I think this is what you're after: logDate: function(n) { let month = n & 0x0f; /* bits 0 to 3 */ let day = (n >> 4) & 0x1f; /* bits 4 to 8 */ let year = 2000 + ((n >> 9) & 0x7f); /* bits 9 to 13 (15); epoch is 2000 */ return day + "/" + month + "/" + year; }, From https://github.com/ergarcade/pm5-d...

Hi Citroen, Your mistake it to assume that the way (k)calories are measured on the PM5 bears any relationship to the way (k)calories are calculated in the real world and by any other sports equipment. The chart displays the same thing as what is displayed on the monitor. It doesn't make any attempt ...

Hi Allan, The calorie calculation is not the same as used by the PM. At pace 1:40, the difference is almost 300 kcal/hour. I recorded this video of rowing for 1:00 at 2:00, 1:50 and 1:40. The monitor shows pace, ErgData shows cal/hour. Matching paces onto the chart shows the same cal/hour value - 2:...

Thanks for picking that up. I was originally working on the BikeErg numbers so pace is off for SkiErg and rower. Fixed now.

I quickly put together an interactive chart mapping pace, power, cal/hour and speed for Concept2 ergometers. These are the same values you see on the erg monitor. Having them all overlaid in a single chart might be useful when planning how to attack a workout. https://ergarcade.com/articles/c2-pace-...

Thanks for the link, its a wealth of good detail. I am wondering if the raspberry pi zero and the approach that I am using isn't fast enough to get the data. It currently issues a usb command (in python), waits for the response and repeats. From the comments in your code, it looks like you "poll" b...

I ran into similar when I was working on a PM proxy over USB a while back. Have a look at this code around line 454 . If I remember correctly there are a few ambiguous edge cases. If you are interested in the BLE interface I’ve done some work; check out www.ergarcade.com. All code is available on gi...

For more browser-based solutions checkout Erg Arcade. The pm5-base sample application abstracts away all the comms so your app can just receive information from the monitor. Code available at GitHub.

Utility to dump all PM5 BLE variables as JSON. Useful as a way to generate input files for replaying when developing applications.

Sure, go ahead.

A system-tray application that acts as a proxy using USB between PM3/4/5s. Data collected can be passed to third-party applications via WebSocket . Implements most of the CSAFE and Concept2 specific commands. Requires Qt. Tested only on Mac OS X with a few PM5s simultaneously. https://github.com/erg...

A small browser application for viewing all PM5 variables available over Bluetooth. Quite easy to hook in your own browser applications. Uses web bluetooth and only available in Chrome. Tested on Mac OS X.
