The Sigma ROX is one of those fancy bike computers where the performance data can be analyzed later on a PC. Although Sigma developed their application for using it in Adobe AIR, they don't provide a Linux port. There are some tools available like SportsTracker, BikeXperience and GoldenCheetah which are able to look at the data files. Unfortunately they couldn't download the data directly from the Sigma ROX, because the serial protocol isn't public. That's why I've implemented the serial protocol and "rox_sigma" is the result.
Now download the code, read the included howto.txt and bug me with questions if you have any problems. :)
You want to write some code for rox_sigma? Please get the latest development tree first with mercurial from my repository.
