Also, bring the bitbangio into compatibility with busio wrt. empty buffers. Do not allow a *io object to be used after deinit(). 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. shared-bindings: Update docs to remove with statements from examples but add more detail to the design guide about their use. 2017-06-07T21:39:12+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-06-07T21:39:12+00:00 urn:sha1:714521a4c7a6814c365c061bcf967c4c45692e3d Switch to a shared piece of code to compute start and length of a 2017-04-20T18:24:05+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-04-20T18:24:05+00:00 urn:sha1:939c0045dbf2694a12432ad861db166ecf483b67 buffer from start, end and length. The old code miscomputed length leading to writing and reading from memory past the end of the buffer. Consolidating the code should make it easier to get right everywhere. shared-bindings: Do a pass on the docs and make sure keyword only arguments make sense and are documented correctly.

(Read didn't used to fail at all.) 2) try_lock correctly returns boolean whether lock was grabbed. Fixes #87 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 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.)
