mA.
The new compile-time option is MICROPY_HW_USB_SELF_POWERED. Set this
option to 1 in the board configuration file to indicate that the USB device
is self powered. This option is disabled by default (previous behaviour).
It can be that LSEON and LSERDY are set yet the RTC is not enabled (this
can happen for example when coming out of the ST DFU mode on an F405 with
the RTC not previously initialised). In such a case the RTC is never
started because the code thinks it's already running. This patch fixes
this case by always checking if RTCEN is set when booting up (and also
testing for a valid RTCSEL value in the case of using an LSE).
One can't use pthread calls in a signal handler because they are not
async-signal-safe (see man signal-safety). Instead, sem_post can be used
to post from within a signal handler and this should be more efficient than
using a busy wait loop, waiting on a volatile variable.
This aligns more closely with the hardware, that there are two, fixed HW
SPI peripherals. And it allows to recreate the HW SPI objects without
error, as well as create them again after a soft reset.
Fixes issue #4103.
In order to suit the more common 800KHz by default (instead of 400KHz), and
also have the same behaviour as the esp8266 port.
Resolves#4396.
Note! This is a breaking change. Anyone that has previously used the
NeoPixel class on an ESP32 board may be affected.
The original behaviour of open-drain-high was to use the open-drain mode of
the GPIO pin, and this seems to make driving a DHT more reliable. See
issue #4233.
The ESP IDF system already provides a math library, and that one is likely
to be better tuned to the Xtensa architecture. The IDF components are also
tested against its own math library, so best not to override it. Using the
system provided library also allows to easily switch to double-precision
floating point by changing MICROPY_FLOAT_IMPL to MICROPY_FLOAT_IMPL_DOUBLE.
So that the user can explicitly deactivate UART(0) if needed. See
issue #4314.
This introduces some risk to "brick" the device, if the user disables the
REPL without providing an alternative REPL (eg WebREPL), or any way to
reenable it. In such a case the device needs to be erased and
reprogrammed. This seems unavoidable, given the desire to have the option
to use the UART for something other than the REPL.
Without the static qualifier these objects will be kept by the linker even
if they are unused. So this patch saves some RAM when these features are
unused by a board.
If there are many short reads to a socket in a row (eg by readline) then
releasing and acquiring the GIL each time will give very poor throughput.
So first poll the socket to see if it has data, and if it does then don't
release the GIL.
Otherwise, if multiple threads are active, printing data to the REPL may be
very slow because in some cases only one character is output per call to
mp_hal_stdout_tx_strn.
On MCUs other than F4 the ORE (overrun error) flag needs to be cleared
independently of clearing RXNE, even though both are wired to trigger the
same RXNE IRQ. In the case that an overrun occurred it's necessary to
explicitly clear the ORE flag or else the RXNE interrupt will keep firing.
Otherwise IRQs may not be enabled for the user UART.irq() handler. In
particular this fixes the user IRQ_RXIDLE interrupt so that it triggers
even when there is no RX buffer.
The new option MICROPY_HW_SDCARD_MOUNT_AT_BOOT can now be defined to 0 in
mpconfigboard.h to allow SD hardware to be enabled but not auto-mounted at
boot. This feature is enabled by default to retain previous behaviour.
Previously, if an SD card is enabled in hardware it is also used to boot
from. While this can be disabled with a SKIPSD file on internal flash,
this wont be available at first boot or if the internal flash gets
corrupted.
Due to new webpages at nordicsemi.com, the download links
for Bluetooth LE stacks were broken.
This patch updates the links to new locations for the current
targets.
This UART_HandleTypeDef is quite large (around 70 bytes in RAM needed for
each UART object) and is not needed: instead the state of the peripheral
held in its registers provides all the required information.
The pin alternate function information is derived from ST's datasheet
https://www.st.com/resource/en/datasheet/stm32l432kc.pdf
In the datasheet, the line 2 of AF4 includes I2C2 but actually the chip
does not have I2C2 so it is removed.
As per the machine.UART documentation, this is used to set the length of
the RX buffer. The legacy read_buf_len argument is retained for backwards
compatibility, with rxbuf overriding it if provided.
Also change the order of printing of flow so it is after stop (so bits,
parity, stop are one after the other), and reduce code size by using
mp_print_str instead of mp_printf where possible.
See issue #1981.
This is necessary for two reasons: 1) FreeRTOS still needs the TCB data
structure even after vPortCleanUpTCB has been called, so this latter hook
function cannot free the TCB, and there is no where else to safely delete
it (this behaviour has changed recently in the ESP IDF); 2) when using
external SPI RAM the uPy heap is in this external memory but the task stack
must be allocated from internal SRAM.
Fixes issue #3904.
We standardized to provide uos.remove() as a more obvious and user-friendly
name. That's what written in the docs. The Unix port implementation
predates this convention, so update it now.
Building axtls gives a lot of warnings with -Wall enabled, and explicitly
disabling all of them cannot be done in a way compatible with gcc and
clang, and likely other compilers. So just use -Wno-all to prevent all of
the extra warnings (in addition to the necessary -Wno-unused-parameter,
-Wno-uninitialized, -Wno-sign-compare and -Wno-old-style-definition).
Fixes issue #4182.
Configurable via MICROPY_MODULE_GETATTR, disabled by default. Among other
things __getattr__ for modules can help to build lazy loading / code
unloading at runtime.
Configurable via MICROPY_PY_BUILTINS_STR_COUNT. Default is enabled.
Disabled for bare-arm, minimal, unix-minimal and zephyr ports. Disabling
it saves 408 bytes on x86.
1. Return correct error code for non-blocking vs timed out socket
(POSIX returns EAGAIN for both, we want ETIMEDOUT in case of timed
out socket). To achieve this, blocking/non-blocking flag is added
to the mp_obj_socket_t, to avoid issuing fcntl() syscall each time
EAGAIN occurs. (mp_obj_socket_t used to be 8 bytes, having some room
in a standard 16-byte alloc block.)
