I have a questions about output values for drivers MPU9250 and LSM9DS1.
Accelerometers values in both sensors is multipliers of g.
Gyroscopes values in both sensors is dps. But in drivers values conver to rps (why?).
But magnetometers is differ in these sensors. For MPU9250 values is µT and for LSM9DS1 is gauss.
In driver MPU9250:
_mx = bit_data * magnetometer_ASA;
magnetometer_ASA[i] = ((data - 128) / 256 + 1) * Magnetometer_Sensitivity_Scale_Factor;
Ok. We have a value.
But in driver LSM9DS1:
_mx = 100.0 * ((float)bit_data * mag_scale);
What is the meaning of the multiplier 100.0? By ((float)bit_data * mag_scale) we have a right value or no? This sensor have a gauss unit.
µT = 1e-6 T = 1e-2 Gs, if LSM9DS1 sensor had a unit of measurement for the µT, then it would be obvious. But this sensor have a gauss unit… Is this issue in driver?
Thank you in advance for your help.
