Project Summary In this project we are building a JDM programmer that can handle PIC12, PIC16 and PIC18 family microcontrollers and some popular 24C family EEPROMs. The programmer also provides ICSP feature that allows In-Circuit Serial Programming. So if you desire, you will not have to carry your MCU each time when you reprogram it. […]

In this project “Interfacing external EEPROM with PIC Microcontroller”, we will see how we can easily interface EEPROM via I2C Protocol. The need of external EEPROM as a permanent storage of data in any project is enhanced. So now question how to interface external EEPROM with PIC Microcontroller? Project description: In this project “Interfacing external

Saving Data using EEPROM in PIC16F877A In this tutorial we will learn how easy it is to save data using the EEPROM present in the PIC16F877A Microcontroller. In most real time projects we might have to save some data which should not be erased even when the power is turned off. This might sound like
