Hi,

Is there any examples of using an AVR as a SMPS controller for a flyback or forward converter. If so which models are preferred for such an application.

May want to have a look at "AVR450: Battery Charger for SLA, NiCd, NiMH and Li-Ion Batteries" that's the only one I know of, there may be others.

Thanks, that will do as a start on the issues involved.

One question, is it possible to synchronize two or more AVRs together, to prevent the production of beat frequencies from them running at slightly different speeds?

You can clock one with the other.

No RSTDISBL, no fun!

Assuming the two MCU's are reset with the same reset signal, whilst they should be synchronized , I wonder, whether there will be a phase difference and if so how large? Something to check when I have some time. :)

As long as they are not disturbed by external sources (delay for button presses etc, variations in interrupt times) they could stay in sinc forever...

Agreed!

About an hour, to satisfy my curiosity! It would probably give some insight into why the parallel programming would be iffy.
