Damien George 297092a76a esp32/mphalport: Use ets_delay_us for mp_hal_delay_us_fast.
The system provided one is in ROM and is more accurate.
2019-03-12 15:46:44 +11:00
Damien George fcace26d87 esp32/Makefile: Add some missing IDF source files to bootloader and app.
Functions in these files may be needed when certain features are enabled
(eg dual core mode), even if the linker does not give a warning or error
about unresolved symbols.

Andrew Leech 5688c9ba09 stm32/usb: Allow to override USB strings & VID/PID in app and mboot.
The override #define's should go in the board's mpconfigboard.h file.
2019-03-08 23:29:15 +11:00
Andrew Leech 0c60cb1fc4 stm32/qspi: Set pin speed to very-high and allow to config some options.
The default speed of the QSPI interface is 72Mhz whereas the standard AF
pin speed (high) is only rated to 50Mhz, so increase speed to very-high.
2019-03-08 23:17:50 +11:00
Andrew Leech 89ff506513 py: Update and rework build system for including external C modules.
How to use this feature is documented in docs/develop/cmodules.rst.
2019-03-08 22:58:42 +11:00
Andrew Leech cf22f4793c py: Allow registration of modules at their definition.
During make, makemoduledefs.py parses the current builds c files for
MP_REGISTER_MODULE(module_name, obj_module, enabled_define)

These are used to generate a header with the required entries for
"mp_rom_map_elem_t mp_builtin_module_table[]" in py/objmodule.c

Francisco J. Manno f938e70c69 stm32: Add compile-time option to use HSI as clock source.
To use HSI instead of HSE define MICROPY_HW_CLK_USE_HSI as 1 in the board
configuration file.  The default is to use HSE.

HSI has been made the default for the NUCLEO_F401RE board to serve as an
example, and because early revisions of this board need a hardware
modification to get HSE working.

Damien George e61862d063 stm32/boards: Update to use new build config for lwip component. 2019-03-04 23:34:03 +11:00
Damien George 78fe979d7d stm32: Use global lwip build config and support building without lwip. 2019-03-04 23:33:02 +11:00
Damien George 84479569de stm32/boards/STM32F769DISC: Use external QSPI flash to store some code.
This demonstrates how to use external QSPI flash in XIP (execute in place)
mode.  The default configuration has all extmod/ code placed into external
QSPI flash, but other code can easily be put there by modifying the custom
f769_qspi.ld script.
2019-03-04 22:40:15 +11:00
Damien George c8bbf2c170 stm32/Makefile: Allow a board to specify its linker sections for FW.
A board can now use the make variables TEXT0_SECTIONS and TEXT1_SECTIONS to
specify the linker sections that should go in its firmware.  Defaults are
provided which give the existing behaviour.
2019-03-04 22:26:55 +11:00
Damien George f8f2724297 stm32/qspi: Enable sample shift and disable timeout counter.
This makes the QSPI more robust, in particular the timeout counter should
not be used with memory mapped mode (see F7 errata).
2019-03-01 16:15:14 +11:00
Damien George 47e551ba59 cc3200/mpconfigport.h: Disable compiler optimisation of OrderedDict.
This port would rather keep the code size as RAM.
2019-03-01 15:24:29 +11:00
Damien George 8ce22662fe esp8266/modmachine: Call ets_event_poll after waiti in machine.idle.
Because "waiti 0" may have waited for a while (eg 500ms) and the internal
WDT may need to be fed immediately.

Fixes issue #4459.

