calibration in imu #127

Hi, do we need to calibrate the sensor icm-20948 or DMP is automatically do this if we rotate the sensor in all direction during power on? or we have to make some changes in the code for the calibration.

Hi,

To calibrate the DMP: start the DMP; rotate the sensor around all three axes; and hold it stationary in all six orientations for a few seconds.

Best wishes, Paul

OK DMP automatically calibrate the sensor when we turn it on and rotate it in all direction but Without DMP how to calibrate ICM-20948?

You will need to do that using the normal IMU techniques. See: https://thecavepearlproject.org/2015/05/22/calibrating-any-compass-or-accelerometer-for-arduino/
