# AT24MAC EEPROM Arduino Library

Arduino library for the AT24MAC402/602 chip. These microchips have build in MAC address and serial number.

Memory size for both parts is 256 bytes.

Use the Arduino Library Manager to install.

## Example

Here is a simple example which shows the capabilities of the library

```cpp

#include 

uint8_t mac[6];

void setup() {

	Serial.begin(9600);

  while(!Serial);

  //Read and print MAC address

  EEPROM.readMacAddress(mac);

  Serial.print("MAC address: ");

  for(uint8_t i = 0; i < 6; i++){

    Serial.print(mac[i], HEX);

    Serial.print(" ");

  }

  Serial.println("");

  //Write 8 bytes and read them back

  for (int i = 0 ; i < 8 ; i++) {

	EEPROM.write(i, 100 + i);

  }

  for (int i = 0 ; i < 8 ; i++) {

	Serial.print("Byte ");

    Serial.print(i);

    Serial.print(": ");

    Serial.println(EEPROM.read(i));

	}

}

void loop() {

}

```
