EepromShim 1.0.0

A unified EEPROM wrapper library for Arduino boards providing seamless compatibility between AVR (built-in EEPROM) and SAMD51 (QSPI Flash) platforms.

Features

• Unified EEPROM Interface - Same API works across AVR and SAMD51 platforms automatically
• Smart Backend Selection - Uses built-in EEPROM on AVR boards, QSPI flash on SAMD51 boards
• Full API Compatibility - Drop-in replacement for standard Arduino EEPROM library
• Template Functions - Type-safe get<T>() and put<T>() functions for structured data
• Configuration Management - Advanced configuration storage with versioning and validation

Installation

1. Download the library from the releases page
2. Extract to your Arduino libraries directory
3. Include in your sketch: #include <EepromShim.h>

Quick Start

#include <EepromShim.h>

void setup() {
    Serial.begin(115200);
    EepromShim::init();  // Initialize EEPROM/Flash

    // Write a value
    int myValue = 42;
    EepromShim::put(0, myValue);

    // Read it back
    int readValue;
    EepromShim::get(0, readValue);
    Serial.println(readValue);  // Prints: 42
}

void loop() {
    // Your code here
}

Examples Included

• BasicEeprom - Simple read/write operations demonstration
• ConfigExample - Basic configuration storage using simple data types

Access via Arduino IDE: File → Examples → EepromShim
