I'm having a slight issue with my mcp23017 not being detected if I turn my rotary encoder too fast. My rotary encoder has three pins, the middle for ground, and the other two connected to two pins (1 and 2) on my mcp23017.
Now, I think I may no the problem. It seems that if I turn the rotary encoder too fast, it shorts out both of the GPIO's instead of just one of them (pin1 || pin 2).
Could somebody please tell me if they've had similar issues please?
