PIC16F877 internal EEPROM code and Proteus simulation

This post provides the internal EEPROM reading and writing code for PIC16F877 microcontroller.

PIC16F877 internal EEPROM

As we know[1], PIC16F877 microcontroller has 256 x 8 bytes of built in EEPROM data space with an address range of 0x000 to 0x7FF. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page.

It is assumed that you know how to blink an LED with PIC16F877 microcontroller. If you don’t then please read this page first, before proceeding with this article.

The result of simulating the code in Proteus is shown below.

In the above circuit[2], LED attached on RB0 indicates weather a byte was successfully written in the internal EEPROM or not. In the above figure, LED is ON which indicates that EEPROM was successfully programmed.

Code

The code for the main function is shown below.
