576373552a atmel-samd: Run the VM hook while waiting for the UART read to timeout in case nothing is received. 2016-12-19 16:36:32 -08:00

b09a711eb0 Merge pull request #66 from tannewt/uart 
Thanks to @turbinenreiter for the first work on this.

I heavily modified it to work with a circular RX buffer of configurable size. The main API is the same as the stream API and is a subset of upstream's machine.UART.

Fixes #46

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.

0ae344841f atmel-samd & esp8266: Make sure pins are not already in use. 
This prevents corrupting previous functional objects by stealing their pins
out from under them. It prevents this by ensuring that pins are in default
state before claiming them. It also verifies pins are released correctly and
reset on soft reset.

Fixes #4, instantiating a second class will fail.
Fixes #29, pins are now reset too.

26229efe78 Add try_lock and unlock to I2C and SPI classes to make sure things 
are shared well between threads and underlying MicroPython (SPI Flash
for example.)

It is recommended to use the bus device classes to manage the locks
and other transaction state.

3b1109c47b Merge pull request #50 from tannewt/microcontroller 
Introduce shared APIs: nativeio, microcontroller and board modules. These are the only hardware API on the atmel-samd port.
 2016-11-21 14:30:57 -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.
