1.3 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 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.
