Why does the ABI encoder does not work on my VESC Pronto?
All Pronto-controllers shipped until 2026-03-15 have a hardware bug for the ABI encoder input, where the A and I signals are swapped. This can be resolved by swapping the A and I cables on the encoder. If the PCB is green it has this bug. PCBs shipped from late March and onward are black and do not have this bug – on them the ABI encoder can be connected normally.
