A PWM question

Objection ...

an asm interrupt can stop it ... but with an external action ! ( also possible with a timer ... but what the real use ? )

Hi Acetronics,

I want to output a pulse train to a stepper driver controller to turn a rotary table. If I make a mistake in entry or part way through the router cut I want to stop it. I realize I can just turn it off but wanted something different.

Thanks, Don

Timmer interrupt, HPWM would work. A huge "safety Break" button in serie is never a bad idea in case the driver goes nuts. Current read from the motor, feed into the pic and all plah plah is also a nice extra... Even better if you keep track of every "events" around...
