# 1.2 EEPROM Emulator Library Read Write

This application example demonstrates how to read and write to the Emulated EEPROM memory space using the EEPROM Emulator library.

## Description

This example uses EEPROM Emulator library to read and write to the NVM Emulated EEPROM memory space. The application first checks if the library was initialized successfully or not. When running the application for the first time, the EEPROM Emulator memory space will be formatted by the application. The application then writes data to EEPROM memory space using the APIs provided by the EEPROM Emulator library and then reads the data back and compares it with the written data.

## Downloading and Building the Application

### Setting Up PIC32MK MCJ Curiosity Pro Development Board

- Connect micro USB cable to the Debug USB connector (J1) on the board to the computer. This will enumerate as a COM port on the PC.

### Setting Up PIC32MK MCM Curiosity Pro Development Board

- Connect a micro USB cable to the USB DEBUG port J500
- Connect a micro USB cable to the USB to UART port J400. This will enumerate as a COM port on the PC.

### Setting Up PIC32MK MCA Curiosity Pro Development Board

- Connect micro USB cable to the Debug USB connector (J1) on the board to the computer. This will enumerate as a COM port on the PC.

## Running the Application

1. Build and program the application using its IDE.
2. LED indicates success or failure:
   - The LED is turned ON when the value read from the Emulated EEPROM memory region matches with the written value

Refer to the following table for LED name:

Board | LED Name
--- | ---
PIC32MK MCJ Curiosity Pro Development Board | LED1
PIC32MK MCM Curiosity Pro Development Board | LED1
PIC32MK MCA Curiosity Pro Development Board | LED1
