Displaying values retrieved from a munin node on an RS display board. Porting this code to work with an alternative display should be trivial, I have also used an mbed application board's LCD to display the values for example.

Hardware

Software

Most of the work is done by libraries that are freely available on mbed.org. The code uses the lwip based EthernetInterface library. The only code I had to write was submit a command to a munin node and parse it's response.

Testing

The software has currently been running for around 2 weeks without any problems. On a previous run it stopped updating after 4 days.
