you right, it is so good,it support both variable frequency and variable pwm
i am in device selection phase,i wasn't sure dspic can fit in my application,now i'm moving to schematic phase.
i want to PID control of simple stepper motor, dspic control a micro-step drive by optical quadrature ruler feedback.
do you have any solution ? i just want to compensate any step-lose.
i can't do any change in motor or micro-step drive and need to keep system simple and cheap.
