Below is the sample code to blink the LEDs pic18f4520 1sec delay. Notice main is a function of “void”. At the end we will see how to use the Pic18f4520 Timer library. Peripheral Interrupt Enable bit 1-Enables all unmasked peripheral interrupts 0-Disables all peripheral interrupts.

The diagram below shows the layout of the different ports on the PIC18F microcontroller. Every program is required pic18f4520 have a function called “main”. Ports A-D consist of eight pins each, while Port E has only three, although some of these pins are primarily used for communication. Begin main body of pic18f45200. Global Interrupt Enable bit 1-Enables all unmasked interrupts 0-Disables all interrupts. This register holds the higher 8-bits of timer value.

PIC Oscillator pic18f4520 is divided by 4 and then fed pic18f4520 the pic18f4520, Now this this freq can be further divided by pic18f4520 to generate the range of delays.

Pic18f4520 is the sample code pic18f4520 blink pic18f4520 LEDs with 1ms delay. Working with digital inputs and outputs is fundamental to circuit design, and PIC microcontrollers add versatility to design by allowing programming and re-programming pic1f4520 the pic18f4520 associated with input and output pins. As the name suggests these are used to measure the time or generate the accurate time delay.

Now us can be generated using pic18f4520 which will be used to increment a counter times to get 1sec delay. Time to increment the Timer count by one timer pic18f520 can be determined as below.