Damien George 75a35448e1 stm32/boards/NUCLEO_F767ZI: Fix up comments about HCLK computation. 2019-02-26 22:44:27 +11:00
Petr Kracík 21f9329d5d esp32/modnetwork: Fix wifi.isconnected to return False after disconnect.
esp_wifi_connect will return ESP_OK for the normal path of execution which
just means the reconnect is started, not that it is actually reconnected.
In such a case wifi.isconnected() should return False until the
reconnection is complete.  After reconnect a GOT_IP event is called and it
will change wifi_sta_connected back to True.
2019-02-26 00:49:40 +11:00
Damien George 55ff562c70 unix/modffi: Eliminate unused-argument warning when debugging disabled. 2019-02-25 14:53:17 +11:00
Petr Kracík 5801a003f0 esp32/network_lan: Make power arg to constructor optional.
A value of None for this argument is already supported, so the argument can
be made optional.
2019-02-21 23:29:10 +11:00
Petr Kracík 01c1432e32 esp32/modnetwork: Catch and report Ethernet events. 2019-02-21 23:28:51 +11:00
Petr Kracík 7d8c71c222 esp32/network_lan: Add arg to constructor to set clock mode for ETH PHY.
This optional parameter for network.LAN clock_mode can be used for cases
where the clock source is different from the default GPIO0.  Fixes #4502.
2019-02-21 23:28:17 +11:00
Stig Bjørlykke c72391c4ce nrf/pwm: Remove superfluous NULL in machine_hard_pwm_instances.
Remove unneeded NULL entry in machine_hard_pwm_instances[] when not
building for NRF52_SERIES.
2019-02-20 22:52:18 +01:00

Glenn Ruben Bakke ca2bb66127 nrf/bluetooth: Resolve compilation warning in ble_drv.c.
This patch makes sure that the char_data.props is first
assigned a value before other flags are OR'd in.
Resolves compilation warning on possible unitialized variable.
2019-02-20 07:25:51 +01:00
Glenn Ruben Bakke 0c6f5bc529 nrf/bluetooth: Improve advertisment behavior for nrf52 targets.
This patch makes sure that advertisment data is located in
persistent static RAM memory throughout the advertisment.

Also, setting m_adv_handle to predifined
BLE_GAP_ADV_SET_HANDLE_NOT_SET value to indicate first time
usage of the handle. Upon first advertisment configuration
this will be populated with a handle value returned by the
stack (s132/s140).

Glenn Ruben Bakke ee3a01f25c nrf/readme: Update link to nrfjprog download.
After new layout of nordicsemi.com the direct links to
command line tools (nrfjprog) has changed to become dynamic.
This patch removes the old direct links to each specific OS
variant and is replaced with one single link to the download
landing page instead.

Andrew Leech 8ed4a28dae stm32/sdram: Increase GPIO speed for SDRAM interface to "very high".
Currently all usages of mp_hal_pin_config_alt_static() set the pin speed to
"high" (50Mhz).  The SDRAM interface typically runs much faster than this
so should be set to the maximum pin speed.

This commit adds mp_hal_pin_config_alt_static_speed() which allows setting
the pin speed along with the other alternate function details.

Dave Hylands a270cf280b stm32/stm32_it: Fix RTC IRQ handler to handle all EXTI IRQs on F0 MCUs. 2019-02-19 15:17:47 +11:00
Dave Hylands 67b326d97e stm32/extint: Remove unused (and incorrect) EXTI defines. 2019-02-19 15:17:32 +11:00
Dave Hylands 3d17d9b578 stm32/extint: Add non-GPIO EXTI IRQ sources for F0. 2019-02-19 15:17:28 +11:00
Dave Hylands 92fec603d0 stm32/make-stmconst.py: Improve regex to parse more constants.
A few RTC constants weren't being parsed properly due to whitespace
differences, and this patch makes certain whitespace optional.  Changes
made:

- allow for no space between /*!< and EXTI, eg for:
  __IO uint32_t IMR; /*!<EXTI Interrupt mask register, Address offset: 0x00 */

- allow for no space between semicolon and start of comment, eg for:
  __IO uint32_t ALRMASSR;/*!< RTC alarm A sub second register, Address offset: 0x44 */
2019-02-19 15:17:28 +11:00

