Hi All,

I am pleased to report that I have resolved this problem
I had omitted setting up the ADCON2 register
Code:
ADCON2 = %00001111
I also needed to set the output format to Sign-Magnitude and then shift the result six places to the right to achieve right justified result
Code:
ADCIN 0, Adval1
Adval1 = Adval1 >> 6
Hopefully this post may help someone in the future.

Cheers
Barry
