Damien George 580fd636c0 nrf/drivers: Use mp_raise_msg where appropriate, and shorten exc msgs.
If the exception doesn't need printf-style formatting then calling
mp_raise_msg is more efficient.  Also shorten exception messages to match
style in core and other ports.

Damien George ce40abcf21 stm32/usbd_cdc_interface: Remove "interrupt_char != -1" check.
It's not needed.  The C integer implicit promotion rules mean that the
uint8_t of the incoming character is promoted to a (signed) int, matching
the type of interrupt_char.  Thus the uint8_t incoming character can never
be equal to -1 (the value of interrupt_char that indicate that interruption
is disabled).

Damien George 046ae80bdf unix, windows: Use mp_keyboard_interrupt instead of custom code.
The mp_keyboard_interrupt() function does exactly what is needed here, and
using it gets ctrl-C working when MICROPY_ENABLE_SCHEDULER is enabled on
these ports (and MICROPY_ASYNC_KBD_INTR is disabled).
2020-02-07 16:08:33 +11:00
Damien George abe2caf6df py/scheduler: Move clearing of kbd traceback to mp_keyboard_interrupt.
This is a more logical place to clear the KeyboardInterrupt traceback,
right before it is set as a pending exception.  The clearing is also
optimised from a function call to a simple store of NULL.

Damien George f4641b2378 esp32/uart: Use core-provided mp_keyboard_interrupt, placed in IRAM. 2020-02-07 16:08:31 +11:00
Damien George 8d0421c3cf esp8266: Put mp_keyboard_interrupt in IRAM.
It was originally in IRAM due to the linker script specification, but
since the function moved from lib/utils/interrupt_char.c to py/scheduler.c
it needs to be put back in IRAM.
2020-02-07 16:08:31 +11:00
Damien George eaf30c516a tests/unix: Add coverage tests for kbd-intr and scheduler. 2020-02-07 16:08:29 +11:00
Damien George 9efb36bfa6 py/scheduler: Move mp_keyboard_interrupt from lib/utils to py core.
This function is tightly coupled to the state and behaviour of the
scheduler, and is a core part of the runtime: to schedule a pending
exception.  So move it there.
2020-02-07 16:08:26 +11:00
Damien George 5a91cd9ff3 lib/utils/pyexec: Handle pending exceptions after disabling kbd intrs.
Pending exceptions would otherwise be handled later on where there may not
be an NLR handler in place.

A similar fix is also made to the unix port's REPL handler.

Fixes issues #4921 and #5488.
2020-02-07 16:08:26 +11:00
Damien George 98a3911c43 py/scheduler: Add "raise_exc" argument to mp_handle_pending.
Previous behaviour is when this argument is set to "true", in which case
the function will raise any pending exception.  Setting it to "false" will
cancel any pending exception.

Maureen Helm 7a5752a748 zephyr: Enable littlefs.
Enables the littlefs (v1 and v2) filesystems in the zephyr port.

Example usage with the internal flash on the reel_board or the
rv32m1_vega_ri5cy board:

import os
from zephyr import FlashArea
bdev = FlashArea(FlashArea.STORAGE, 4096)
os.VfsLfs2.mkfs(bdev)
os.mount(bdev, '/flash')
with open('/flash/hello.txt','w') as f:
    f.write('Hello world')
print(open('/flash/hello.txt').read())

Things get a little trickier with the frdm_k64f due to the micropython
application spilling into the default flash storage partition defined
for this board. The zephyr build system doesn't enforce the flash
partitioning when mcuboot is not enabled (which it is not for
micropython). For now we can demonstrate that the littlefs filesystem
works on frdm_k64f by constructing the FlashArea block device on the
mcuboot scratch partition instead of the storage partition. Do this by
replacing the FlashArea.STORAGE constant above with the value 4.
2020-02-07 11:24:06 +11:00
Maureen Helm 86a66960f9 zephyr: Implement block device protocol via zephyr flash map api.
Introduces a new zephyr.FlashArea class that uses the zephyr flash map
api to implement the uos.AbstractBlockDev protocol. The flash driver is
enabled on the frdm_k64f board, reel_board, and rv32m1_vega_ri5cy board.

The standard and extended block device protocols are both supported,
therefore this class can be used with file systems like littlefs which
require the extended interface.
2020-02-07 11:24:06 +11:00
Maureen Helm 2d7ec8e704 zephyr: Enable fatfs.
Enables the fatfs filesystem in the zephyr port.

Example usage with an SD card on the mimxrt1050_evk board:

import zephyr, os
bdev = zephyr.DiskAccess('SDHC')
os.VfsFat.mkfs(bdev)
os.mount(bdev, '/sd')
with open('/sd/hello.txt','w') as f:
    f.write('Hello world')
print(open('/sd/hello.txt').read())
2020-02-07 11:24:06 +11:00
Maureen Helm a0440b01ea zephyr: Enable virtual file system and uos module.
Enables the virtual file system and uos module in the zephyr port.
No concrete file system implementations are enabled yet.
2020-02-07 11:24:06 +11:00
Maureen Helm cc19cf2549 zephyr: Implement block device protocol via zephyr disk access api.
Introduces a new zephyr.DiskAccess class that uses the zephyr disk
access api to implement the uos.AbstractBlockDev protocol. This can be
used with any type of zephyr disk access driver, which currently
includes SDHC, RAM, and FLASH implementations. The SDHC driver is
enabled on the mimxrt1050_evk board.

Only the standard block device protocol (without the offset parameter)
can be supported with the zephyr disk access api, therefore this class
cannot be used with file systems like littlefs which require the
extended interface. In the future it may be possible to implement the
extended interface in a new class using the zephyr flash api.

Damien George d6a1e45caa stm32/usbd_conf: Allow boards to configure USB HS ULPI NXT/DIR pins. 2020-02-04 23:15:55 +11:00
Andrew Leech ff9a61b5a8 stm32/sdram: Expose the result of sdram startup test in stm32_main.
This means boards can choose to only use it for gc heap if the test passes.

David Lechner f1b6e6bb15 unix/modos: Implement putenv and unsetenv to complement getenv.
CPython also has os.environ, which should be used instead of os.getenv()
due to caching in the os.environ mapping.  But for MicroPython it makes
sense to only implement the basic underlying methods, ie getenv/putenv/
unsetenv.
2020-02-04 17:54:31 +11:00
David Lechner 83439e38fc unix/main: Add command-line -h option for printing help text.
This adds a -h option to print the usage help text and adds a new, shorter
error message that is printed when invalid arguments are given.  This
behaviour follows CPython (and other tools) more closely.
2020-02-04 17:54:31 +11:00
David Lechner 5a63bc5a44 unix/main: Add #if guard around -v option usage and document -i/-m opts.
This commit modifies the usage() function to only print the -v option help
text when MICROPY_DEBUG_PRINTERS is enabled.  The -v option requires this
build option to be enabled for it to have any effect.

The usage text is also modified to show the -i and -m options, and also
show that running a command, module or file are mutually exclusive.
2020-02-04 17:53:35 +11:00
David Lechner 122baa6787 unix/main: Add support for MICROPYINSPECT environment variable.
This adds support for a MICROPYINSPECT environment variable that works
exactly like PYTHONINSPECT; per CPython docs:

    If this is set to a non-empty string it is equivalent to specifying the
    -i option.

    This variable can also be modified by Python code using os.environ to
    force inspect mode on program termination.
2020-02-04 17:52:58 +11:00
Maureen Helm bc3ce86a5a zephyr: Remove reference to syscall_macros_h_target.
Zephyr removed the build target syscall_macros_h_target in commit
f4adf107f31674eb20881531900ff092cc40c07f.  Removes reference from
MicroPython to fix build errors in the zephyr port.

This change is not compatible with zephyr v2.1 or earlier.  It will be
compatible with Zephyr v2.2 when released.
2020-02-04 17:10:24 +11:00
Maureen Helm a7663b862e zephyr: Replace deprecated time conversion macro.
The SYS_CLOCK_HW_CYCLES_TO_NS macro was deprecated in zephyr commit
8892406c1de21bd5de5877f39099e3663a5f3af1.  This commit updates MicroPython
to use the new k_cyc_to_ns_floor64 api and fix build warnings in the zephyr
port.

