Hey Guys:
Thanks for pointing out my errors. Yeah, I thought I had 512k or ram for programs. I thought I had a lot of program space to allow for a decent number of samples to average things out. Don't forget I was expecting at least 100's of thousands of samps/sec and thought that my u sec counts might come in the single or double digits. Either way. I reduced the array size to 1000 and got the same sample rate 25,168. Why my programing was not seg faulting ... Well, I'm just ignorant. Either way, after taking your points into the equation, the outcome is the same. A rather slow A/D.
Thank You.
