read_adc();help
PostPosted: Thu Sep 09, 2010 8:16 am     Reply with quote
Hello everybody,
I'm trying to program a pic16f877 and I need to use the adc on AN0(RA0) but when I try reading the adc using read_adc(); function, the program blocks there. It seems to be in a never ending loop.

And the fuses and CCS version info.

Make sure we can compile what you post and it exhibits the fault you have stated.

Yes.
The only time I have seen somebody manage to hang read_adc, was where it was being used without a setup_adc line, so no clock was selected....

Best Wishes
