 If you have a Garmin watch, they are using this fit file format, ChageBt seemed to know a lot about it. So it was able to generate a file that loads a fit file from a Garmin watch. It's just an old example from GitHub from about seven years ago. So it must be a very old watch. It's actually two major libraries for passing those fit files. So it's able to extract what's in the header, but the header looks a bit weird. So we have a header length of 12. However, we're only showing four records. I don't know why. So we have to fix that. And I don't know if there is any interest in doing this, but we will try and display the data. The interesting thing, I don't think all the watches have a PPG data in them. So that's the main one I'm after. I want to see if it's a textbook PPG like. Yes, we'll have the heart rate temperature. It should have accelerometer data. Apparently the sampling rate is not determined like in the standalone number. Supposedly each PowerPoint has its own time stamp. So we'll see how that works. So it's suggested some more functions, but they have a placeholders in them. It's getting a bit confused with something. Anyway, the header is there. I don't know. Should we spend more time on this considering it's a very old file from about seven years ago. So if you have any newer data files, if you know that your device has recording PPG, it's the blood oxygenation level oximetry. Then ideally just pop your data on to GitHub. So anyone including myself can have a quick look. Just move on to other things that we're doing. So the last published tools is the eG2 music converter. If you tried it out, if you haven't tried it yet, please do so. Let me know what you think. There is also the music from hand gestures.
