How Does The Watch Count Steps

[voloved]

Hello,

I see the Bangle 2 uses a KX023, but I see that the KX023 doesn't have an integrated step counter.
How does the Bangle watch count steps? I couldn't find the code that would perform that function. If it's public, can it be shaed with me (and sorry if I missed it when searching).

The purpose is that I'm trying to add step counting to the Sensorwatch project and I'd want to see how other open-source watch projects solve this puzzle.

Hi! It's all in the Espruino repository - the step counter is at https://github.com/espruino/Espruino/blob/master/libs/misc/stepcount.c

Yes, as shown in the file @gfwilliams pasted, it basically just smooths the values, and finds a spike in the accelerometer data that it compares against thresholds to determine if a step was taken or not.