To make all ports consistent.  Addresses issue #4514.
2019-02-18 23:20:13 +11:00
Damien George c65e5c88b8 stm32/boards/stm32f429.ld: Increase uPy heap size by 64k for F429 MCU.
The F429 has 256k total RAM, with 64k already set aside for flash write
cache, so the uPy heap can be increased this much.
2019-02-18 13:18:59 +11:00
Damien George ed09e13943 esp32/modsocket: Fix usocket.send to accept anything with buffer proto. 2019-02-18 12:38:38 +11:00

Damien George 65b1fefa31 stm32/modmachine: Add ability to pass through user data to mboot. 2019-02-15 15:10:04 +11:00
Damien George 3669198403 stm32/mboot: Add support script which can program mboot and application. 2019-02-15 15:09:59 +11:00
Damien George 3d0c31e60e stm32/mboot: Move some BSS vars to new section that isn't zeroed out.
Zeroing out data on startup takes time and is not necessary for certain
variables.  So provide a declaration for such variables and use it.
2019-02-15 15:09:54 +11:00
Damien George ff04b78ffd stm32/mboot: Add support for loading gzip'd firmware from a filesystem.
This adds support to mboot to load and program application firmware from
a .dfu.gz file on the board's filesystem.  See mboot/README.md for details.
2019-02-15 15:09:48 +11:00
Andrew Leech 4daee31706 stm32/qspi: Use static af functions for pin configuration.
This allows qspi pin configuration to work on any supported platform.
2019-02-14 13:42:08 +11:00
Damien George be4e5b1f87 stm32/mboot/mphalport.h: Include genhdr/pins.h for access to pin names.
So that mboot configuration can use names like pyb_pin_X1.
2019-02-14 13:39:13 +11:00
Damien George f38397ba8d stm32/mboot/Makefile: Generate all pin header files from board pins.csv. 2019-02-14 13:36:32 +11:00

Yonatan Goldschmidt bc4f8b438b extmod/moduwebsocket: Refactor `websocket` to `uwebsocket`.
As mentioned in #4450, `websocket` was experimental with a single intended
user, `webrepl`. Therefore, we'll make this change without a weak
link `websocket` -> `uwebsocket`.
2019-02-14 00:35:45 +11:00
Jolatomme d1acca3c71 stm32/boards/NUCLEO_L476RG: Add support for RNG, DAC and CAN1.
PLLQ is changed to get CAN working, and I2C1 pins are changed to those
prescribed by the board.
2019-02-14 00:28:28 +11:00
Damien George 26a1ae295f stm32/mboot/Makefile: Support specifying BOARD_DIR for custom board. 2019-02-14 00:01:14 +11:00
Yonatan Goldschmidt 66f0afc91d unix/modmachine: Handle repeated /dev/mem open errors.
If opening of /dev/mem has failed an `OSError` is appropriately raised, but
the next time `mem8/16/32` is accessed the invalid file descriptor is used
and the program gets a SIGSEGV.
2019-02-12 15:29:11 +11:00
Mike Causer 812969d615 all: Change PYB message prefix to MPY.
Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between
ports, which is a general goal.  And this change won't break pyboard.py
because that tool only looks for "soft reboot".

Damien George e6d97e8a0b stm32: Move gchelper assembler code to lib/utils for use by other ports. 2019-02-12 14:11:21 +11:00
Damien George e7332b0584 qemu-arm: Rework to run bare-metal on boards with Cortex-M CPUs.
Adds support for 3 Cortex-M boards, selectable via "BOARD" in the Makefile:
- microbit, Cortex-M0 via nRF51822
- netduino2, Cortex-M3 via STM32F205
- mps2-an385, Cortex-M3 via FPGA

netduino2 is the default board because it's supported by older qemu
versions (down to at least 2.5.0).

