Most of the ADC's i've worked with were independant, and could easily be identified as problematic, with this ADC on board, its a crap shoot of is it really noise I'm picking up on the board, or is there some kind of coding error on my part. There is no way to sample the or verify the bits on the ADC but only to see if the function is actually working.

I'm relatively new to this Philips MPU, so I'm kind of grasping at straws as to what could be going on. I only know that my device is "hunting" for it target, yet there is very littel noise on the wiper arm of the pot according to the scope, typically not enough to cause the major deviation I'm seeing on the device.

So that leads me to believe their is something going on in the code or the way the MPU is sampling based on changing the GPIO for every program cycle interation around each function.

I can cut the samples back to 5 and 9 if it will work.

And to Russ.....I search "C" "8051" "bubble sort" "insertion sorting" google....almost nothing comes back......or anything that makes sense anyways.
