Re: QCX Troubleshooting - Please can you help?
|
The encoder part sounds a bit strange, it has dedicated pins to the micro and does not operate in analog mode. Put the scope on those two pins and while rotating the encoder see that it looks like a clean square wave with 5V amplitude. The chip has built in pullup (activated by the program) so the positive going flank should have more of a rounded edge than the negative.
Nothing wrong with the socket? like pins not sitting properly ? Scoping the sidetone pin 15 should also show a square wave, at 700Hz or whatever it is set to in the menus. Perhaps doing a factory reset, woult not hurt and eliminates any possible strange settings messing something up.
