The mpconfigport.h file is an internal header and should only ever be
included once by mpconfig.h.

Updating to Black v20.8b1 there are two changes that affect the code in
this repository:
- If there is a trailing comma in a list (eg [], () or function call) then
that list is now written out with one line per element. So remove such
trailing commas where the list should stay on one line.
- Spaces at the start of """ doc strings are removed.

Enabling the following features for all targets, except for nrf51
targets compiled to be used with SoftDevice:
- MICROPY_PY_ARRAY_SLICE_ASSIGN
- MICROPY_PY_SYS_STDFILES
- MICROPY_PY_UBINASCII
Splitting mpconfigport.h into multiple device specific
files in order to facilitate variations between devices.
Due to the fact that the devices might have variations in
features and also variations in flash size it makes sense
that some devices offers more functionality than others
without being limited by restricted devices.
For example more micropython features can be activated for
nrf52840 with 1MB flash, compared to nrf51 with 256KB.
This commit adds time.ticks_ms/us support using RTC1 as the timebase. It
also adds the time.ticks_add/diff helper functions. This feature can be
enabled using MICROPY_PY_TIME_TICKS. If disabled the system uses the
legacy sleep methods and does not have any ticks functions.
In addition support for MICROPY_EVENT_POLL_HOOK was added to the
time.sleep_ms(x) function, making this function more power efficient and
allows support for select.poll/asyncio. To support this, the RTC's CCR0
was used to schedule a ~1msec event to wakeup the CPU.
Some important notes about the RTC timebase:
- Since the granularity of RTC1's ticks are approx 30usec, time.ticks_us is
not perfect, does not have 1us resolution, but is otherwise quite usable.
For tighter measurments the ticker's 1MHz counter should be used.
- time.ticks_ms(x) should *not* be called in an IRQ with higher prio than
the RTC overflow irq (3). If so it introduces a race condition and
possibly leads to wrong tick calculations.
See #6171 and #6202.
When compiling for debug (-O0) the .text segment cannot fit the flash
region when MICROPY_ROM_TEXT_COMPRESSION=1, because the compiler does not
optimise away the large if-else chain used to select the correct compressed
string.
This commit enforces MICROPY_ROM_TEXT_COMPRESSION=0 when compiling for
debug (DEBUG=1).
The storage space of the advertisement name is not declared static, leading
to a random advertisement name. This commit fixes the issue by declaring
it static.
The Bluetooth link gets disconnected when connecting from a PC after 30-40
seconds. This commit adds handling of the data length update request. The
data length parameter pointer is set to NULL in the reply, letting the
SoftDevice automatically set values and use them in the data length update
procedure.
mp_keyboard_interrupt() triggers a compiler error because the function is
implicitly declared. This commit adds "py/runtime.h" to the includes.
Fixes issue #5732.
Commit 6cea369b89 updated the TinyUSB
submodule to a version based on nrfx v2.0.0. This commit updates the nrf
port to work with the latest TinyUSB and nrfx v2.0.0.
Because it can confuse older versions of gcc. Instead use the correct
instruction for Thumb vs Thumb-2 (sub vs subs) so the assembler emits the
2-byte instruction.
Related to commit 1aa9ff9141.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
Now that error string compression is supported it's more important to have
consistent error string formatting (eg all lowercase English words,
consistent contractions). This commit cleans up some of the strings to
make them more consistent.
This function is not used by the core but having it as part of the build
allows it to be used by user C modules, or board extensions. The linker
won't include it in the final firmware if it remains unused.
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.
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.
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.
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.
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.
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.
