Ok, my program compiled succesfully now. It might be a part of my problem, but not everything. It is stil not working. At this moment it only reads a 0 (zero). At least, that is what my program prints ...

I tried this as well:
ADFM_BIT = 1; // Right justify the A/D result
and this is a copy past from the other post. When I did this the following error occurs:
Error[12] MAIN.C 82 : Undefined ident ...

Ok I tried this:

0x9F= 0x9F | 0x80; // this sets the ADFM bit

but now i get this error message:
Error
#NOLIST // Provided units

Well I expect to see a number between 0-1024 corresponding to the voltage which I can measure at the input of the AN0/AN1 to appear at the lcd screen.

The input is now connected to a powersupply (a ...

Ok, I changed the program following your directions.
The output to the lcd did not change except that the values are now alway 32 or 160.
I don't know if you can do anything with those values, but . ...

2. I am measuring a DC power. It might change a bit, but at this moment not. (I will think of this for my fnal design)

3. I made an error in the pos ...