2. Handle socket.settimeout(0) properly - in Python, that means
non-blocking mode, but SO_RCVTIMEO/SO_SNDTIMEO of 0 is infinite
timeout.
3. Overall, make sure that socket.settimeout() call switches blocking
state as expected.
Prior to this commit the USB CDC used the USB start-of-frame (SOF) IRQ to
regularly check if buffered data needed to be sent out to the USB host.
This wasted resources (CPU, power) if no data needed to be sent.
This commit changes how the USB CDC transmits buffered data:
- When new data is first available to send the data is queued immediately
on the USB IN endpoint, ready to be sent as soon as possible.
- Subsequent additions to the buffer (via usbd_cdc_try_tx()) will wait.
- When the low-level USB driver has finished sending out the data queued
in the USB IN endpoint it calls usbd_cdc_tx_ready() which immediately
queues any outstanding data, waiting for the next IN frame.
The benefits on this new approach are:
- SOF IRQ does not need to run continuously so device has a better chance
to sleep for longer, and be more responsive to other IRQs.
- Because SOF IRQ is off, current consumption is reduced by a small amount,
roughly 200uA when USB is connected (measured on PYBv1.0).
- CDC tx throughput (USB IN) on PYBv1.0 is about 2.3 faster (USB OUT is
unchanged).
- When USB is connected, Python code that is executing is slightly faster
because SOF IRQ no longer interrupts continuously.
- On F733 with USB HS, CDC tx throughput is about the same as prior to this
commit.
- On F733 with USB HS, Python code is about 5% faster because of no SOF.
As part of this refactor, the serial port should no longer echo initial
characters when the serial port is first opened (this only used to happen
rarely on USB FS, but on USB HS is was more evident).
For s132 and s140, GAP_ADV_MAX_SIZE was currently set to
BLE_GATT_ATT_MTU_DEFAULT, which is 23. The correct value
should have been 31, but there are no define for this in
the s132/s140 header files as for s110.
Updating define in ble_drv.c to the correct value of 31.
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).
As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot. On boards with SDRAM enabled the heap
has been set to use that.
Add some more POSIX compatibility by adding a d_type field to the
dirent structure and defining corresponding macros so listdir_next
in the unix' port modos.c can use it, end result being uos.ilistdir
now reports the file type.
This will allow to e.g. implement HTTP Digest authentication.
Adds 540 bytes for x86_32, 332 for arm_thumb2 (for Unix port, which already
includes axTLS library).
This commit adds the math.factorial function in two variants:
- squared difference, which is faster than the naive version, relatively
compact, and non-recursive;
- a mildly optimised recursive version, faster than the above one.
There are some more optimisations that could be done, but they tend to take
more code, and more storage space. The recursive version seems like a
sensible compromise.
The new function is disabled by default, and uses the non-optimised version
by default if it is enabled. The options are MICROPY_PY_MATH_FACTORIAL
and MICROPY_OPT_MATH_FACTORIAL.
Configuring clocks is a critical operation and is best to avoid when
possible. If the clocks really need to be reset to the same values then
one can pass in a slightly higher value, eg 168000001 Hz to get 168MHz.
This ensures that on first boot the most optimal settings are used for the
voltage scaling and flash latency (for F7 MCUs).
This commit also provides more fine-grained control for the flash latency
settings.
Power and clock control is low-level functionality and it makes sense to
have it in a dedicated file, at least so it can be reused by other parts of
the code.
On F7s PLLSAI is used as a 48MHz clock source if the main PLL cannot
provide such a frequency, and on L4s PLLSAI1 is always used as a clock
source for the peripherals. This commit makes sure these PLLs are
re-enabled upon waking from stop mode so the peripherals work.
See issues #4022 and #4178 (L4 specific).
Changes made:
- make use of MP_OBJ_TO_PTR and MP_OBJ_FROM_PTR where necessary
- fix shadowing of index variable i, renamed to j
- fix type of above variable to size_t to prevent comparison warning
- fix shadowing of res variable
- use "(void)" instead of "()" for functions that take no arguments
This part is functionally similar to STM32F767xx (they share a datasheet)
so support is generally comparable. When adding board support the
stm32f767_af.csv and stm32f767.ld should be used.
If DTTOIF() macro is not defined, the code refers to MP_S_IFDIR, etc.
symbols defined in extmod/vfs.h, so should include it.
This fixes build for Android.
The HAL DMA functions enable SDMMC interrupts before fully resetting the
peripheral, and this can lead to a DTIMEOUT IRQ during the initialisation
of the DMA transfer, which then clears out the DMA state and leads to the
read/write not working at all. The DTIMEOUT is there from previous SDMMC
DMA transfers, even those that succeeded, and is of duration ~180 seconds,
which is 0xffffffff / 24MHz (default DTIMER value, and clock of
peripheral).
To work around this issue, fully reset the SDMMC peripheral before calling
the HAL SD DMA functions.
Fixes issue #4110.
The flash-IRQ handler is used to flush the storage cache, ie write
outstanding block data from RAM to flash. This is triggered by a timeout,
or by a direct call to flush all storage caches.
Prior to this commit, a timeout could trigger the cache flushing to occur
during the execution of a read/write to external SPI flash storage. In
such a case the storage subsystem would break down.
SPI storage transfers are already protected against USB IRQs, so by
changing the priority of the flash IRQ to that of the USB IRQ (what is
done in this commit) the SPI transfers can be protected against any
timeouts triggering a cache flush (the cache flush would be postponed until
after the transfer finished, but note that in the case of SPI writes the
timeout is rescheduled after the transfer finishes).
