This post provides the LED blinking code (compiled in MPLAB + HI-TECH C) for PIC18F452. Complete project code and the proteus simulation can be downloaded from the Downloads section at the bottom of this post. The following diagram shows the required circuit.
In this project a crystal of 10MHz is used with PIC18F452. This crystal frequency is fed into PLL of PIC18F452, which boosts it to 40MHz. As we know that any PIC micro controller has an architecture which executes an instruction in 4 CPU cycles, hence this 10Mhz crystal + PLL makes this PIC run at 10MIPS (Million of instructions per second). The code for this project is shown below.
The code was compiled in MPLAB v8.76 with HI-TECH C and simulation was made in Proteus v7.7.
