And mine turning a harmonic drive. I'm using the step/direction interface.
Except now that I've wired it into my

Hardware driver ( IRAM256-2067-A2 ). The software side of things works
really well.

It is a problem that has been solved by the STMBL servo drive project.

Hi Rudy
I know this is a while back, but
I now realize that the A phase cannot go through the counter in the firmware
of the 6i25+7i77 setup and then read serial data.
Would it be easier to use a 5i20 + 7i33 combination. Then modify the
firmware so under some control input bit the A phase is first passed through
by-passing the counter,
