[PLUG-AV] Progress on UberTally, Re: Tally SN0002 and SN0003 complete

[Harry McNally]

Hi Euan

Is the AVR doing bit-banging for the USB ? Nick spoke about this method but 
mentioning AVR piqued my interest which meant I had to look :-)

I can't see an AVR with a USB peripheral on the selection guides. In that 
respect the small 145x PICs are unusual but I stand correctable.

All the best
Harry
