I suggest that you start with the CCS example, Ex_Slave.c.
Here's the file location:
c:\program files\picc\examples\ex_slave.c

Here's some simple master code in this post, which sends a single
character to a PIC running Ex_Slave.c, and then reads it back.

Remember that you need pullup resistors (4.7K will work) on SDA
and SCL, and you need a ground connection between the two boards.
