Hello Phil,
I would be very glad to see these drivers.

interfacing
Using one of the spare EP930x timers, I am
actually getting quite
reliable and accurate timing for sampling signals
at a rate of
~5.3kS/s. Also, although I haven't had a chance to
test, I am hoping
that I will be able to do this across multiple
channels (up to 6
channels, giving ~32kS/s total).
Which reminds me, I was going to see if anyone was
interested in the
drivers that I have written for ADC sampling?
Probably not terribly
robust yet, since I only have the one board to play
with at the
moment, but could be useful nonetheless. Let me
know if you are and
I will post them.
Cheers
Phil
