So do you want to keep the error a secret?

 

PANEL_ANSEL_ANS_BIT = 1;

BATTERY_ANSEL_ANS_BIT = 1;

Are these two lines of code that you gave me that are causing error in the compilation.

 

If you are using XC8, you could also use the XC8 ADC functions found in the PIC18 Peripheral LibraryHelp Document

 

PANEL_ANSEL_ANS_BIT = 1;

BATTERY_ANSEL_ANS_BIT = 1;

Are these two lines of code that you gave me that are causing error in the compilation.

Did you define them? And are they configured to your hardware?

#define PANEL_TRIS TRISCbits.TRISC0
#define PANEL_ANSEL_ANS_BIT ANSELbits.ANS4

I just posted some example code. You are going to have to do some work in configuring it to work with your chip.
