I am Emmanuel from France.
I use RTIMUlib. on a chines mpu9250 board without problem.
I just bought the drotek version and I have some overflow on magnetometer reading when I move the board on a 8 pattern (for calibration purpose) please look at that (this is a Serial.Println output=
after that ovf never go out…
if I dont move the board this never happen!
This is very strange because if I put my other chinese board, this never occur!
Anybody have an idea of what happen?? (I search long time on Internet…without success)
Hope somebody could help…
