<p>Hi Euan</p>
<p>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 :-)</p>
<p> 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.</p>
<p>All the best<br>
Harry <br>

Euan! Inspired by the last round of tally lights... Harry's
made some<br>
new PIC-based protoypes. Do you still have the source to
the AVR ones?<br>

Haven't rebuilt the code yet, but reloaded some of the
pre-built images<br>
a couple of times.<br>
<br>
Current protocol follows for the:<br>
uber_tally/src/PIC16F1-USB-Bootloader/sample_app/usb_rgb.hex<br>
