Hi Andre 1 - It appears your interrupt goes to ADSERVICE: but returns through PULL. Shouldn't your interrupt go to PUSH and then do a 'goto PULL' if it is not the A/D interrupt 2 - Wouldn't it be easier to have the A/D interrupt routine restart the A/D conversion cycle? Maybe not relevant if the PIC is doing other things as well. 3 - doing andlw 0x7 will give you the least significant bits from the A/D. If you want the most significant bits you will need to do some more work maybe, rrf ADRES,F swap ADRES,W andlw 7 call TABLE It looks interesting and quite easy to expand to 16 LEDs.
