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
