Scott Shawcroft f4a1da4be9 atmel-samd: Only include bitbangio on boards with flash. 2016-12-01 13:46:44 -08:00
Scott Shawcroft 2d9a0c76c5 atmel-samd: Switch to MICROPY_PORT_ROOT_POINTERS for the flash cache. 2016-11-29 14:29:33 -08:00
Scott Shawcroft cc412a80ad atmel-samd: Support Trinket and Gemma M0 prototypes. 2016-11-22 12:03:42 -08:00
Scott Shawcroft ccbb5e84f9 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.

Scott Shawcroft f42b41e1e9 atmel-samd: Increase autoreset delay to reduce duplicate resets. 2016-10-31 11:31:33 -07:00
Scott Shawcroft 5b3a143ffe 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.

Scott Shawcroft 2098515f6a atmel-samd: Rework pin definitions to share most of the data structures and included based on ASF defines. 2016-10-26 17:57:47 -07:00
Scott Shawcroft 34fa81eaf3 atmel-samd: Hook in DTR for more ports and make the serial TX more resiliant to long strings. 2016-10-26 13:32:41 -07:00
Scott Shawcroft d189a3f3cf 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.

Scott Shawcroft d05299f57a atmel-samd: Add D13 led as mass storage write indicator. 2016-10-25 15:06:05 -07:00
Scott Shawcroft 16584dfee6 atmel-samd: Fix the Feather builds by switching to the VFS mass storage implementation. 2016-10-24 12:42:09 -07:00
Scott Shawcroft 306c921ed1 atmel-samd: Rework mass storage interaction with underlying block
storage to use micropython's VFS interface.

This makes mass storage work with any VFS implementation rather
than a single one.

Scott Shawcroft cb99ae5032 atmel-samd: Rename Feather M0 Bluefruit files to Feather M0 Basic because there isn't anything Bluefruit specific yet. 2016-10-14 13:10:17 -07:00
