Thanks for your great work on this. I was looking at doing just this type of process.

I plan to capture a series of equally timed ADCs. This data would eventually be sent to my computer. It will have a time stamp header to indicate the time of the first capture, followed by the series of ADC values, followed by a parity word. It seems you have given me just the tool I need for the task at hand. I can't wait to try it out.
Have you been shuffling through that pile of scribbled notes on my desk?

Thanks again for your contribution. I'm quite new to PICs and this forum, but it is clear from the reading I've done so far that you stand out as one of the top shelf folks here. I've learned a lot.

BTW, what about instant interrupts for the 16-bit flavors? My project requires quite a bit of RAM (more than any 14-bit PIC) and I really like what I saw reading through those threads. I even thought about trying to shoehorn them into my 18F4620, but balked. I am still quite the newbie. I know it would teach me a lot to work it out on my own, and I would enjoy the process, but I can't spare the time right now.