The handling of internal flash sync'ing needs to be changed to directly
call flash_bdev_irq_handler() sync may be called with the IRQ priority
already raised (eg when called from a USB MSC IRQ handler).
MCUs that have a PLLSAI can use it to generate a 48MHz clock for USB, SDIO
and RNG peripherals. In such cases the SYSCLK is not restricted to values
that allow the system PLL to generate 48MHz, but can be any frequency.
This patch allows such configurability for F7 MCUs, allowing the SYSCLK to
be set in 2MHz increments via machine.freq(). PLLSAI will only be enabled
if needed, and consumes about 1mA extra. This fine grained control of
frequency is useful to get accurate SPI baudrates, for example.
A recent version of arm-none-eabi-gcc (8.2.0) will warn about unused packed
attributes in USB_WritePacket and USB_ReadPacket. This patch suppresses
such warnings for this file only.
The aim here is to have spi.c contain the low-level SPI driver which is
independent (not fully but close) of MicroPython objects and methods, and
the higher-level bindings are separated out to pyb_spi.c and machine_spi.c.
Among other things, this requires putting bootloader object files in to
their relevant .a archive, so that they can be correctly referenced by the
ESP IDF's linker script.
- Allow configuration by a board of autorefresh number and burst length.
- Increase MPU region size to 8MiB.
- Make SDRAM region cacheable and executable.
"coverage" build uses different BUILD directory comparing to the normal
build. Previously, any build picked up libaxtls.a from normal build's
directory, but that was fixed recently. So, for each build, we must
build axtls explicitly.
This fixes Travis build in particular.
Use overrideable properties instead of hardcoding the use of the
default cl executable used by msvc toolsets. This allows using
arbitrary compiler commands for qstr header generation.
The CLToolExe and CLToolPath properties are used because they are,
even though absent from any official documentation, the de-facto
standard as used by the msvc toolsets themselves.
Requesting a baudrate of X should never configure the peripheral to have a
baudrate greater than X because connected hardware may not be able to
handle higher speeds. This patch makes sure to round the prescaler up so
that the actual baudrate is rounded down.
Prior to this patch, if VBAT was read via ADC.read() or
ADCAll.read_channel(), then it would remain enabled and subsequent reads
of TEMPSENSOR or VREFINT would not work. This patch makes sure that VBAT
is disabled for all cases that it could be read.
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct. This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.
Ports are updated to use the new macro name.
The NRF52 define only covers nrf52832, so update the define checks
to use NRF52_SERIES to cover both nrf52832 and nrf52840.
Fixed machine_hard_pwm_instances table in modules/machine/pwm.c
This enables PWM(0) to PWM(3), RTCounter(2), Timer(3) and Timer(4),
in addition to NFC reset cause, on nrf52840.
When waking from stop mode most of the system is still in the same state as
before entering stop, so only minimal configuration is needed to bring the
system clock back online.
A recent version of arm-none-eabi-gcc (8.2.0) will warn about unused packed
attributes in USB_WritePacket and USB_ReadPacket. This patch suppresses
such warnings for this file only.
Works with pins declared normally in mpconfigboard.h, eg. (pin_XX), as well
as (pyb_pin_XX).
Provides new mp_hal_pin_config_alt_static(pin_obj, mode, pull, fn_type)
function declared in pin_static_af.h to allow configuring pin alternate
functions by name at compile time.
This mechanism will scale to to an arbitrary number of pollable objects, so
long as they implement the MP_STREAM_GET_FILENO ioctl. Since ussl objects
pass through ioctl requests transparently to the underlying socket object,
it will allow ussl sockets to be polled. And a user object with uio.IOBase
as a base could support polling.
The code was dereferencing 0x800 and loading a value from there, trying to
use a literal value (not address) defined in the linker script
(_ram_fs_cache_block_size) which was 0x800.
Adding MICROPY_FATFS as makefile flag in order to explicitly
include oofatfs files to be compiled into the build.
The flag is set to 0 by default. Must be set in addition to
MICROPY_VFS and MICROPY_VFS_FAT in mpconfigport.h.
Temporarly solving the issue of
"differ from the size of original declaration [-Werror=lto-type-mismatch]
until linker is fixed in upcomming release of gcc.
Bug is reported by others, and will be fixed in next version of arm-gcc.
However, this patch makes it possible to use modmusic and modimage
with current compilers.
Alternativly, the code can be compiled with LTO=0, but uses valuable 9K
more on this already squeezed target (microbit).
Support added for s132/s140 v6 in linker scripts and boards.
Support removed for s132 v2/3/5.
Download script updated to fetch new stacks and removed the
non-supported ones.
ble_drv.c updated to only handle s110 v8, and s132/s140 v6.
ubluepy updated to continue scanning after each individual scan
report reported to the module to keep old behaviour of the
Scanner class.
This patch generalize the feather52 target to be a board without
an in-built Bluetooth stack or bootloader giving all flash memory to
micropython code.
This way the feather52 target can run any supported Bluetooth LE
stack the port supports for other nrf52832 targets. Hence, this
make Makefiles/linker scripts and BLE driver support easier
to maintain in the future.
Current adoption on top of nrfx only reads the GPIO->IN register.
In order to read back an output state, nrf_gpio_pin_out_read has
to be called.
This patch concatinate the two read functions such that, if
either IN or OUT register has a value 1 it will return this,
else 0.
Updating lib/nrfx submodule to latest version of master to get
the new GPIO API to read pin direction.
(nrfx: d37b16f2b894b0928395f6f56ca741287a31a244)
Cleaning up use of "pyb" module.
Moving the file to a new folder and updating the
makefile accordingly. New module created called
"board" to take over the functionality of the legacy
"pyb" module.
Updating outdated documentation referring to pyb.Pin,
to now point to machine.Pin.
