Hi,
i'm new to PICs and am trying to use the AN0 port on a 16F877 to read a voltage ~1 volt from an external device using an Microchip X1 board. I have a program that works reading the voltage (0-5)through one of the on board variable resistors but when I put my voltage from the external device on that pin I get nothing. I'm taking the ground from the external device also but no joy. Can anyone help?
Thanks.
