One possible reason is that you are not turning off the comparator and = ADC of 12F675. Make sure your PBP code has the following two lines in the = beginning: CMCON =3D 7 'Disable comparator ANSEL =3D 0 'Disable A to D=20 Since you are using PicBasic Pro, PicBasic (picbasic-l@qunos.net) would = be the appropriate forum to send your posts to.
