I have no idea if that will work. There are 4 PWMs on the Arduino, though two share a timer. The Mega has 14 PWM pins though, so presumably has rather more timers and possibly more options (I have not looked) I think that means that it could be done, but you might run out of CPU calculating the phase angles and duty cycles. -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
