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.
