Hi Tom. I have 6 axis and 5 encoders. So there is no available ports. The IO24 can be damaged? Because it was working fine, and now it always return true. If I disconnect the encoder and then connect IO24 to 3.3v it works fine.
The same happend with IO25.
Do you think that we can use a simple optoisolator 6N137 with rc filter, 5V at the output, and connect it to konnect board? Or RC Filter + 6N137 + OP-AMP with 12V? Or maybe it can be solved usign Kanalog?
