Re: Non-FRC Motor Controller?

All I'm saying is that the "DEAD_TIME" period is 2 us. Are the interrupts *that* fast? KHz, sure, but being able to control time to that resolution? They have to be either relying on the instruction speed of the processor to do a delay (noop loop) or sending a signal to a delay circuit, don't they? Or maybe I just don't have enough faith in the hardware...

I guess if the time is available on a port a tight loop with inportl or its moral equivalent could do it. The clock speed is what, a few MHz?
