Success! I just finished the Concept 2 rowing machine API wrapper. It has been 90% complete for many weeks.
I was being held up by the fact that you can not directly read the target time for a fixed duration piece nor the number of meters for a fixed distance piece from the PM3. These values have to be calculated before the start of the row based on other factors. I wasn’t sure how best to calculate the time remaining and meters remaining. In the end, I just went with a calculation that is based off the piece so far coupled with the instantaneous split. This means the estimate will jump around a bit, but has the advantage of giving rapid feedback to the rower as she pulls harder. Rowers out there, would this bother you?
This is a screen-shot of the wrapper demo:
It is pretty ugly. I had started to use pyFltk for the demo GUI, which looks very nice, but this would require installation of another package to run the demo. Instead I coded it in Tkinter, which comes with python and requires no extra installation.

Hi
Is your PM3 API python GUI demo program available for download? I’d be interested to give it a go.
Cheers

Simon, Thanks for your interest. I’m working on a program that will connect to the concept 2. I hope to have it available by mid-Novemeber.
