That seems to be the popular choice, which is not unexpected on the=20
piclist :)

I'm using internal oscillators, so it's probably better for me to use=20
something other than UART.  I'll probably just reuse code from a varying=20
duty-cycle protocol I've used a few times before, where 33% & 67%=20
represent 0 & 1 respectively.  It's very forgiving of timing variances.

Cheers,
