Question on interfacing a rotary encoder with M68HC11 for jhance
Posted on 1998-12-05
Well.. I'm the previous Mr MFC hehee... I've got your message, I've got a scanner and do you want me to scan the specifications and send it to you or just write it down here again?
Just to update you, I'm now able to see the logic level drop from '1' to '0' as I move the encoder. But this only happens for output A and output B, output Z remains logic '1' no matter how I move the encoder, is this the correct result? Also for output A and output B, even if I rotate the encoder in the opposite direction for the output A or B, the logic level will still drop from '1' to '0', is this the correct result? If this is the correct result, then how can I differentiate the direction in which the encoder is turning? Please advice and help thanks!
