| Seems an odd way to do it, but I read that EMC supports that yesterday | looking for something else. I recall wondering at the time "why?" and | now I know. | Stepgen mode 1, IIRC Another reason to use quadrature over step and direction is speed. When switching directions a quadrature interface can reverse in one thread period, while the step/direction requires two thread periods for a single step pulse and one for the direction pin (unless you do fancy stuff with it). ------------------------------------------------------------------------------ Come build with us!
