atmel-samd: Add basic support for experimental Metro M0 with an external flash chip.
2016-10-07 18:09:01 -04:00
// #define UART_REPL
#define USB_REPL
#define MICROPY_HW_BOARD_NAME "Adafruit Metro M0 with Flash (Experimental)"
#define MICROPY_HW_MCU_NAME "samd21g18"
atmel-samd: Turn off using the red LED to show mass storage writes.

atmel-samd: Support external flash on the Metro M0 w/Flash. This uses a scratch flash sector to save data before writing a full sector.

This introduces an alternative hardware API called nativeio structured around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware. Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/ It differs from upstream's machine in the following ways: * Python API is identical across ports due to code structure. (Lives in shared-bindings) * Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC). * Documentation lives with code making it easy to ensure they match. * Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut). * All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware. * All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.

atmel-samd: Rework tick timer to use TC5 and support neopixel status LED. The tick timer needed to be reworked because the ASF delay functions also use the SysTick timer. Now, it uses TC5 and calls out to the autoreset logic every tick. Fixes #43. Added neopixel status colors and corrected the latch time from ms to us. Fixes #42.

atmel-samd: Support auto-reset based on USB write activity. It will soft-reboot micropython after a burst of writes to the file system. This means that after you save files on your computer they will be automatically rerun. This can be disabled in the build by unsetting AUTORESET_TIMER in mpconfigboard.h. Using the REPL will also prevent the soft resets until you reset with CTRL-D manually.
