Thanks for the suggestion. The quadrature encoding system looks really cool.
For me right now, I've already got all of these events happening on the PRU, and I just need to measure the time between them so a simple counter is what I am after... and I've found one, so I will use it. But I am still confused... Why is it the DMTIMER2 running and not all of the others? Why am I not able to access the registers of the other timers using devmem2? Is there some other process that is using DMTIMER2 that I should be aware of? Timers are being called out in cape-universal, and then show up in /sys/devices/ocp.3/ but how do I make use of them? Answers to any of these questions would be super helpful! Thank you, Bill On Tue, Feb 3, 2015 at 7:35 AM, TJF <jeli.freih...@gmail.com> wrote: > When this is your aim > > Am Montag, 2.
