I still haven't spun any motors using it (I don't actually own anything that is step+direction!) but the initial simulation and testing is still promising. The driver has 4 step+direction channels, 14 dedicaed digital outputs, and 16 dedicated digital inputs. I'm hoping to find a way to squeeze in one PWM and one quadrature, but right now it doesn't look too promising. The pinout is similar to pluto-servo: the step/direction pins are in the same locationas the PWM up/down pins. The quadrature pins are repurposed as extra dedicated digital inputs and outputs. The source code (verilog firmware and comp driver) are in CVS.
