What is difference between test program and driver ?

Could someone help me ? Am a beginner with CCS, I don't see the difference between the test program and and the driver code. What should I put in the PICC to compile ?

Hi,

They are both required. The "driver" contains functions that directly read and write to the external hardware (in this case an RTC), and the "test program" contains calls to these functions, and display routines to output the data.

I use the command line version of the PCM compiler with MPLAB IDE. I would create a working program using this code by placing both files inside the same directory, and then compiling the test program using the CCS compiler. It will automatically find the driver file (notice that it's referenced in the test program), and do everything necessary to make the block of code you would program into your PIC.