This change is compatible with Zephyr v2.1 and later.
2020-02-04 17:09:59 +11:00
Maureen Helm c25e12d0dd zephyr: Update include paths for Zephyr v2.0.
Zephyr restructured its includes in v2.0 and removed compatibility shims
after two releases in commit 1342dadc365ee22199e51779185899ddf7478686.
Updates include paths in MicroPython accordingly to fix build errors in
the zephyr port.

These changes are compatible with Zephyr v2.0 and later.

David Lechner 4ab8bee82f unix/main: Print usage and NLR errors to stderr instead of stdout.
When stdout is redirected it is useful to have errors printed to stderr
instead of being redirected.

mp_stderr_print() can't be used in these two instances since the
MicroPython runtime is not running so we use fprintf(stderr) instead.

caochaowu 61f64c78a6 nrf/boards/common.ld: Add ENTRY(Reset_Handler) in linker script.
It's not strictly needed but can be helpful when using a debugger.

Damien George e3ff52863b esp8266/modules/ntptime.py: Add comment about configuring NTP host.
The ability to change the host is a frequently requested feature, so
explicitly document how it can be achieved using the existing code.

Damien George af88e70414 stm32/powerctrl: Reenable PLL3 on H7 MCUs when waking from stop mode.
So that USB can work.
2020-01-31 23:25:18 +11:00
Damien George 2c8c2b935e stm32/powerctrl: Improve support for changing system freq on H7 MCUs.
This commit improves pllvalues.py to generate PLL values for H7 MCUs that
are valid (VCO in and out are in range) and extend for the entire range of
SYSCLK values up to 400MHz (up to 480MHz is currently unsupported).
2020-01-31 23:25:18 +11:00
Damien George 03b73ce329 stm32/stm32_it: Don't call __HAL_USB_HS_EXTI_CLEAR_FLAG on H7 MCUs.
It doesn't exist on these MCUs.
2020-01-31 23:25:18 +11:00
Damien George 257b17ec10 stm32/sdio: Add support for H7 MCUs.
The cyw43 driver on stm32 will now work with H7 MCUs.

Damien George 31ba06ce84 stm32/boards/stm32f746_af.csv: Add ADC alt functions to correct pins. 2020-01-30 16:31:11 +11:00
Damien George 68db7e01d8 stm32/powerctrl: Enable overdrive on F7 when waking from stop mode.
Because if the SYSCLK is set to 180MHz or higher it will require this to be
on already.

Damien George 29b84ea798 stm32/powerctrl: Disable HSI if not needed to save a bit of power. 2020-01-30 16:29:45 +11:00
Damien George 96a4435be1 stm32/boards/STM32F769DISC: Add config to use external SPI as filesys.
This board now has the following 3 build configurations:
- mboot + external QSPI in XIP mode + internal filesystem
- mboot + external QSPI with filesystem (the default)
- no mboot + external QSPI with filesystem

Damien George 7bb2bf965e stm32/Makefile: Allow a board's .mk file to add things to CFLAGS. 2020-01-30 14:39:46 +11:00
Andrew Leech 30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.
2020-01-30 13:18:38 +11:00
David Lechner b72cb0ca1b py/mpthread.h: Use strong type for mp_thread_set_state() argument.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.
2020-01-29 17:10:32 +11:00
Damien George a542c6d7e0 stm32/powerctrl: For F7, allow PLLM!=HSE when setting PLLSAI to 48MHz.
PLLM is shared among all PLL blocks on F7 MCUs, and this calculation to
configure PLLSAI to have 48MHz on the P output previously assumed that PLLM
is equal to HSE (eg PLLM=25 for HSE=25MHz).  This commit relaxes this
assumption to allow other values of PLLM.

