Hi JW,Thanks for guidance I ended up having the encoder generate an output clock to feed another timer and that timer used the encoder clock output as the trigger source for input capture. I then enabled the input capture (IC) interrupt and added the...

Hi JW,Thanks for reviewing and your answer. I'd still like to make the process more automated than polling so I think I would need to implement an interrupt to detect a change in the encoder. Could you confirm my understanding on this as well?the enc...