As EasyDMA variant of SPI(M) might clock out an additional byte
in single byte transactions this patch moves the nrf52832 to
use SPI and not SPIM to get more stable data transactions.
Ref: nrf52832 rev2 errata v1.1, suggested workaround is:
"Use the SPI module (deprecated but still available) or
use the following workaround with SPIM ..."
Current nrfx SPIM driver does not contain this workaround,
and in the meanwhile moving back to SPI fixes the issue.
Also, tabbing the nrfx_config.h a bit to make it more readable.
This patch moves the check of SPI configuration before
including any SPI header files. As targets might disable SPI
support, current code ends up in including SPIM if not SPI
is configured. Hence, this is why the check whether the module is
enabled should be done before including headers.
dfu-gen .PHONY target is run unconditionally as first build
target when included, and might fail if the hex file is not
yet generated.
To prevent this, the dfu-gen and dfu-flash targets are moved
to the main Makefile and only exposed if feather52 is the
defined BOARD.
Update configuration define from
MICROPY_HW_HAS_BUILTIN_FLASH to MICROPY_MBFS.
MICROPY_MBFS will enable the builtin flash as
part of enabling the micro:bit FS.
Clang understands only -fshort-enums, not --short-enums. As
--short-enums isn't even mentioned in the gcc man page, I think this
alias exists more for backwards compatibility.
Removing unused nrf52832_512k_64k_s132_5.0.0.ld.
Adding new linker script s132_5.0.0 following new
linker script scheme.
Updating ble_drv.c to handle de-increment of
outstanding tx packets on hvx for s132 v5.
After nrfx 1.0.0 a new macro was introduced to do a common
hardware timeout. The macro function triggers a counter of
retries or a timeout in us. However, in many cases, like in
nrfx_adc.c the timeout value is set to 0, leading to a infinite
loop in mp_hal_delay_us. This patch prevents this from happening.
Path of error:
nrfx_adc.c -> NRFX_WAIT_FOR -> NRFX_DELAY_US -> mp_hal_delay_us.
This patch also opens up for all arguments to be set as positional
arguments such that an external user of the make_new function can set
provide all parameters as positional arguments.
machine/i2c already uses mp_hal_get_pin_obj which
points to pin_find function in order to locate correct
pin object to use.
The pin_find function was recently updated to also
being able to locate pins based on an integer value,
such that pin number can be used as argument to object
constructors.
This patch modfies and uniforms pin object lookup for
SPI, music and pwm.
Renaming config for enabling random module with hw
random number generator from MICROPY_PY_HW_RNG to
MICROPY_PY_RANDOM_HW_RNG to indicate which module it
is configuring.
Also, disabling the config by default in mpconfigport.h.
Adding the enable of RNG in all board configs.
Moving ifdef in modrandom, which test for the config being
set, earlier in the code. This is to prevent un-necessary
includes if not needed.
Increase the maximum number of queued notifications from 1 to 6. This
massively speeds up the NUS console - especially when printing large
amounts of text. The reason is that multiple transfers can be done in a
single connection event, in ideal cases 6 at a time.
This patch moves all nrf52 targets to use SPIM backend
for SPI which features EasyDMA. The main benefit of doing
this is to utilize the SPIM3 on nrf52840 which is
EasyDMA only peripheral.
This patch ads irq method to the pin object. Handlers
registered in the irq method will be kept as part of the
ROOT_POINTERS.
In order to resolve which pin object is the root of the
IRQ, the pin_find has been extended to also be able to
search up Pin objects based on mp_int_t pin number.
This also implies that the Pin.new API is now also supporting
creation of Pin objects based on the integer value of the
pin instead of old style mandating string name of the Pin.
All boards have been updated to use real pin number from
0-48 instead of pin_Pxx for UART/SPI and music module pins.
UART/SPI/modmusic has also been updated to use pin number
provided directly or look up the Pin object based on the
integer value of the pin (modmusic).
Pin generation has been updated to create a list of pins, where
the board/cpu dicts are now refering to an index in this list
instead of having one const declaration for each pin. This new
const table makes it possible to iterate through all pins generated
in order to locate the correct Pin object.
In order to be able to support GPIO1 port on nrf52840
the port has been removed from the Pin object.
All pins on port1 will now be incrementally on top of
the pin numbers for gpio0. Hence, Pin 1.00 will become
P32, and Pin 1.15 will become P47.
The modification is done to address the new gpio HAL
interface in nrfx, which resolves the port to be
configured base on a multiple of 32.
The patch also affects the existing devices which does
not have a second GPIO port in the way that the
port indication A and B is removed from Pin generation.
This means that the port which was earlier addressed
as PA0 is now P0, and PA31 is P31.
Also, this patch removes the gpio member which earlier
pointed to the perihperal GPIO base address. This is not
needed anymore, hence removed.
With all the variation in chips and boards it's tedious to copy and
redefine linker scripts for every option. Making linker scripts more
modular also opens up more possibilities, like enabling/disabling the
flash file system from the Makefile - or even defining it's size from a
Makefile argument (FS_SIZE=12 for a 12kB filesystem if tight on space).
Summarized this squashed PR replaces the hal/ folder in the port. This has been replaced the official
HAL layer from Nordic Semiconductor; https://github.com/NordicSemiconductor/nrfx.
A Git submodule has been added under lib/nrfx, for the nrfx dependency.
The drivers / modules has been updated to use this new HAL layer; nrfx at v1.0.0.
Also, header files and system files for nrf51/nrf52x chip variants has been deleted from the device/ folder, only keeping back the startup files written in C. All other files are now fetched from nrfx.
3 new header files in the ports/nrf/ folder has been added to configure nrfx (nrfx_config.h), logging (nrfx_log.h) and glue nrfx together with the drivers and modules from micropython (nrfx_glue.h).
The PR has been a joint effort from @aykevl (Ayke van Laethem) and @glennrub.
