mapping PWM to other DIO

Hi Kevin,

As far as I know there is no such possibility. The closest you could do is generating interrupts at the respective edges and set/clear the other GPIO's. But this is not a real clone of the "Master" PWM.

Thanks for the reply, are you aware of any extra penalties that would be incurred (speed?) for operating in this fashion? Has anyone tried this and know of any pitfalls - i.e. duty time becoming inaccurate? If its a "ting" < few ns in uptime and down time - I could probably live with it (as long as its constant....any thoughts?

Kevin,

The main delay would be the interrupt latency you face. Depending on your interrupt setup (nested or not) this can vary. I would expect it t be sub 1us but check it. Whether the latency is constant or not depends mainly on the number of interrupts you have in your system. The more you have the more difficult it is to have a constant latency for the specific interrupt. I've never implemented a similar thing, but in your case I would give it a try.

Thanks for this (I've not seen it before).  Am I right to see at first glance I can use the APWM to provide an addtional 6 PWM lines (with phase control?)

Yes, you are correct on this,

The document i referenced above has all the necessary details,
