Sorry, I have not gotten around to it.


Really all I needed to do was change the "debounce" circuit.

It needs to look like this (Figure 2) on each side of the encoder

Debouncing Contacts Part 2

 

Then you just need to adjust the resistor/capacitor combination to vary the length of bounce suppression.

The CMOS Cookbook has a table of combo's as a guide to the length of Charge/Discharge.

Hope that helps until I can sit down with the editor and redo the schematic.
