Everything should be using the keypad module instead.
Note: there are several boards that still had gamepadshift enabled. I
did not contact their authors to make sure they already switched to
keypad in their code and documentation. We should probably wait with
merging this for their go ahead.
Removes:
* AUTORESET_DELAY_MS which never did anything but was introduced
somehow.
* CIRCUITPY_BOOT_BUTTON in all but one ESP board because they all have
them. There is a default based on the strapping pins.
* BOARD_USER_SAFE_MODE_ACTION because it was all the same for boards
with boot buttons. Now the safe mode code manages the message.
This unifies the delay into the post-run delay that also waits
for user input and fake sleep. This ensures we always delay.
Previous code would only delay if the code.py was running when
autoreload was triggered. Now it will always delay.
We also now suspend autoreload when a USB write starts and then
resume on completion. This should prevent reloading in between
sectors of a single write.
- Add reset for autoreload. De-request ticks.
- Separate state a little more in autoreload.c
- Rename some routines.
- Remove redundant settings of CIRCUITPY_AUTORELOAD_DELAY_MS.
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)
Related to #5986
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.

F-strings, new machine.I2S class, ESP32-C3 support and LEGO_HUB_NO6 board
This release of MicroPython adds support for f-strings (PEP-498), with a
few limitations compared to normal Python. F-strings are essentially
syntactic sugar for "".format() and make formatting strings a lot more
convenient. Other improvements to the core runtime include pretty printing
OSError when it has two arguments (an errno code and a string), scheduling
of KeyboardInterrupt on the main thread, and support for a single argument
to the optimised form of StopIteration.
In the machine module a new I2S class has been added, with support for
esp32 and stm32 ports. This provides a consistent API for transmit and
receive of audio data in blocking, non-blocking and asyncio-based
operation. Also, the json module has support for the "separators" argument
in the dump and dumps functions, and framebuf now includes a way to blit
between frame buffers of different formats using a palette. A new,
portable machine.bitstream function is also added which can output a stream
of bits with configurable timing, and is used as the basis for driving
WS2812 LEDs in a common way across ports.
There has been some restructuring of the repository directory layout, with
all third-party code now in the lib/ directory. And a new top-level
directory shared/ has been added with first-party code that was previously
in lib/ moved there.
The docs have seen further improvement with enhancements and additions to
the rp2 parts, as well as a new quick reference for the zephyr port.
The terms master/slave have been replaced with controller/peripheral,
mainly relating to I2C and SPI usage. And u-module references have been
replaced with just the module name without the u-prefix to help clear up
the intended usage of modules in MicroPython.
For the esp8266 and esp32 ports, hidden networks are now included in WLAN
scan results. On the esp32 the RMT class is enhanced with idle_level and
write_pulses modes. There is initial support for ESP32-C3 chips with
GENERIC_C3 and GENERIC_C3_USB boards.
The javascript port has had its Makefile and garbage collector
implementation reworked so it compiles and runs with latest the Emscripten
using asyncify.
The mimxrt port sees the addition of hardware I2C and SPI support, as well
as some additional methods to the machine module. There is also support
for Hyperflash chips.
The nrf port now has full VFS storage support, enables source-line on
traceback, and has .mpy features consistent with other ports.
For the rp2 port there is now more configurability for boards, and more
boards added.
The stm32 port has a new LEGO_HUB_NO6 board definition with detailed
information how to get this LEGO Hub running stock MicroPython. There is
also now support to change the CPU frequency on STM32WB MCUs. And USBD_xxx
descriptor options have been renamed to MICROPY_HW_USB_xxx.

Fixes build error:
```
In file included from ../../py/mpstate.h:33,
from ../../py/mpstate.c:27:
../../py/misc.h: In function 'vstr_str':
../../py/misc.h:196:1: sorry, unimplemented: Thumb-1 hard-float VFP ABI
static inline char *vstr_str(vstr_t *vstr) {
^~~~~~
```
Sleuthing steps:
* verify that the feather_stm32f4_express board builds correctly
* put a `#error` at the bottom of the `mpstate.c` file.
