| Many thanks, I now have sleep mode working perfectly! I still need to polish my analogue circuits but with the capacitor the results are much much better.
Again many many thanks. |

| 0.1uF capaictor now in the circuit and the stability has improved. It now sits at 8 to 9 bits accuracy. Thank you very much!
I'm not sure how to 'decouple the power supply' I'll have to read my el ... |

| I am trying to get a reasonably accurate measurment from a potentiometer. I am using a 18F4550 which in theory has 10bit ADC. The stability of the reading is 7bit at most the remaining 3 bits are cons ... | |
