- Makefile: update to use new ASF4 files, support frozen manifest, and
include source files in upcoming commits
- boards/manifest.py: add files to freeze
- boards/samd51p19a.ld: add linker script for this MCU
- help.c: add custom help text
- main.c: execute _boot.py, boot.py and main.py on start-up
- modules/_boot.py: startup file to freeze
- modutime.c: add gmtime, localtime, mktime, time functions
- mpconfigport.h: enabled more features for sys and io and modules
- mphalport.h: add mp_hal_pin_xxx macros
- mphalport.c: add mp_hal_stdio_poll
Don't force the 'HAL' string to be part of the platform string because
it doesn't have a sensible meaning for all possible platforms, and
swap it with the PLATFORM_ARCH string so the strings which most platforms
have come first.
Although the pyboard has only 4 LEDs, there are some boards that (may) have
more. This commit adds 2 more LEDs to the led.c file that if defined in
the board-specific config file will be compiled in.
This commit swaps the dimensions of the `framebuffer.FrameBuffer` in the
docs example from 10x100 to 100x10 pixels to avoid clipping.
This is done to better fit the subsequent example code, which writes
text of size 96x8 followed by a 96x1 horizontal line.
The y coordinate of the horizontal line is also adjusted such that it is
drawn inside of the new canvas bounds.
Expected result of const.py will be matched only when MICROPY_COMP_CONST is
enabled. For easy understanding, added description at the first of the
test code.
Some toolchains will have string.h defining various macros which can lead
to compile errors for string function implementations. Not including
string.h fixes this.
An implementation of __memcpy_chk is provided for toolchains that enable
_FORTIFY_SOURCE.
Fixes issue #6046.

- Add board.md files for MIMXRT1060_EVK and MIMXRT1064_EVK warning about
their experimental state.
- Add separate deploy_teensy.md and deploy_mimxrt.md files.
The ARCH MIX board exposes the Ethernet Pins at it's connectors. Therefore
the software is configured for using a LAN8720 PHY device. Breakout boards
with the LAN8720 are easily available.
This commit adds I2S protocol support for the rp2 port:
- I2S API is consistent with STM32 and ESP32 ports
- I2S configurations supported:
- master transmit and master receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequency
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- internal ring buffer size can be tuned
- DMA IRQs are managed on an I2S object basis, allowing other
RP2 entities to use DMA IRQs when I2S is not being used
- MicroPython documentation
- tested on Raspberry Pi Pico development board
- build metric changes for this commit: text(+4552), data(0), bss(+8)

Eliminate noise data from being sent to the I2S peripheral when the
transmitted sample stream is stopped.

Now that there are feature levels, and that this port uses
MICROPY_CONFIG_ROM_LEVEL_MINIMUM, it's easy to see what optional features
can be disabled. And this commit disables them.

Word-size specific configuration is now done automatically, so it no longer
requires this to match the ARM configuration.
Also it's less common to have 32-bit compilation support installed, so this
will make it work "out of the box" for more people.

This makes it possible for cooperative multitasking systems to keep running
event loops during garbage collector operations.
For example, this can be used to ensure that a motor control loop runs
approximately each 5 ms. Without this hook, the loop time can jump to
about 15 ms.
Addresses #3475.

This is an stm32-specific feature that's accessed via the pyb module, so
not something that will be widely enabled.

This commit is a no-op change. Future improvements can come from making
individual boards use CORE or BASIC.

Some of these will later be moved to CORE or BASIC, but EXTRA is a good
starting point based on what stm32 uses.

Prior to this commit IRQs on STM32F4 could be lost because SR is cleared by
reading SR then reading DR. For example, if both RXNE and IDLE IRQs were
active upon entry to the IRQ handler, then IDLE is lost because the code
that handles RXNE comes first and accidentally clears SR (by reading SR
then DR to get the incoming character).
This commit fixes this problem by making the IRQ handler more atomic in the
following operations:
- get current IRQ status flags
- deal with RX character
- clear remaining status flags
- call user handler
On the STM32F4 it's very hard to get this right because the only way to
clear IRQ status flags is to read SR then DR, but the read of DR may read
some data which should remain in the register until the user wants to read
it. And it won't work to cache the read because RTS/CTS flow control will
then not work. So instead the new code disables interrupts if the DR is
full and waits for the user to read it before reenabling the interrupts.
Fixes issue mentioned in #4599 and #6082.

Following on from ba940250a5, the change here
makes output about 15 times faster (now up to about 550 kbytes/sec).
tinyusb_cdcacm_write_queue will return the number of bytes written, so
there's no need to use tud_cdc_n_write_available.
