this is a code for tx but i can't figure which code to edit so that it can transmit using nRF24L01 transceiver and c8051f120 as in it have ADC, tiltSC and alarm which i don't need.

#include <c8051f200.h> // SFR declaration

its very difficult to tell you which part of the code to exclude and which to include ... better way is to partion this code in smaller segments and examnie the effects....
 

will you be able understand more if i cut away the part i don't need as i really struggling
