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

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.

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.

fffc6d1a17 atmel-samd: Add modules directory with frozen bytecode support (like ESP8266 port), and NeoPixel python wrapper module. 2016-10-14 11:39:42 +00:00

011056af15 atmel-samd: Add support for SPI. 
Also separate out the ASF config headers that are shared across all boards.

284d3414e1 atmel-samd: Make UART REPL Arduino Zero specific. Most will use USB REPL. 2016-10-07 15:06:07 -07:00

9c67605233 atmel-samd: Add low level neopixel_write module & function for WS281x/neopixel RGB LEDs. 2016-10-05 12:35:23 -07:00

7e08347d5c atmel-samd: Support composite CDC and mass storage USB device. 
Be careful to not use the flash file system while using mass storage
because both pieces of code attempting to change the fs can corrupt it.

1fa4c20c27 atmel-samd: Add Micro Trace Buffer support to the debug build. 
The Micro Trace Buffer records the history of the pc and can be used
to debug hard faults even when the stack trace is useless.

7d8929c470 atmel-samd: Add I2C support. 
This commit also introduces a new shared-bindings directory which is used to store the common Python -> C binding code. By having a shared directory we can ensure that the Python API across ports is the same. Each port will have a corresponding common-hal directory which provides definitions for the C api used in the shared-bindings code. That way the compiler can enforce the C api.

To migrate to this new shared API create a common-hal directory within your port and change the Makefile to compile both the shared-bindings and common-hal files. See atmel-samd/Makefile SRC_BINDINGS for an example.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly. 
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