David Lechner d89ed3e62b unix/unix_mphal: Add compile check for incompatible GIL+ASYNC_KBD_INTR.
It is not safe to enable MICROPY_ASYNC_KBD_INTR and MICROPY_PY_THREAD_GIL
at the same time.  This will trigger a compiler error to ensure that it
is not possible to make this mistake.
2020-01-26 23:31:27 +11:00
David Lechner bc3499f010 windows/windows_mphal: Release GIL during system calls.
This releases the GIL during syscalls that could block.
2020-01-26 23:27:40 +11:00
David Lechner fee7e5617f unix: Release GIL during all system calls.
Addition of GIL EXIT/ENTER pairs are:

- modos: release the GIL during system calls.  CPython does this as well.

- moduselect: release the GIL during the poll() syscall.  This call can be
  blocking, so it is important to allow other threads to run at this time.

- modusocket: release the GIL during system calls.  Many of these calls can
  be blocking, so it is important to allow other threads to run.

- unix_mphal: release the GIL during the read and write syscalls in
  mp_hal_stdin_rx_chr and mp_hal_stdout_tx_strn.  If we don't do this
  threads are blocked when the REPL or the builtin input function are used.

- file, main, mpconfigport.h: release GIL during syscalls in built-in
  functions that could block.
2020-01-26 23:21:29 +11:00
Damien George 96716b46e1 unix/Makefile: Reserve CFLAGS_EXTRA/LDFLAGS_EXTRA for external use.
When CFLAGS_EXTRA/LDFLAGS_EXTRA (or anything) is set on the command line of
a make invocation then it will completely override any setting or appending
of these variables in the makefile(s).  This means builds like the coverage
variant will have their mpconfigvariant.mk settings overridden.  Fix this
by using CFLAGS/LDFLAGS exclusively in the makefile(s), reserving the
CFLAGS_EXTRA/LDFLAGS_EXTRA variables for external command-line use only.
2020-01-24 11:51:21 +11:00
Yonatan Goldschmidt 35e664d779 tests/unix: Add coverage tests for mp_obj_is_type() and variants. 2020-01-24 10:57:17 +11:00
Damien George 27f41e624c tests/unix: Add coverage test for mp_obj_new_exception_args.
Because it's no longer called anywhere in the code.

stijn 599371b133 windows: Support word-based move/delete key sequences for REPL.
Translate common Ctrl-Left/Right/Delete/Backspace to the EMACS-style
sequences (i.e. Alt key based) for forward-word, backward-word, forwad-kill
and backward-kill.  Requires MICROPY_REPL_EMACS_WORDS_MOVE to be defined so
the readline implementation interprets these.

adzierzanowski a55c17dc69 esp32/modnetwork: Add max_clients kw-arg to WLAN.config for AP setting.
This allows the user to configure the maximum number of clients that are

Jim Mussared 3032ae1155 esp32: Enable NimBLE support on all builds (IDF 3.3 and 4.0).
This commit updates the IDFv3 version to v3.3.1, and enables the
"ubluetooth" module by default on IDFv3 builds.
2020-01-15 00:24:43 +11:00
JensDiemer c14ff6194c esp8266/modules: Fix AttributeError in _boot.py if flash not formatted.
Prior to this commit, if the flash filesystem was not formatted then it
would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'".
That is due to it not being able to detect the filesystem on the block
device and just trying to mount the block device directly.

This commit fixes the issue by just catching all exceptions.  Also it's not
needed to try the mount if `flashbdev.bdev` is None.
2020-01-14 23:53:49 +11:00
Memiks 4ab4bf3ec6 ports: Modify mp_hal_pin_write macro so it can be used as a function.

Thorsten von Eicken 6632dd3981 esp32/modmachine: Add implementation of machine.soft_reset(). 2020-01-12 13:38:45 +11:00
Yonatan Goldschmidt 853aaa06f2 lib/mp-readline: Add word-based move/delete EMACS key sequences.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively.  It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.

Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.