For reference, the commit log will be kept to get an overview of the changes done:
* ports/nrf: Initial commit for moving hal to Nordic Semiconductor BSD-3 licensed nrfx-hal.
* ports/nrf: Adding nrfx, Nordic Semiconductor BSD-3 hal layer, as git submodule checked out at lib/nrfx.
* ports/nrf/modules/machine/uart: Fixing bug which set hwfc to parity excluded, always resulting in no flow control, hence corrupted output. Also adding an extra loop on uart_tx_char to prevent any tx when any ongoing tx is in progress.
* ports/nrf/i2c: Moving I2C over to nrfx driver.
* ports/nrf/modules/machine/i2c: Alignment. Renaming print function param 'o' to 'self_in'

* ports/nrf: Updating various files after renaming machine module RTC to RTCounter.
* ports/nrf: Renaming RTC to RTCounter in modmachine globals dict table. Also updating object type name to reflect new module name.
* ports/nrf: Fixing leftovers after renaming rtc to rtcounter.
* ports/nrf: Early untested adoption of nrfx_rtc in RTCounter. Untested.
* nrf/modules/machine/i2c: Improve keyword argument handling
* ports/nrf/modules/temp: Updating Temp machine module to use nrfx defined hal nrf_temp.h. Moving logic of BLE stack awareness to machine module.
* ports/nrf/boards/pca10040: Enable machine Temp module.
* nrf/modules/machine/rtcounter: Remove magic constants.
* ports/nrf: Adding base support for nrfx module logging. Adding option to disable logging of UART as it might log its own setup over UART while the peripheral is not yet set up. Logging of UART could make sense if other transport of log is used.
* ports/nrf: updating nrfx_log.h with more correct parenthisis on macro grouping.
* ports/nrf: Updating nrfx logging with configuration to disable logging of UART module. The pattern can be used to turn off other modules as well. However, for now UART is the only module locking itself by logging before the peripheral is configured. Logging is turned off by default, can be enabled in nrfx_config.h by setting NRFX_LOG_ENABLED=1.
* ports/nrf/modules/random: Updating modrandom to use nrfx hal for rng. Not using nrfx-driver for this peripheral as its blocking mode would do the trick on RNG. Moving softdevice aware code from legacy hal to modrandom.c.
* nrf: Enable Peripheral Resource Sharing.
This enables TWI and SPI to be enabled at the same time.
* nrf/Makefile: Define MCU sub variant (e.g. NRF51822/NRF51422)
* nrf: Port TIMER peripheral to nrfx HAL.
* nrf/modules/machine/uart: Optimize UART module
For a nRF51, this results in a size reduction of:
.text: -68 bytes
.data: -56 bytes
* nrf/modules/machine/uart: Don't use magic index numbers.
* nrf/modules/machine/uart: Fix off-by-one error.
For nrf51:
.text: -40 bytes
* nrf/modules/machine/rtcounter: Update for nrfx HAL.
* nrf/modules/machine/i2c: Reduce RAM consumption.
Reductions for the nrf51:
flash: -108 bytes
RAM: -72 bytes
* nrf/mpconfigport: Avoid unnecessary root pointers.
This saves 92 bytes of RAM.
* nrf: Support SoftDevice with nrfx HAL.
* nrf: Add NVMC peripheral (microbitfs) support.
There is no support yet for a SoftDevice.
It also fixes a potentially serious bug in start_index generation.
* nrf/modules/machine/spi: Optimize SPI peripheral.
nrf51:
text: -340 bytes
data: -72 bytes
nrf52:
text: -352 bytes
data: -108 bytes
* nrf/modules/random: Forgot to commit header file.
* nrf: Make nrfx_config.h universal for all boards.
* nrf: Use SoftDevice API for flash access when built for SD
* nrf/drivers/bluetooth: Remove legacy HAL driver includes.
These were not used anymore so can be removed.
* ports/nrf/microbit: Port microbit targets to nrfx HAL
Initial port of microbit modules to use nrfx HAL layer.
Tested display/image and modmusic on micro:bit to verify that
softpwm and ticker for nrf51 is working as expected.
Changing IRQ priority on timer to priority 2, as 1 might collide if
used side by side of SD110 BLE stack.
The patch reserves Timer1 peripheral compile time. This is not ideal
and should be resolved in seperate task.
* nrf/boards/microbit: Remove custom nrfx_config.h from microbit target, adding disablement of timer1 if softpwm is enabled.
* nrf/adc: Update ADC module to use nrfx
* nrf/modules/machine/pwm: Updating machine PWM module to use nrfx HAL driver.
examples/nrf52_pwm.py and examples/nrf52_servo.py tested on pca10040.
* nrf: Removing hal folder and boards nrf5x_hal_conf.h headers.
* nrf/nrfx_glue: Adding direct NVIC access for S110 BLE stack
If SoftDevice s110 has not yet been initialized, the IRQ will not be forwarded to
the application using the sd_nvic* function calls. Hence, direct access to cmsi
nvic functions are used instead if SoftDevice is not enabled.
* nrf/drivers/ticker: Setting IRQ priority 3 on Timer1
SoftDevice fails to initilize if Timer1 has been configured to priority
level 2 before enabling the SD. The timer is set to priority 1, higher than BLE
stack in order to provide better quality of music rendering when used with the
music module. This might be too high, time will show.
* nrf/examples: Updating ubluepy_temp after moving RTCounter to nrfx.
* nrf: delete duplicate files from device folder which can be located in nrfx/mdk.
* nrf/Makefile: Fetch system files from nrfx.
Testing on each device sub-variant to figure out which system file to
use. Reason for this is that nrf52.c is actually defining nrf52832.
Removing NRF_DEFINES parameter setting the device in use into the
same sub-variant test, as NRF52 is unique to nrf52832 when using nrfx.
