Force curves for multiple ergs

[Steve Conner]

Hi all
Is there a way to display force curves for 2, 4 or 8 ergs all together on the same screen? We often train as a crew on slides in the winter and it would be really interesting for everyone to be able to see each other's curves and how well they match.

I have plenty of software development experience but am not really sure where to start.

Can it be done with the serial wiring used by the Venue Race app, or does it need to be USB?

Is it possible to synchronise the curves, so for example if someone was catching later, the curve would appear displaced to the right? Or is there some trigger inside each machine that determines where the start of the curve is?

Thanks
Steve
