2018-05-13 add timeout keyword to I2C - for bitbangio - ignored for busioJerry Needell
2017-10-03Do not allow a *io object to be used after deinit().Dan Halbert
Fixes #278, #277, #276, #275.
2017-08-25Initial merge of micropython v1.9.2 into circuitpython 2.0.0 (in ↵Dan Halbert
development) master. cpx build compiles and loads and works in repl; test suite not run yet esp8266 not tested yet
2017-04-12atmel-samd: Rework status LED implementationScott Shawcroft
* Track status pin use by user code separately so it can take over the pins and then give them back. * Switch to hardware SPI for APA102 on Gemma and Trinket. * Merge microcontroller/types.h into microcontroller/Pin.h to better match approach going forwards.
2017-02-19Two I2C fixes:Scott Shawcroft
1) Bus error will be thrown on read/write errors with errno set. (Read didn't used to fail at all.) 2) try_lock correctly returns boolean whether lock was grabbed. Fixes #87
2016-12-02Add try_lock and unlock to I2C and SPI classes to make sure thingsScott Shawcroft
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. https://github.com/adafruit/Adafruit_MicroPython_BusDevice Fixed #58 Fixed #59 Fixed #60
2016-11-21This introduces an alternative hardware API called nativeio structured ↵Scott Shawcroft
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.
