For example, this way pulseio can be omitted to allow for something else such as touchio. shared-bindings: Do a pass on the docs and make sure keyword only arguments make sense and are documented correctly.

It saves a little code space each time to share the call. 2017-02-24T14:13:07+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-24T14:13:07+00:00 urn:sha1:12fa5b3a66d6f0034113a56c7d647c7bac5be74c Switch enum-like attributes to all caps and add print support for them. Make room for this functionality by adding a shared __enter__ function object. #76 2017-02-19T15:11:33+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-19T15:11:33+00:00 urn:sha1:e9659e61f89fb9ef84011c42e89849f7fd9bc9c1 nativeio.SPI: Remove extraneous constructor args because they are in configure. 2017-02-19T11:57:00+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-19T11:57:00+00:00 urn:sha1:1a3bd67833f492ca59b4f3a116c7eff98bb204d1 SPI tweaks for SD Cards: 2017-02-10T13:09:17+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-01-21T00:52:53+00:00 urn:sha1:370d1dec888e661d2cc23d38bb444d95d8d2a141 * Always init SPI to 250k to start for SD cards. * Add ability to configure byte written during read. * Add ability to read and write to portions of buffers like existing I2C API.

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. Add try_lock and unlock to I2C and SPI classes to make sure things 2016-12-02T23:46:12+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-11-30T23:08:34+00:00 urn:sha1:26229efe78f6c5f8598d6f9f1b2261c5a84d7a7b 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
