c3afafd1ec samd/boards: Clean up comments and some pins in pins.csv files.
Remove two SPARKFUN_SAMD51_THINGS_PLUS pin definitions.  There were
definitions of TXD and RXD, but these pins do not exist on the board.  They
were only shown in the schematics.

Also remove any reference to LED_.  This is just a text change, no
functional change.

ac1e31267b samd/boards: Rework the pins.csv files.
Changes are:
- Remove the LED_Pxxx definitions from pins.csv, now that the LED class is
  gone.
- Remove the '-' lines.
- Add default lines for USB and SWCLK, SWDIO.

20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.

a9304af8fa samd/boards: Add missing/lost board config and pin definitions.
Fixes are:
- Pin definitions for ADAFRUIT_FEATHER_Mx_EXPRESS and
  ADAFRUIT_ITSYBITSY_M4_EXPRESS.
- For ADAFRUIT_ITSYBITSY_M0_EXPRESS, change the MISO/MOSI name.
- For MINISAM_M4, add the default SPI pins.
- For boards with 32k crystal, add the XOSC32K setting.

a5d5ecbf84 samd/boards: Move mcu-specific settings into a mpconfig_samdXX.h file.
Located at the boards directory. That way, the mpconfigboard.h files are
almost empty, just setting the board name and the MCU name.

0420799a84 samd/boards: Replace pins.c and pins.h by pins.csv.
The files pins.c and pins.h are generated during the build process from
pins.csv, using a make-pins.py script.

85afed569d samd: Remove the existing provisional support for REPL on UART.
It was only partially working and will be rpelaced later by a full
machine.UART class implementation.

199b6a8a8b samd/boards/ADAFRUIT_ITSYBITSY_M4_EXPRESS: Update for flash and pins.
- mpconfigboard.h: flash and USART config
- mpconfigboard.mk: enable LFS1
- pins.c: define pins and LEDs
- pins.h: define structs and consts

7f14344428 ports: Add images, features and urls to board.json. 2021-10-28 15:25:38 +11:00

e359b077dd ports: Add board.json for all boards.
This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.

Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

a5d85d306c samd: Make common linker scripts, rename board.mk to mpconfigboard.mk.
The rename matches other ports, e.g. stm32, and gives consistency with
mpconfigboard.h.

5f9bd11527 samd: Add new port to Microchip SAMDxx microcontrollers.