Without this exclusion of -DNRF52 in compilation for nrf52840, the
device will be interpreted as a nrf52, hence nrf52832.
Also, changing name on variable SRC_NRF_HAL to SRC_NRFX_HAL to
explicitly tell the origin of the file.
* nrf: Updating device #ifdefs to be more open to non-nrf51 targets.
* nrf/modules/machine/uart: Removing second instance of UART for nrf52840 as it only has one non-DMA variant.
* nrf/device: Removing system files as these are now used from nrfx/mdk
* nrf: Moving startup files in device one level up as there is no need for deep hierarchy.
* nrf: Use NRF52_SERIES defined in nrfx/mdk/nrf.h as define value when testing for both nrf52(832) and nrf52840 variants.
* nrf/modules/machine/uart: Enable UART RX by default
Enable rx by default after intiialization of the peripheral.
Else, the nrfx driver will re-enable rx for each byte read
on uart REPL, clearing the EVENT_RXDRDY before second byte,
which again will make second byte get lost and read will get stuck.
This happens if the bytes are transmitted nrf(51) while still
processing the previous byte. Not seen on nrf52, but should
also become an issue at higher speeds.
This patch sets rx to always be enabled. Hence, not clearing the event
between read bytes, and it will be able to detect next byte recieved
upon finishing the first.
* nrf/modules/machine/timer: Fixing defines excluding Timer1 if ticker/softpwm is used.
* nrf: Switching import form mpconfigboard.h to mpconfigport.h in nrfx_config.h as mpconfigboard.h might define default values for defines not set by board specific header.
* nrf/modules/machine/i2c: nrfx integration fixes
Increasing speed to 400K.
Returning Address NACK's as MP error code; MP_ENODEV.
Returning MP_ETIMEOUT on all other error codes from TWI nrfx driver
except the ANACK.
Enabling and disabling the TWI peripheral before and after each transaction.
* nrf/examples: Updating ssd1306_mod.py to split framebuffer transfer into multiple chunks
* nrf/modules/machine/i2c: Return MP_EIO error if Data NACK occurs.
* nrf: Addressing review comments.
* nrf: Updating git submodule and users to nrfx v1.0.0.
* nrf/modules/machine/adc: Update adc module to follow v1.0.0 nrfx API.
* nrf/modules/machine/spi: Implement init and deinit functions
Extending SPI objects with a config member such that
configuration can be kept between new() and init().
Moving initialization done in new() to common init
function shared between the module functions.
If SPI is already configured, the SPI peripheral will
be uninitialized before initalized again.
Adding logic to handle initialization of polarity and
phase. As well, updating default speed to 1M from 500K.
* nrf/modules/machine: Removing unused nrfx includes in machine module header files
When compiling for microbit with LTO=0, a compiler error occurs due to
'ms' variable in the microbit_sleep function has not been initialized.
This patch initialize the variable to 0.
The nrf51x22_256k_16k_s110_8.0.0.ld had a stack size of only 1kB, which
is way too low. Additionally, the indicated _minimum_stack_size (set at
2kB for that chip) isn't respected.
This commit sets the heap end based on the stack size (heap end = RAM
end - stack size) making it much easier to configure.
Additionally, the stack/heap size of nrf52 chips has been set to a more
sane value of 8kB.
Leave it enabled by default on all targets.
This is only possible when using UART-over-BLE (NUS) instead of the
default hardware peripheral. The flash area saved is quite substantial
(about 2.2KB) so this is useful for custom builds that do not need UART.
Feather52 target which is using SD s132 v.2.0.1 cannot compile
due to variable containing RAM start address is not used.
This patch enables the correct sd_ble_enable variant for this SD.
Similar commit to this one:
6e56e6269f
When .text + .data oveflow available flash, the linker may not show an
error. This change makes sure .data is included in the size calculation.
This frees 128 bytes of .bss RAM on the nRF51, at the cost of possibly
more expensive GC cycles. Leave it as-is on the nRF52 as that chip has a
lot more RAM.
This is also done in the micro:bit:

* ports/nrf/boards: Adding linker script for nrf52832 using BLE stack s132 v.5.0.0.
* ports/nrf/drivers/bluetooth: Updating makefile to add BLE_API_VERSION=4 if s132 v5.0.0 is used.
* ports/nrf/drivers/bluetooth: Updating BLE stack download script to also download S132 v5.0.0.
* ports/nrf/drivers/bluetooth: Updating ble_drv.c to handle BLE_API_VERSION=4 (s132 v5.0.0).
* ports/nrf/boards: Updating linker script for nrf52832 with s132 v.5.0.0 bluetooth stack.
* ports/nrf/drivers/bluetooth: Removing commented out code in ble_drv.c
* ports/nrf/drivers/bluetooth: Updating define of GATT_MTU_SIZE_DEFAULT for SD132v5 to be defined using the new name defined in the SD headers in a more generic way.
* ports/nrf/drivers/bluetooth: Cleaning up use of BLE_API_VERSION in the ble_drv.c. Also considering s140v6 API, so not all has been changed to >= if API version 3 and 4 in combo is used. New s140v6 will differ on these, and add a new API not compatible with the API for 3 and 4.
- Rename microbit_module_init to board_module_init0 which is the generic
board module init function.
- Add low priority callback registration of display tick handler in the
module init function.
- Rename init function to ticker_init0.
- Implement ticker_register_low_pri_callback (recycle of unused
set_low_priority_callback function which was unimplemented).
- Add support for registering 2 low pri callbacks. For now, one intended
for microbit display, and one for modmusic.
* ports/nrf: Add micro:bit filesystem.
This filesystem has been copied from BBC micro:bit sources [1] and
modified to work with the nRF5x port.
