Damien George 894c550c86 stm32: Refactor bluetooth stack/hci/driver bindings.
This makes a cleaner separation between the: driver, HCI UART and BT stack.
Also updated the naming to be more consistent (mp_bluetooth_hci_*).

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George c44d52f33e extmod/modbluetooth_nimble: Move nimble specific code, factor nimble.mk.
Move extmod/modbluetooth_nimble.* to extmod/nimble.  And move common
Makefile lines to extmod/nimble/nimble.mk (which was previously only used
by stm32).  This allows (upcoming) btstack to follow a similar structure.

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George 44aa5b2200 stm32/modnetwork: Remove redundant call to nimble_poll in lwip poll.
The bluetooth stack has its own dedicated polling function, see
mod_bluetooth_nimble_poll_wrapper().

Damien George 3e0b46b9af unix/file: Don't raise OSError(EINVAL) on sys.stdin/out/err.flush().
sys.stdout.flush() is needed on CPython to flush the output, and the change
in this commit makes such an expression also work on MicroPython (although
MicroPython doesn't actual need to do any flushing).

Damien George 69661f3343 all: Reformat C and Python source code with tools/codeformat.py.
This is run with uncrustify 0.70.1, and black 19.10b0.
2020-02-28 10:33:03 +11:00
Damien George 3f39d18c2b all: Add *FORMAT-OFF* in various places.
This string is recognised by uncrustify, to disable formatting in the
region marked by these comments.  This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less
readable.

Damien George 73670ef281 unix/unix_mphal: Adjust #if in mp_hal_stdin_rx_chr to improve format. 2020-02-28 10:30:28 +11:00
hahmadi b169904254 stm32/mpconfigport.h: Add option to have custom help text.
Define MICROPY_PY_BUILTINS_HELP_TEXT in <yourboard>/mpconfigboard.h for a
custom help text.
2020-02-21 15:02:19 +11:00
Damien George 410757f4f4 unix/mphalport.h: Fix build when MICROPY_USE_READLINE=0.
If the built-in input() is enabled (which it is by default) then it needs
some form of readline, so supply it with one when MICROPY_USE_READLINE=0.

Fixes issue #5658.

Jim Mussared a9ce8dfdaa esp32: Move to IDF 4.0 release version. 2020-02-20 00:34:31 +11:00
David Lechner 4adcaa4423 unix/mpthreadport: Fix Mac build by using SIGUSR1 if SIGRTMIN not avail.
Some platforms, like Apple, don't define SIGRTMIN, so fall back to SIGUSR1
in such a case.

Fixes #5659.

Andrew Leech 3fe83e4318 stm32/sdram: Fix compile issue from unused sdram startup test flag. 2020-02-18 14:22:03 +11:00
David Lechner 3bd2ae1a36 unix/mpthreadport: Use SIGRTMIN+5 instead of SIGUSR1 for thread-GC.
This changes the signal used to trigger garbage collection from SIGUSR1 to
SIGRTMIN + 5.  SIGUSR1 is quite common compared to SIGRTMIN (measured by
google search results) and is more likely to conflict with libraries that
may use the same signal.

POSIX specifies that there are at least 8 real-time signal so 5 was chosen
as a "random" number to further avoid potential conflict with libraries
that may use SIGRTMIN or SIGRTMAX.

Also, if we ever have a `usignal` module, it would be nice to leave SIGUSR1
and SIGUSR2 free for user programs.

Damien George ac8383a95d nrf: Use MICROPY_HW_ENABLE_RNG instead of MICROPY_PY_RANDOM_HW_RNG.
The "random" module no longer uses the hardware RNG (the extmod version of
this module has a pseudo-random number generator), so the config option
MICROPY_PY_RANDOM_HW_RNG is no longer meaningful.  This commit replaces it
with MICROPY_HW_ENABLE_RNG, which controls whether the hardware RNG is
included in the build.
2020-02-18 12:43:16 +11:00
Damien George 6ad3bb1e12 nrf: Remove custom "random" module and use extmod version instead.
Hardware RNG code is moved to drivers/rng.[ch].

cccc 4f3e5ea934 nrf/drivers/bluetooth: Fix variable initialisation error with older gcc.
Without this change, arm-none-eabi-gcc version 4.9.3 (at least) would give
a "missing braces around initializer" error.
2020-02-16 23:46:27 +11:00
David Lechner 4af79e7694 unix/Makefile: Allow to install all variants of the executable.
The install target is current broken when PROG is used to override the
default executable name.  This fixes it by removing the redundant TARGET
variable and uses PROG directly instead.

The install and uninstall targets are also moved to the common unix
Makefile so that all variants can be installed in the same way.
2020-02-16 23:37:40 +11:00
David Lechner c5f4268c99 unix/variants/standard: Fix role of PREFIX when used to install.
Currently it is not possible to override PREFIX when installing micropython
using the makefile.  It is common practice to be able to run something like
this:

    $ make install PREFIX=/usr DESTDIR=/tmp/staging

This fixes such usage.
2020-02-16 23:35:52 +11:00
Damien George baf11f237b unix/Makefile: Remove old variant targets that are no longer needed.
To eliminate confusion about what targets to use when building.

Damien George ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

   bare-arm:   +28 +0.042%
minimal x86:  +100 +0.067%
   unix x64:   -56 -0.011%
unix nanbox:  -300 -0.068%
      stm32:  -204 -0.054% PYBV10
     cc3200:    +0 +0.000%
    esp8266:   -64 -0.010% GENERIC
      esp32:  -104 -0.007% GENERIC
        nrf:  -136 -0.094% pca10040
       samd:    +0 +0.000% ADAFRUIT_ITSYBITSY_M4_EXPRESS
2020-02-13 11:52:40 +11:00
Damien George 97eca38c4f py: Add mp_raise_type helper macro and use it where appropriate.
This provides a more consistent C-level API to raise exceptions, ie moving
away from nlr_raise towards mp_raise_XXX.  It also reduces code size by a
small amount on some ports.

Damien George 5a755ac30a esp32/modsocket: Convert EADDRINUSE error code from lwip return value. 2020-02-11 13:59:09 +11:00
stijn 5f91933e54 windows: Improve default search path.
The default value for MICROPYPATH used in unix/main.c is
"~/.micropython/lib:/usr/lib/micropython" which has 2 problems when used in
the Windows port:
- it has a ':' as path separator but the port uses ';' so the entire string
  is effectively discarded since it gets interpreted as a single path which
  doesn't exist
- /usr/lib/micropython is not a valid path in a standard Windows
  environment

Override the value with a suitable default.
2020-02-11 13:34:35 +11:00
stijn 8b6e6008c7 unix/main: Use OS-dependent path separator when searching path. 2020-02-11 13:33:56 +11:00
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.
2020-02-11 11:45:14 +11:00
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).
2020-02-07 16:08:37 +11:00
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.
2020-02-07 16:08:31 +11:00
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.

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.
2020-02-04 18:18:41 +11:00
Jim Mussared 0645478475 esp32/Makefile: Reorder includes to build with latest toolchain.
Tested on:
- IDF3.3.1 (old toolchain)
- IDF4.0-beta1 (old toolchain)
- IDF4.0-beta1 (new toolchain from install.sh / export.sh)
2020-02-04 18:06:14 +11:00
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.
2020-02-04 17:09:19 +11:00
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.
2020-02-01 22:44:08 +11:00
