suspect-devices/circuitpython/shared-bindings/nativeio/AnalogIn.h, branch 6.2.x CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=6.2.x 2017-04-10T20:32:19+00:00 Split up nativeio. 2017-04-10T20:32:19+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-04-10T20:32:19+00:00 urn:sha1:f28f8ba56809fd56e777eabceae21127f95b89ed This was done to allow greatly granularity when deciding what functionality is built into each board's build. For example, this way pulseio can be omitted to allow for something else such as touchio. Fix up Analog classes: unify them at 16 bits and adds reference_voltage member 2016-12-14T00:09:00+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-12-14T00:09:00+00:00 urn:sha1:781633c716a2d0dc32ebf352fb5dd5ffdecad1d3 to make for easy conversion. Fixes #14. atmel-samd & esp8266: Make sure pins are not already in use. 2016-12-07T23:21:14+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-12-06T18:31:38+00:00 urn:sha1:0ae344841ff048424b886e1f386b16c0c9ba4ee2 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. 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. 2016-11-21T22:11:52+00:00 Scott Shawcroft scott@chickadee.tech 2016-11-03T22:50:59+00:00 urn:sha1:ccbb5e84f980e252f7380d96fcc5c417a8a64523 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.
