Arduino EEPROM Read/Write

This is an implementation for reading/writing IP related information (IP Address, Subnet, Gateway and DNS) from/to Arduino EEPROM. Tested on Arduino Ethernet board which has 1k of EEPROM but can be adapted to other Arduino boards.

API Structure:

COMMAND:PARAM:VALUE

Available serial API:

• WRITE:IP:192.168.1.50
• WRITE:SUBNET:255.255.255.0
• WRITE:GATEWAY:192.168.1.254
• WRITE:DNS:192.168.1.254
• READ:IP
• READ:SUBNET
• READ:GATEWAY
• READ:DNS
• RESTART:NET

Assigned EEPROM Addresses:

• IP : 0-3
• SUBNET : 4-7
• GATEWAY : 8-11
• DNS : 12-15

Example:

<< Serial port COM6 opened
>> READ:IP
<< IP : 192.168.1.100
>> WRITE:IP:192.168.1.50
<< WRITE OK
>> RESTART:NET
<< RESTART OK
>> READ:IP
<< IP : 192.168.1.50
