That wouldn't be my first choice. I use the PICs for a lot of things but they are generally fairly slow. Maybe a DSPIC. For motor control I use the TI 2800 series. Then again I am doing very accurate brushless DC motors with a DSP loop of 30 KHZ. To just do the control on two PWMs for an H bridge controller you could easily do it with a PIC. jv -- Blog: http://volcano.newts.org
