I'd prefer not to use the mesa encoder primarily because I want to use the optical isolation I already have on the 7i37. Additionally with the firmware setup I have (4 pwm, 4 encoders, 4 stepgens) and the 3rd 50 pin cable for io like estop and limit I only have one Mesa-based encoder available with no optical isolation. Ideally I'd like to run multiple analog inputs.
Although if I go the weighted sum route I'd be limited by my io as well. It seem I must be doing something wrong with the software encoder though, as i think it should easily be keeping up with the frequencies I'm sending, Thanks, Scott On Mar 15, 2012, at 2:50 AM, Viesturs Lācis <viesturs.la...@gmail.com> wrote: > 2012/3/15 Scott Hasse <scott.ha...@gmail.com>: >> with the frequency out going to an isolated I/O daughter >> card input (Mesa 7i37 I believe) of a Mesa 5i23.
