How to capture force curve?

Post by roy649 » August 26th, 2019, 10:34 am

Is there any way to capture the force curve displayed by a PM5? All the pictures I've ever seen of force curves are from somebody taking a photograph of the screen, which seems sub-optimal.

Is there some sort of "screen shot" feature, or perhaps ErgData already has the curve stored, and I just need to figure out how to view it?

ErgMonitor will do it, or Chris Brett''s old spreadsheet interface. There's no ErgData setting. A reasonably effective method is to video the PM screen while you're rowing, rather than have someone take individual snaps.

Edit: Chris had written an Active X interface that may not recognize a PM5 even if you can come up with the code somewhere. If Citroen is lurking he may be able to help.

Boatcoach has a set of graphs for the force curves ... average, each quarter of the session and last stroke. You could also plot any stroke force curve yourself from the data Boatcoach can save.

The PMI stuff and the ActiveX control is here: https://github.com/DougieLawson/PMI
If I were a betting man I'd lay a pound to a penny it won't work with a PM5 (because it's never been tested).

It's probably too long since Ergmonitor was last updated for it to work with a PM5 http://www.ps-sport.net/ergmonitor.htm

The other way is roll-your-own software in python3 with https://github.com/wemakewaves/PyRow or https://github.com/kylegoetz/PyRow (which appears to be a later fork).
