Announcing eos430, an EOS implementation for TI MSP430 microcontrollers

[FSFIan]

Code: https://github.com/jboecker/eos430

Documentation: http://jboecker.github.com/eos430/

 

This project allows you to use custom panels with Helios.

 

In some ways, this is still in its early stages -- only digital inputs are supported, the code is not as clean as I'd like, and the documentation is not as beginner-friendly as I'd like.

 

On the other hand, it runs the following "cheapskate panel" pretty reliably (given that I don't have the time, money, or space to build a serious simpit, I am aiming to maximize user interface improvement per buck):

 

In case someone wants to play around with it or help out with further development, allow me to point out that TI offers a suitable development board (the MSP430 Launchpad) for $4.30 :)

 

If you are implementing the EOS protocol on another architecture, take a look at eos_dispatcher.h and eos_dispatcher.c; these files implement the state machine to parse the EOS messages and should be useable on other architectures as well. IIRC, the checksum of received messages is not verified yet.
