Software I2C is used for other MCUs. stmhal: Add beginnings of port-specific machine.I2C implementation. 2016-11-23T13:20:51+00:00 Damien George damien.p.george@gmail.com 2016-11-23T13:20:51+00:00 urn:sha1:30537489877fd77e129623f93d3921f547668fb8 This allows one to construct an I2C object using ids that are specific to the stmhal port, eg machine.I2C('X'). Right now the implementation of I2C uses software I2C but the idea is to just change the C-level I2C protocol functions to hardware implementations later on.
