# circuitpython-at24mac-eeprom

Driver to interface with AT24MAC402 and AT24MAC602 devices using I2C

## Usage

the AT24MACx02 devices are EEPROM devices with a built-in MAC address. 

```python

import at24mac

import board

i2c = busio.I2C(board.SCL, board.SDA)

eeprom = at24mac_eeprom.AT24MAC(i2c)

print(eeprom.mac)  # Format for use with Wiznet5k

print([hex(val) for val in eeprom.mac])  # Readable format

print(eeprom.serial_number)

print()

# Write and read to address 0 

eeprom[0] = 76

print(eeprom[0])

print()

# Write and read to address 100-104

eeprom[100] = [6, 7, 8, 9, 10]

print([val for val in eeprom[100:105]])

print()

```