Damien George 1bcf4afb10 stm32/systick: Make periodic systick callbacks use a cyclic func table.
Instead of checking each callback (currently storage and dma) explicitly
for each SysTick IRQ, use a simple circular function table indexed by the
lower bits of the millisecond tick counter.  This allows callbacks to be
easily enabled/disabled at runtime, and scales well to a large number of
callbacks.
2019-02-08 01:20:13 +11:00
Damien George 5fbda53d3c stm32/systick: Rename sys_tick_XXX functions to systick_XXX. 2019-02-08 01:20:09 +11:00

Damien George 1669e049de stm32/boards/STM32F769DISC: Configure for use with mboot by default.
This is a good board to demonstrate the use of Mboot because it only has a
USB HS port exposed so the native ST DFU mode cannot be used.  With Mboot
this port can be used.
2019-02-07 16:28:01 +11:00
Damien George be1b1835c3 stm32/boards/STM32F769DISC: Support the use of USB HS with external PHY. 2019-02-07 16:26:46 +11:00
Damien George b26046aca2 stm32/modmachine: Make bootloader() enter custom loader if it's enabled.
If a custom bootloader is enabled (eg mboot) then machine.bootloader() will
now enter that loader.  To get the original ST DFU loader pass any argument
to the function, like machine.bootloader(1).

Stig Bjørlykke 98f790b03a nrf/timer: Fix disabling Timer 1 when using soft PWM.
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.

Andrew Leech 67689bfd7e stm32/usb: Add flow control option for USB VCP data received from host.
It's off by default and can be enabled at run-time with:

    pyb.USB_VCP().init(flow=pyb.USB_VCP.RTS)

Ayke van Laethem 1ba962ff57 nrf/uart: Remove unused machine.UART() parameters.
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.
2019-01-31 17:18:23 +11:00
Ayke van Laethem a293fa3d6d nrf/uart: Use formula instead of switch for baudrate calculation.

nrf52: -152
2019-01-31 17:06:59 +11:00
Paul Sokolovsky 2f5d113fad py/warning: Support categories for warnings.
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.

Damien George 86f06d6a87 stm32/sdcard: Don't use SD clock bypass on F7 MCUs.
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.
2019-01-31 12:49:48 +11:00
Damien George e5509a910f stm32/mboot: Add option to autodetect the USB port that DFU uses.
Enable in mpconfigboard.h via #define MBOOT_USB_AUTODETECT_USB (1).
Requires MICROPY_HW_USB_FS and MICROPY_HW_USB_HS to be enabled as well.
2019-01-31 12:05:39 +11:00
Damien George 4bed17e786 stm32/boards/stm32f429_af.csv: Fix typos in UART defs Tx->TX and Rx->RX.
Fixes issue #4445.
2019-01-31 01:02:42 +11:00
Damien George 3ff3e96865 esp8266/modmachine: In lightsleep, only waiti if wifi is turned off.
Otherwise the STA interface can't do DTIM sleeping correctly and power
consumption goes up.
2019-01-31 00:05:00 +11:00
Damien George d5d060ead9 nrf/modmachine: Rename machine.sleep to machine.lightsleep. 2019-01-30 14:15:38 +11:00

Damien George 808dc95ab8 esp8266/modmachine: Implement simple machine.lightsleep function.
Use of "waiti 0" reduces power consumption by about 3mA compared to a
time.sleep_ms call.
2019-01-30 14:05:53 +11:00
Damien George 2911e3554a esp8266/modmachine: Rename machine.sleep to machine.lightsleep.
While keeping machine.sleep as an alias for machine.lightsleep for

