I am now doubting myself and expect I am missing something that is glaringly obvious but >From the Pickit2 Output Window "Programming Target (3/01/2013 4:40:25 PM)PIC16F887 found (Rev 0x2)" I am reading this manual "PIC16F882/883/884/886/887Data Sheet" The manual clearly refers to ANSEL FIGURE 2-6: PIC16F886/PIC16F887 SPECIAL FUNCTION REGISTERS Mentions "ANSEL 188h" and "ANSELH 189h" and "ADCON0 1Fh" and "ADCON1 9Fh" So I understand in summary that ANSEL and ANSELH determine if the corresponding pin is analog and ADCON0 CHS3-0 determine which pin is *connected* for conversion purposes. What have I missed. Cheers justin --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
