Do not call Wire.begin inside the sensor.begin about sensorlib

@dizcza
would you mind to try teaching Adafruit to write their libraries first ?

I would if I used their lib. Is it a dependency?

This library was originally designed to be used by ESP32. ESP32 originally has the ability to prevent repeated initialization processing. If the user initializes the Wire externally, the Wire first used by the first user will be used.

As a matter of fact, I did open an issue on Adafruit.

This library was originally designed to be used by ESP32.

So I cannot use it for non-esp32 boards? It looks like I can... except that I don't know how, for instance, SMT32 handles the issue of repeated Wire initialization.

You rely on the implementation-specific behavior of underlying firmware functionality. I know that others do exactly what you've described. Well, as long as it works.

A short question. Does QMI8658 output accelerometer values in m/s^2 and gyroscope in degrees per second?

[lewisxhe]

yes