* build for the feather and swan boards, with V=2 to capture the build command for that file.
* use a differencing tool to inspect the differences between the two invocations
* inspecting the differences, I saw a missing `-mcpu=cortex-m4` I tested by adding that to the Swan build command. The file built fine (stopping at the hard error, but no other warnings.)
A grep through the sources revealed where this flag was being set for the stm ports.
With this commit, the build gets further, but does not complete. The next exciting episode in this unfolding coding saga is just a commit away!
working build with minimal set of modules for the Blues Swan r5
chore:change header copyright name to Blues Wireless Contributors
USB operational. Fixed up clocks to be hardwired for LSE no HSE case. (Trying to combine HSE in there made the code much more complex, and I don't have a board to test it out on.)
USART working
adds support for `ENABLE_3V3` and `DISCHARGE_3V3` pins. I am surprised that pin definitions are quite low-level and don't include default direction and state, so the code currently has to initialize `ENABLE_3V3` pin as output. The LED takes over a second to discharge, so I wonder if the board startup code is not having the desired affect.
short circuit implementation of backup memory for the STM32L4
all the ports
remove company name from board name to be consistent with the Arduino board definition.
add default pins for I2C, SPI and UART, so that `board.I2C` et al. works as expected. Confirmed I2C timing.
fix board name
fix incorrect pin definition. add test to allow manual check of each output pin
analog IO
code changes for WebUSB. Doesn't appear to work, will revisit later.
ensure that `sys.platform` is available
checkin missing file
feat: make room for a larger filesystem so the sensor tutorial will fit on the device.
fix:(stm32l4r5zi.csv): merged AF0-7 and AF8-15 into single lines and removed extraneous headers mixed in with the data.
fix(parse_af_csv.py): pin index in the csv is 0 not 1, and AF index made 1 larger
chore(Swan R5): update peripherals pins from `parse_af_csv.py` output
optimize flash sector access
This enables the _stage library and adds stage and ugame modules to the
frozen modules, so that all Stage games should work.
I had to do several hacks:
* Since displayio.release_displays doesn't release the pins, I couldn't
re-initialize the display inside the ugame module. Instead I changed
the default display initialization for the board to match what Stage
expects.
* I wanted to make the MENU key works as K_Z, but when I try to use it
with the keypad module, I get "pin in use" error. So for now only the
A and B buttons are used.
There is a race between when we run background tasks and when we
sleep. If an interrupt happens between the two, then we may delay
executing the background task. On some ports we checked this for
TinyUSB already. On iMX RT, we didn't which caused USB issues.
This PR makes it more generic for all background tasks including
USB.
Fixes#5086 and maybe others.
Passing in a PWMOut still works but is deprecated. It will be
removed in CircuitPython 8.0.0
This also switches STM32 timer indices and channel indices to
0-based in our pin data rather than `- 1` everywhere. The latter is
more bug prone.
Most of the way for #3264
Tested on Metro M0, Metro M4, Feather S2, Feather nRF52840, Feather
STM32F4 and Arduino RP2040.
This configuration is used by @ladyada and more often than it should
we've discovered late that a change introduced problems building
there.
By adding this to regular CI, hopefully we learn about and fix these
issues sooner rather than later.
This also removes the need to pin share because we don't use the
status LED while user code is running.
The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.
One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.
Fixes#4133
In #4683, tannewt noticed that uncrustify was not running on some
file in common-hal.
I investigated and found that it was not being run on a bunch of paths.
Rather than make incremental changes, I rewrote list_files to work
bsaed on regular expressions; these regular expressions are created from
the same git-style glob patterns.
I spot-checked some specific filenames after this change, and all looks good:
```
$ python3 tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c

recursiveloop and int_small are excluded, while PulseIn, virtpin,
and background are included.

As a side-effect, a bunch more files are re-formatted now. :-P
