EEPROM Memory-Map Viewer

Solving Approach

How do you plan to solve it?

• Loop through all EEPROM addresses.
• Print address in HEX.
• Read 16 bytes per row and print each in 2-digit hex.
• Continue until the entire EEPROM is displayed.

Code

/*Paste your code here*/
#include <EEPROM.h>

#define EEPROM_SIZE 512  // Change based on MCU (UNO=1024, Mega=4096, ESP32 user-defined)

void setup() {
  Serial.begin(9600);
  delay(1000);

  Serial.println("\n📌 EEPROM Memory Map (HEX View)");
  Serial.println("-------------------------------------");

  for (int addr = 0; addr < EEPROM_SIZE; addr += 16) {
    // Print address (4-digit hex)
    Serial.printf("%04X: ", addr);

    // Print 16 bytes per row
    for (int i = 0; i < 16; i++) {
      if (addr + i < EEPROM_SIZE) {
        uint8_t data = EEPROM.read(addr + i);
        Serial.printf("%02X ", data);
      }
    }
    Serial.println();
  }
}

void loop() {
  // nothing to do
}
