     91Please note that this is just an example I extracted from my software. The method check_encoders() has to be called everytime when there is a change in encoder state. This can be achieved by polling the encoders. Other way could be to interface both encoders with PCF8574 and to wait on the interrupt indicating that output of encoders changed. The latter case is implemented in the hardware of OpenBM.
