Hi Charles, I don't understand exactly what do you mean here: *More encoders could be supported if you used a single GPIO bank and did one GPIO read with the PRU each loop of the encoder logic. This adds about 160 nS to the loop time, but if the PRU isn't doing much else you should still

Hi Charles, I am studying the possibilities of having 3 axes with step/dir and encoder signals A/B/I to control servos. It's a shame about the eQEP1, I saw the pin overlapping too :( I have followed your work with PRU's and I'll try by this way. I think it is possible to use the PRU0 for 9
