Rotary switch encoder problem
« on: November 20, 2019, 01:31:02 AM »
Bought an MPC with a broken encoder according the previous owner
bought a new one same problem then got an replacement from the seller, same problem.

So I suspect that the MPC is not register the encoder correct
I tried with a encoder with less detents and that worked
so I reckon that MPC is sensitive to how narrow the pulse width is from the encoder,
not sure i'm definitely not an switch encoder-pro.

Any idea where to start to look?
the 5v is good, and both legs on the encoder have it thru the 4k7 resistors

Attached schematic.