[1]: https://github.com/bbcmicrobit/micropython/blob/master/source/microbit/filesystem.c
* ports/nrf/modules/uos: Make listdir() and ilistdir() consistent.
This removes the optional direcotry paramter from ilistdir(). This is
not consistent with VFS, but makes more sense when using only the
microbit filesystem.
Saves about 100 bytes.
* ports/nrf/modules/uos: Add code size comment.
* Remove FLASH_ISR and merge .isr_vector into FLASH_TEXT. This saves
some code space, especially on nRF52 devices.
* Reserve space for nonvolatile storage of data. This is the place for
a filesystem (to be added).

nrf/modules/random: Backport of microbit random number generator module
Backport of micro:bit random module.
Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.
Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.
Glenn Ruben Bakke <glennbakke@gmail.com>
nrf/hal/rng: Adding HAL driver for accessing RNG peripheral
The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.
Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).

nrf: Add support for floating point on nrf52 targets.
Duplicating pattern for detecting location of libm, libc and libgcc
from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
and adding libs into the compile. For nrf51 targets it is still set to
NONE as code grows to much (about 30k).
Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

nrf5/modules/music: Correct parameter checking of pin argument to deside whether to use MUSIC_PIN define or throw an error. If MUSIC_PIN define is configured the pin argument to music module play() can be elided.
nrf5/modules/machine: Update timer init to set default IRQ priority before initializing Timer instance.
nrf5/hal/timer: Update timer hal to use value provided in init to configure the irq_priority.
nrf5/modules/machine: Reserving timer0 instance for bluetooth if compiled in. Leaving timer1 and timer2 for application. Note that music module soft-pwm will also occupy timer1 if enabled.
nrf5/modules/machine: Updating timer module to use new hal. Adding new parameters to the init to set period, mode and callback.
nrf5/hal/timer: Implementing hal_timer to 1us prescaler. Multiplier inside to get to millisecond resolution. Callback must be registered before starting a timer.

Matt Trentini <matt.trentini@gmail.com>
Adding a README for the nRF5 port
Glenn Ruben Bakke <glennbakke@gmail.com>
nrf5/examples: Updating documentation in SDCard module example. Correcting typo and adding SD card wireing documentation for direct SPI connection.
nrf5/modules/pin: Adding on() and off() methods to Pin object to be forward compatible with upstream master. Legacy high() and low() methods are kept.
nrf5/modules/spi: Remove pyb abstraction from SPI module, as there was a bug in transfer of bytes due to casting errors. The update removes the pyb_spi_obj_t wrapper going directly on the machine_hard_spi_obj_t as base for machine SPI objects. SDCard mounting is also tested.
nrf5/drivers/bluetooth: Enable ubluepy central by default if running nrf52/s132 bluetooth stack. Maturity of the module is pretty OK now.
nrf5/boards/feather52: Updating pins.csv for the feather52 board.
nrf5/boards/feather52: Updating LED pull to low.
nrf5/boards/feather52: Update SPI pinout.
nrf5/main: Move initializaton of modmusic to the module itself. Upon init of the module, the hardware, pwm and ticker will be started. Could be moved back to main if pwm or ticker should be shared among more modules and have to be initialized more global.
nrf5/modules/machine/timer: If timer is used in combination with SOFT_PWM (implicitly use of ticker.c) guard the Timer1 instance from being instantiated trough python timer module. Also disable implementation of the HAL IRQ handler which is for now explicitly implemented in ticker.c for Timer1.
nrf5/modules/music: Update ticker and modmusic to share global ticks counter as a volatile variable. Use Timer1 hardware peripheral instead of instance 0. Timer0 is not free if used in combination with a bluetooth stack. Update IRQ priority to levels that are compatible in use with a bluetooth stack for both nrf51 and nrf52. Apply nrf51 PAN fixes for Timer1 instead of original Timer0.
nrf5/drivers/bluetooth: Updating bluetooth driver to initialize nrf_nvic_state_t struct during declaration of the global variable instead of explicit memset.
nrf5/hal/irq: Adding wrappers for handling nvic calls when Bluetooth LE stack is enabled.
nrf5/modules/machine: Updating IRQ levels in SPI with IRQ priorities compatible with Bluetooth stacks.
nrf5/device: Remove old startup files in asm, which has now been replaced with c-implementation.
nrf5: Update Makefile to add c-implementation of startup scripts instead of the .s files.
nrf5/device: Adding startup files in .c to replace current asm versions.
nrf5/examples: Tuning Bluetooth LE example controller python script after testing out the example live. Motor speed of 100 was not enought to lift the airplane. Also turning was hard without setting higher angle values. The new values are just guessed values. However, the flying experience was good.
nrf5/hal/irq: Adding include of nrf_nvic.h if s132 bluetooth stack is used to resolve IRQ function wrappers on newer bluetooth stacks.
nrf5/drivers/ticker: Removing unused code.
nrf5/examples: Adding music example. Only working if bluetooth stack is not enabled.
nrf5/boards/microbit: Disable music and softPWM as there are some issues with the ticker.
nrf5: Adding -fstack-usage flag to gcc CFLAGS to be able to trace stack usage on modules.
nrf5/drivers/ticker: Removing LowPriority callback from nrf51 as there is only one SoftwareIRQ free if bluetooth stack is enabled. Also setting new IRQ priority on SlowTicker to 3 instead of 2, to interleave with bluetooth stack if needed. Updating all NVIC calls to use hal_irq.h defined static inlines instead of direct access.
nrf5/hal/irq: Adding IRQ wrappers if Bluetooth Stack is present.
nrf5: Facilitate option to configure away the modble if needed. Enabled if MICROPY_PY_BLE config is enabled in bluetooth_conf.h.
nrf5/boards/microbit: Enable music module by default. However, timer and rtc module has to be disabled. Bluetooth support broken. Optimization needed.
