Hey guys. I'm a new user to ccs compiler.
I'm trying to decipher how the following functions are set up:

Code:

read_adc(), setup_adc(), setup_adc_ports()

could some post the actual routines(codes) for the above functions for me to help me cross check the set-ips from the data sheet.

Make a test program with those functions and compile it.
Then look at the .LST file, which is in the project directory.
You'll see the ASM code used by the compiler for those functions.

Thanks alot programmer.The reason why i'm looking specifically for the above functions is to help me figure out how they are set up in C programming so that i can be able to see if i can apply the concept to other components of the PIC IC/device.

Code:

read_adc(), setup_adc(), setup_adc_ports()

Please kindly post them...
thanks in advance..
Very Happy

CCS doesn't give the C source for those functions.

Examples of analyzing the .LST file, to see what the CCS A/D functions do:
