Hi Jeff,

Looking at your results, it seems like your pic is stuck on channel zero even if you're reading channel one. A redaing of 800 vould represent around 3.9V, just what you should have on channel zero(7.8/2=3.9).

Either you have a short beetween theese two pins on your board, or it might be a miss/bug in PBP. Looking at the datasheet i see that the 16F88 uses slightly different bits in the registers controlling the A/D converter than most other pics. I only have V2.44 which doesn't support 16F88 so i can't check, but it just might be that they missed this at MeLabs.

Look for a short and if there is none you should try stuffing the A/D controlling registers manually and see how that goes.
