The whole idea was to get you to fire up the soldering iron. - f

The debouncing of the encoders is done in software, not hardware. This is the first time I have heard of a bounce problem anyway.? Take a look at the encoder code you could tweak it to increase the debounce time. ?

Each capacitor (.1uf) goes from? the phase A and B pin, to the encoder housing grounding trace. Plenty of room to incorporate these. Barry ? Sent from for Windows ? ? I am interested to know where you placed the capacitors. Can you show a drawing perhaps? ?

My display frequency would bounce back and forth. I noticed, on the schematic, that there are no capacitors to clean up the noise from the rotary encoder. I installed two .1uf caps on the encoder board and that took care of my issue. Have not noticed any problems with the multi function encoder though.
