C code to energize relay on PIC16F887 at startup, de-energize after preset time

Hi! i need a C program 4 interfacing a Relay with PIC16F887 Microcontroler, when initializing the Microcontroler, the relay should be energised hence closing the Normally open contacts, an should be De-energized after a peset time duration. Plz help.

Hi need some circuits first and a basic flow chart of what you want this to do. Eg Time delay, when this should open or close I.e time to stay open, time to stay closed, time period as to when relay operation should begin Is it switch operated Should it be operated from start I.e init period Voltage rating of coil current etc etc etc

YOU MUST HAVE SOME PLAN OR FINAL GOAL AS TO WHAT YOU WANT TO ACHIEVE MORE IMPORTANTLY HOW YOU INTEND TO REACH THAT STAGE BEFORE YOU WRITE SOFTWARE
