Hi Rich,
Thank you very much for your help, I'm looking forward to trying to build my ADC driver in Tiny Core 3, and ultimately (hopefully) get my data acquisition software running as well. Although, for the latter, there are "real-time" elements involved as well, so not sure yet how that may work out, but I'm encouraged to see that there are real-time "patches" for TinyCore too, hopefully it will all work out !
Thanks again for all your help.
Cheers,
David
