Thank-you!!! That makes a whole-lotta-sense now Henrik!
It is finally "registering" with me. (pun intended)
I can see how PBP commands do much of the grunt work in getting the ADC paramteres to funtion correctly.
Yes, once I changed to 8-bit ADC, my code is now working flawlessly. I can now code to a deeper degree with this understanding.
Again...THANKS!!!!
