CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=4.1.0-beta.0 2018-11-09T01:25:30+00:00 2018-11-09T01:25:30+00:00 Scott Shawcroft scott@tannewt.org 2018-10-20T01:46:22+00:00 urn:sha1:9d91111b1b6a1eee77a88b13faf695ee0c5caea3 This started while adding USB MIDI support (and descriptor support is in this change.) When seeing that I'd have to implement the MIDI class logic twice, once for atmel-samd and once for nrf, I decided to refactor the USB stack so its shared across ports. This has led to a number of changes that remove items from the ports folder and move them into supervisor. Furthermore, we had external SPI flash support for nrf pending so I factored out the connection between the usb stack and the flash API as well. This PR also includes the QSPI support for nRF. 2018-08-07T21:58:57+00:00 Scott Shawcroft scott@tannewt.org 2018-07-31T23:53:54+00:00 urn:sha1:933add6cd833bb6ba6682ad2b6eb478871415ff5 2018-07-31T20:50:48+00:00 Scott Shawcroft scott@tannewt.org 2018-07-31T20:39:12+00:00 urn:sha1:0bf999f52a50590f4c660df41aa979f39da04c38 2018-02-05T15:44:29+00:00 dean deanm1278@gmail.com 2018-02-05T15:44:29+00:00 urn:sha1:68309c3fac4c59cc6c22ffa0a9a7e64a582f6dfc 2018-01-30T22:18:57+00:00 dean deanm1278@gmail.com 2018-01-30T22:18:57+00:00 urn:sha1:a7f72eb2d8ecd7ee1d48935907e0e819e5efaca7 2017-10-03T19:07:17+00:00 Dan Halbert halbert@halwitz.org 2017-10-03T00:49:40+00:00 urn:sha1:c478c10923b9085b2abe135470e968029aaf2fdb Fixes #278, #277, #276, #275. 2017-04-12T22:24:50+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-04-12T22:24:50+00:00 urn:sha1:4a4f29b8f95aa67f63397ae4efe78c6994398ccf * 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. 2017-04-10T20:32:19+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. 2016-12-10T03:35:56+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-12-10T03:27:41+00:00 urn:sha1:b6f1eebab30b0e687e07cc3e42d9db9fd48aab05 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.

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
