Can confirm this is running on my system too, nice!

Regarding the calibration part, I read the section about that here ([GitHub - QuantAsylum/QA40x\_BareMetal](https://github.com/QuantAsylum/QA40x_BareMetal)) and the source code comments. Do you have a routine to determine the calibration constant for a device or is this magic number constant enough for all units?
