Are you sure that you don't have AN0 as output ? What is on output if you set "1" in your program ? Still 80mV ?Giftbox said:I have added voltage follower to the my circuit but still not work
Hi,Giftbox said:I use PIC16F877 which has on chip 10 bit ADC.I have the problem when I use ADC measuring voltage 0-30V.
I have tried to use voltage divider but not work.
