* Never drive SDL or SDA high. They are specified to be open collector/drain and pulled up by resistive pullups. Driving high fails miserably in a multi-master topology (e.g. with a USB I2C interface). It would only ever be implemented to speed up the bus actively but that's tricky and completely unnecessary here. * Make the handover states between the I2C protocol phases (start, stop, restart, write, read) well defined. Add comments stressing those pre/postconditions. * Add checks for SDA arbitration failures and stuck SCL. * Remove wrong, misleading or redundant comments. |
