    hex not working on hardware, while in the simulation, the result is okay.

    hi, i have a problem. i have written a simple code in C to make an LED blinking. after compiling, using the MPLAB Hi Tec PIC Compiler, i try the hex file with simulation, the result was okay. but when burn into PIC, it seems like nothing happened.
