Hi all,
I'm having problem to use the porta.4 as the analog input for PIC16F88... When i connect the signal line (0.1v to 0.9v) to porta.4, the signal voltage will become 0v. I have tried to put a 10M series resistor to porta.4 and connect another 10M resistor to the ground. Anyone have the idea?
I also tried to connect the signal line to other AN, for example AN2. Now the voltage on the signal will be .2 lesser than the original voltage. I really don't have any idea on this. Please help!!
Thanks!
