I'm afraid I don't have the patience to apply the necessary brain cells to the hermeneutics of the ATMEGA manual right now. My only advice is to put it all down for a day or two and then re-read _every_ section of the manual that might apply, looking for some small detail that got buried in the text.
From your previous messages it sounds like you've gotten each individual function you want working, so I would pay special attention to any section of the manual that discusses the interactions between counter/timer components. If you are graphically oriented, tracing through the schematic diagram of the counter might be helpful too. sorry MS sofia aparicio wrote: > Hello, > > I would like to configure in Fast PWM mode without prescaler and > toggling OCR3A,OCR3B and OCR3C at the same time.
