* Add _ prefix to constants so they are compiled in by mpy-cross. * Make violet and similar the calibrated value. Raw values are raw_* * Replace while 1s with while Trues. * Change numeric properties to tuple of valid values so values are simple data types (int and float) rather than ENUMs. * Add mode documentation so the datasheet isn't needed to understand them.
