First read the datasheet to check the clock used for the timer, configuration & associated interrupt registers.
Second: inside the code you need to set
- Interrupt Service routine (ISR): small part assembly code you will add, actually it is one line assembly.
- set the ISR vectors
inside the main() function:
- set interrupts registers.
- set Timer register configuration (TxCON, x = 0,1,2,3 for PIC18F4550).
- write inside the ISR your application code.

Enjoy your timer Smile