Fixes issue #4441.
2019-01-30 12:40:50 +11:00
Damien George 38022ddb2c stm32/main: Make board-defined UART REPL use a static object and buffer.
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.
2019-01-28 22:56:55 +11:00
Damien George f431795caf esp32/boards: Use auto xtal freq config instead of default 40MHz.
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.
2019-01-28 20:42:12 +11:00
Damien George 5d88272342 esp32/Makefile: Make sure that directory exists for sdkconfig.h. 2019-01-28 20:41:13 +11:00
Damien George 9ac9aa989c esp32/machine_timer: Deinit all active timers on soft reset.
Otherwise they will keep triggering the callback and access invalid data on
the heap.
2019-01-28 16:16:03 +11:00
Damien George 3d49b157b8 esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure.
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.
2019-01-28 12:44:03 +11:00
Damien George f59904f799 esp32/Makefile: Put all IDF compenents in .a libs to use IDF ld script.
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.
2019-01-28 12:41:37 +11:00
Damien George e7ab475276 esp32: Don't put py/scheduler.o in iRAM, it's 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.
2019-01-27 16:15:47 +11:00
Damien George 4caf5b2358 stm32/usbdev: Add USB config option for max power drawn by the board.
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.
2019-01-27 14:02:10 +11:00
Damien George 7d8db42d17 stm32/usbdev: Add USB config option for board being self powered.
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).
2019-01-27 13:52:43 +11:00
Damien George c2886868b9 stm32/rtc: Check RTCEN=1 when testing if RTC is already running on boot.
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).
2019-01-27 13:21:31 +11:00
stijn 42863830be py: Add optional support for 2-argument version of built-in next().

2019-01-27 13:01:28 +11:00
Reagan Sanders 51577629b2 cc3200/mods/modussl: Fix ca_certs arg validation in mod_ssl_wrap_socket.
Commit a0d97fe408 changed the argument index
of ca_certs but missed updating one of the references to the new index.
2019-01-27 12:51:34 +11:00
Mikhail Zakharov 18723e9889 unix/mpthreadport: Remove busy wait loop in thread garbage collection.
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.
2019-01-27 12:40:10 +11:00
Mikhail Zakharov 1e7b422226 unix/mpthreadport: Cleanup used memory on thread exit. 2019-01-27 12:39:45 +11:00

This port has been verified to work with these latest changes.
2019-01-25 16:06:13 +11:00
Damien George da72bb6833 esp32/machine_hw_spi: Make HW SPI objects statically allocated.
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.
2019-01-23 23:47:36 +11:00
Damien George d82f344f61 esp32/machine_hw_spi: Use separate DMA channels for HSPI and VSPI.
Otherwise only one of HSPI or VSPI can be used at a time.  Fixes
issue #4068.
2019-01-23 23:40:06 +11:00
Matt Trentini cd52d2c691 esp32/modules/neopixel.py: Change NeoPixel to different default timings.
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.
2019-01-23 14:22:38 +11:00
Damien George 18d3a5df26 esp8266/esp_mphal: Provide mp_hal_pin_od_high_dht so DHT works reliably.
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.
2019-01-22 00:26:04 +11:00
Damien George eb446ec227 esp32/Makefile: Use system provided math library rather than uPy one.
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.
2019-01-17 16:43:20 +11:00
Damien George 90f86a0197 esp32/machine_pin: Add Pin.off() and Pin.on() methods. 2019-01-16 17:33:56 +11:00
Damien George 36808d4e6a esp8266/main: Activate UART(0) on dupterm for REPL before boot.py runs.
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.
2019-01-16 17:24:23 +11:00
Damien George 3431ea7205 stm32/main: Make thread and FS state static and exclude when not needed.
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.
2019-01-11 01:52:17 +11:00
Damien George 5b66c7b712 stm32/wdt: Make singleton WDT object const so it goes in ROM. 2019-01-11 01:51:57 +11:00
Damien George f350b640a0 esp32/modsocket: For socket read only release GIL if socket would block.
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.
2019-01-10 15:46:44 +11:00
Damien George efe0569c26 esp32/mphalport: When tx'ing to REPL only release GIL if many chars sent
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.
2019-01-10 15:43:47 +11:00

