Scott Shawcroft 790c38e18c atmel-samd: Rework boot, main and REPL order.
Boot will only run once now before USB is started. Its output goes to
boot_out.txt. After main and REPL will run with VM and hardware resets
between each.

Scott Shawcroft b6f1eebab3 atmel-samd: Add APA102 support and flash more advanced status.
The new sequence is as follows:
* Solid blue during the boot/settings script.
* Solid green during the main/code script.
* After main while waiting to enter repl or reset:
  * Fading green once main is done successfully.
  * On error produce a series of flashes:
    * Long flash color of script.
    * Long flash color of error:
      * Green = IndentationError
      * Cyan = SyntaxError
      * White = NameError
      * Orange = OSError
      * Yellow = Other error
    * Line number of the exception by digit. Number of flashes represents value.
      * Thousands = White
      * Hundreds = Blue
      * Tens = Yellow
      * Ones = Cyan
    * Off for a period and then repeats.

At any point a write to the flash storage will flicker red.

Fixes #63

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 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.

Tony DiCola 903bc8d04e atmel-samd: Implement time.ticks_ms function using SysTick timer, add global interrupt enable/disable functions. 2016-10-13 04:59:43 +00:00
Scott Shawcroft eff137a5f5 atmel/samd: Support CTRL-C on USB. This won't escape native code but it will cause Python code to stop. 2016-08-31 00:11:56 -07:00
