RF Module interfacing with PIC

[Chullaa]

HI
I am willing to interface RF module TRW-24G with PIC16F877A. I am using CCS C complier.
Can any one suggest simple code or tutorial. will it use SPI port?
I have successfully done UART wired communication.

Thank you
Umair

this is the sample code i googled from **broken link removed**
if u have any doubts regarding this u can get it from the above data sheet

I am trying to understand the code. I have seen some codes that use SPI or UART to interface TRW-24G, I could not figure out which one is this. or this is other method.

Thanks
