I'm not sure if the index HAL pin is supposed to be a copy of the hardware index pin or not - that pin isn't part of the canonical encoder interface and does whatever the driver writer had in mind a the time. The index-enable HAL pin is bidirectional - you need to set it true, then the driver will set it false (and reset the counter) on the next index pulse. If index-enable is false, the driver does nothing at all when it sees an index pulse. > The pulse shows as about 2 mS wide at 4 ipm so it is there.