nrf5/modules/machine: Quickfix. Update timer object to not allow instanciation of Timer(0) if SOFT_PWM is enabled by board.
nrf5/hal/timer: Quickfix. Disable IRQ handler if SOFT_PWM is configured to be enabled. Ticker driver has in current driver a seperate IRQ handler for this timer instance.
nrf5/drivers/ticker: Add compile config guard in ticker.c to only include the driver if SOFT_PWM is configured in by board.
nrf5/drivers/softpwm: Renaming pwm_init to softpwm_init to not collide on symbol name with pwm_init in nrf52 machine PWM object.
nrf5: Add modmusic QSTR definition of notes to qstrdefsport.h.
nrf5: Update Makefile to include ticker.c and renamed softpwm. Updating also include paths to include modules/music and drivers/.
nrf5: Adding include of modmusic.h in main.c.
nrf5: Call microbit_music_init0() if enabled in main.c.
nrf5/modules/music: Expose public init function for music module.
nrf5/modules/music: Update modmusic to use updated includes. Add extern ticks. Add function which implements initialization of pwm and ticker, register ticker callback, and start the pwm and ticker. This corresponds to microbit port main.cpp init.
nrf5/drivers/softpwm: Enable use of ticker in softpwm driver.
nrf5/drivers/ticker: Adding ticker.c/.h from microbit port.
nrf5/drivers/pwm: Renaming pwm.c/.h to softpwm.c/.h
nrf5/drivers/pwm: Expose pwm_init() as public function.
nrf5/modules/ubluepy: Making peripheral conn_handle volatile. Upon connection event, the variable is accessed in thread mode. However, the main-loop is blocking on conn_handle != 0xFFFF. If this is not volatile, optimized code will not exit the loop.
nrf5/drivers/bluetooth: As callback functions are in most usecases are set to NULL upon last event to get public API function out of blocking mode, these function pointers has to be set as volatile, as they are updated to NULL in interrupt context, but read in blocking main-thread.
nrf5/examples: Fixing overlapping function names and variable names inside the object. Also removing some print statements. Tuning max angle from -7/7 to -25/25.

init
Date of "init" commit: Wed Jun 22 22:34:11 2016 +0200
The period of the timer can now be specified using the "period" and
"tick_hz" args. The period in seconds will be: period/tick_hz. tick_hz
defaults to 1000, so if period is specified on its own then it will be in
units of milliseconds.
machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument. The period of
the timer in seconds is: period/tick_hz.
For backwards compatibility tick_hz defaults to 1000. If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000. The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.
An additional freq argument has been added to allow frequencies to be
specified directly in Hertz. This supports floating point values when
available.
Using direct register control as specified by ESP-IDF in
components/esp32/test/test_tsens.c. Temperature doesn't represent any
particular unit, isn't calibrated and will vary from device to device.
Prior to this patch, get_fattime() was calling a HAL RTC function with the
HW instance pointer as null because rtc_init_start() was never called.
Also marked it as a weak function, to allow a board to override it.
With this and previous patches the stm32 port can now be compiled using
object representation D (nan boxing). Note that native code and frozen mpy
files with float constants are currently not supported with this object
representation.
Printing debugging info by defining MICROPY_DEBUG_VERBOSE expects
a definition of the DEBUG_printf function which is readily available
in printf.c so include that file in the build. Before this patch
one would have to manually provide such definition which is tedious.
For the msvc port disable MICROPY_USE_INTERNAL_PRINTF though: the
linker provides no (easy) way to replace printf with the custom
version as defined in printf.c.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.
This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.
This patch allows scripts to have more control over the software WDT. If
an instance of machine.WDT is created then the underlying OS is prevented
from feeding the software WDT, and it is up to the user script to feed it
instead via WDT.feed(). The timeout for this WDT is currently fixed and
will be between 1.6 and 3.2 seconds.
A flash erase/write takes a while and during that time tasks may be
scheduled via an IRQ. To prevent overflow of the task queue (and loss of
tasks) call ets_loop_iter() before and after slow flash operations.
Note: if a task is posted to a full queue while a flash operation is in
progress then this leads to a fault when trying to print out the error
message that the queue is full. This patch doesn't try to fix this
particular issue, it just prevents it from happening in the first place.
This function may be called from a UART IRQ, which may interrupt the system
when it is erasing/reading/writing flash. In such a case all code
executing from the IRQ must be in iRAM (because the SPI flash is busy), so
put mp_keyboard_interrupt in iRAM so ctrl-C can be caught during flash
access.
This patch also takes get_fattime out of iRAM and puts it in iROM to make
space for mp_keyboard_interrupt. There's no real need to have get_fattime
in iRAM because it calls other functions in iROM.
Fixes issue #3897.
Target RAM size is no longer set using Kconfig options, but instead using
DTS (device tree config). Fortunately, the default is now set to a high
value, so we don't need to use DTS fixup.
CONFIG_NET_NBUF_RX_COUNT no longer exists in Zephyr, for a while. That
means we build with the default RX buf count for a while too, and it works,
so just remove it (instead of switching to what it was renamed to,
CONFIG_NET_PKT_RX_COUNT).
The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.
The naming of the module follows (u)hashlib pattern.
At the bare minimum, this module is expected to provide:
* AES128, ECB (i.e. "null") mode, encrypt only
Implementation in this commit is based on axTLS routines, and implements
following:
* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt
Prior to this patch, if both USB FS and HS were enabled via the
configuration file then code was included to handle both of their IRQs.
But mboot only supports listening on a single USB peripheral, so this patch
excludes the code for the USB that is not used.
Only one of pcd_fs_handle/pcd_hs_handle is ever initialised, so if both of
these USB peripherals are enabled then one of these if-statements will
access invalid memory pointed to by an uninitialised Instance. This patch
fixes this bug by explicitly referencing the peripheral struct.
