No, is not a modified example file.

I think you have to unzip the files to a folder.

I've tried it and it works.

Hope u can help me out.

Thanks a lot.

Have you built this circuit and do you have it working now for a single channel on RA0?

Ya, I've constructed it with single channel on the breadboard but i haven't try it out yet.

But my friend tried it before, he said it's working.

Thanks.

There shouldn't be much to this. The PIC multiplexes the ADC inputs so all you have to do is loop over each input and convert each one, and display the result in the same way the first is displayed, except obviously at a different part of the screen. Where exactly are you stuck?
