It was brought to my attention that I should probably have termination resistors on the differential encoder inputs. While it was fine in testing, after doing some research I'd have to agree. I slapped some pdf schematics in there as well. Also improved the differential signal routing.

However, It would probably be a good case for looking at the possible issues with Smart serial in MK/mksocfpga. The Mesa 7i83 would probably be a painless solution for analog servos, and a better setup because you can put the 7i83 in it's own shielded case and keep the analog stuff away from the rest of it and the only thing between the 2 is a chopped up ethernet cable. I just ordered a 7i66-8 that I'll pass on to Michael if that fares the same as my 8i20 (discovery happens then faults out and drops comm.) Hopefully mksocfpga will get a little more traction, there's some really good use cases for it. From an all in one HMI type deal to what I think would be a pretty capable remote machine control setup. -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
