Summary of PIC12F675 internal EEPROM code and Proteus simulation

This article details C language code for reading and writing data to the internal EEPROM of a PIC12F675 microcontroller using MPLAB and HI-TECH C. The 128-byte memory space is addressed from 0x00 to 0x7F. A Proteus simulation demonstrates functionality, where an LED on GP0 illuminates to confirm successful EEPROM programming.

Parts used in the PIC12F675 Internal EEPROM Project:

PIC12F675 microcontroller
LED
MPLAB v8.85 IDE
HI-TECH C v9.83 compiler
Proteus v7.10 simulator

As we know, PIC12F675 microcontroller has 128 bytes of built in EEPROM data space with an address range of 0x00 to 0x7F. 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 PIC12F675 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^[1], LED attached on GP0 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.