The features are enabled on unix micropython-coverage and micropython-dev.
2020-01-12 13:09:27 +11:00
Jim Mussared 977b532c8f unix: Rename unix binaries to micropython-variant (not _variant).
For consistency with mpy-cross, and other unix tools in general.
2020-01-12 10:37:40 +11:00
Jim Mussared 2357338e93 unix: Add placeholder DEV variant with settrace enabled.
This will eventually become the "full featured" unix binary with more
features enabled, specifically useful for development and testing.
2020-01-12 10:37:23 +11:00
Jim Mussared bd2fff6687 unix: Add build variants, analogous to boards on bare-metal.
Invoking "make" will still build the standard "micropython" executable, but
other variants are now build using, eg, "make VARIANT=minimal".  This
follows how bare-metal ports specify a particular board, and allows running
any make target (eg clean, test) with any variant.

Convenience targets (eg "make coverage") are provided to retain the old
behaviour, at least for now.

See issue #3043.
2020-01-12 10:34:23 +11:00
Damien George bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.
2020-01-09 11:25:26 +11:00
Damien George e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.
2020-01-07 23:59:29 +11:00
Damien George 99b8c1a937 esp32/Makefile: Assign result of $call to dummy var for older make.
Make version 4.1 and lower does not allow $call as the main expression on a

Fixes issue #5426.
2020-01-06 23:03:22 +11:00
Nicko van Someren 4c93955b7b py/objslice: Add support for indices() method on slice objects.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

Damien George 269c9a08b6 unix/modos: Add uos.rename and uos.rmdir.
The existing uos.remove cannot be used to remove directories, instead
uos.rmdir is needed.  And also provide uos.rename to get a good set of
filesystem functionality without requiring additional Python-level os
functions (eg using ffi).

Yonatan Goldschmidt 61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.
2019-12-28 00:05:39 +11:00
David Lechner e79424d672 ports: Allow overriding CROSS_COMPILE in a custom makefile.
Many ports already allow overriding CROSS_COMPILE.  This modifies the

Damien George 93509ac8c7 stm32: Add configuration to build in nanbox mode.
Most stm32 boards can now be built in nan-boxing mode via:

    $ make NANBOX=1

Note that if float is enabled then it will be forced to double-precision.
Also, native emitters will be disabled.

This commit refactors and generalises the boot-mount routine on stm32 so

assumes that the filesystem is FAT.  It does this by using mp_vfs_mount()
which does auto-detection of the filesystem type.

Damien George 799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.

This commit adds support for littlefs (v2) on all esp32 boards.

The original FAT filesystem still works and any board with a preexisting
FAT filesystem will still work as normal.  It's possible to switch to
littlefs by reformatting the block device using:

    import uos, flashbdev
    uos.VfsLfs2.mkfs(flashbdev.bdev)

Then when the board reboots (soft or hard) the new littlefs filesystem will
be mounted.  It's possible to switch back to a FAT filesystem by formatting
with uos.VfsFat.mkfs(flashbdev.bdev).

Damien George 48b25a841b stm32: Add machine.Timer with soft timer implementation.
This commit adds an implementation of machine.Timer backed by the soft
timer mechanism.  It allows an arbitrary number of timers with 1ms
resolution, with an associated Python callback.  The Python-level API
matches existing ports that have a soft timer, and is used as:

    from machine import Timer
    t = Timer(freq=10, callback=lambda t:print(t))
    ...
    t = Timer(mode=Timer.ONE_SHOT, period=2000, callback=lambda t:print(t))
    ...
    t.deinit()

Damien George a5d97f1db9 stm32: Add soft timer implementation, using SysTick at 1ms resolution.
This commit adds an implementation of a "software timer" with a 1ms
resolution, using SysTick.  It allows unlimited number of concurrent
timers (limited only by memory needed for each timer entry).  They can be
one-shot or periodic, and associated with a Python callback.

There is a very small overhead added to the SysTick IRQ, which could be
further optimised in the future, eg by patching SysTick_Handler code
dynamically.

When a SPI bus is initialized with a SPI host that is currently in use the

Damien George 1582c7eeb0 unix,windows: Enable module weak links. 2019-10-22 16:23:43 +11:00
Damien George d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

Jim Mussared 8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.