Damien George f334816df0 stm32/uart: Make sure user IRQs are handled even with a keyboard intr. 2018-12-30 01:03:22 +11:00
Damien George 7bdbea9a0c stm32/uart: Clear overrun error flag after reading RX data register.
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.
2018-12-30 00:59:16 +11:00
Damien George 0d860fdcd0 stm32/uart: Always enable global UART IRQ handler on init.
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.
2018-12-29 22:44:41 +11:00
Damien George a5f7a3022d stm32/uart: Fix uart_rx_any in case of no buffer to return 0 or 1. 2018-12-29 22:43:35 +11:00
Tobias Badertscher 372e7a4dc6 stm32: Implement UART.irq() method with initial support for RX idle IRQ. 2018-12-29 17:21:37 +11:00
Andrew Leech ce0c581179 stm32/main: Add board config option to enable/disable mounting SD card.
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.
2018-12-22 01:30:47 +11:00
Damien George 0c46419323 windows: Remove remaining traces of old GNU readline support.
GNU readline support for the unix port was removed in
acaa30b604 and in

Damien George bc3f0dddac stm32/uart: Remove HAL's UART_HandleTypeDef from UART object struct.
This UART_HandleTypeDef is quite large (around 70 bytes in RAM needed for

Damien George 485514f57a esp32: Allocate task TCB and stack from system heap not uPy heap.
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.

Paul Sokolovsky 0c18633ea9 unix/modusocket: Finish socket.settimeout() implementation.
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.

Damien George 0f6f86ca49 stm32/usbd_cdc_interface: Refactor USB CDC tx code to not use SOF IRQ.
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).

Christopher Swenson 8c656754aa py/modmath: Add math.factorial, optimised and non-opt implementations.
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.

Damien George 9fb1f18cf4 stm32/sdcard: Fully reset SDMMC periph before calling HAL DMA functions.
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.

Damien George 0941a467e7 stm32: Change flash IRQ priority from 2 to 6 to prevent preemption.
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).

Damien George 47550ef2cd stm32: For MCUs that have PLLSAI allow to set SYSCLK at 2MHz increments.
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.

Paul Sokolovsky fe1ef507ef unix/Makefile: coverage: Explicitly build "axtls" too.
"coverage" build uses different BUILD directory comparing to the normal

build axtls explicitly.

This fixes Travis build in particular.

stijn 3f9d3e120b windows/msvc: Support custom compiler for header generation.
Use overrideable properties instead of hardcoding the use of the
default cl executable used by msvc toolsets. This allows using

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.

Damien George da2d2b6d88 py/mpconfig.h: Introduce MICROPY_DEBUG_PRINTER for debugging output.
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.

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.

Glenn Ruben Bakke 4a323f8b80 nrf/nrfx_config: Move back nrf52832 to use non-EasyDMA SPI
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.

Glenn Ruben Bakke 5925004da3 nrf/modules/machine/spi: Move enable-guard to prevent wrong includes
This patch moves the check of SPI configuration before

After nrfx 1.0.0 a new macro was introduced to do a common

Glenn Ruben Bakke 67fd67f549 nrf/modules/machine/spi: SPIM (EasyDMA) backend for nrf52x
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.

Glenn Ruben Bakke 6e8a605500 nrf/modules/machine/pin: Add support for IRQ on Pin's
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.

Glenn Ruben Bakke 864f671744 nrf: Remove port member from 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.

Ayke van Laethem 2de65dda22 nrf: Make linker scripts more modular.
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).

glennrub 002f7d1ad7 nrf: Replace custom-HAL with nrfx-HAL
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/spi: Updating SPI machine module to use nrfx drivers.

* ports/nrf: Renaming modules/machine/rtc.c/.h to rtcounter.c/.h to not confuse the peripheral with Real-Time Clock:

* 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

Ayke van Laethem 4231d4311f nrf: Fix stack size in ld script and enable MICROPY_STACK_CHECK.
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

[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.
