@intensite Mounting Vertically... The Gyro Calibration could be done at any angle. On the other hand, the Accelerometer calibration requires gravity to be in a known direction. in order to...

@phhoef > This suits to your assumption in code, that gravity is in Z direction, right? This is correct I remove gravity from the Z direction so that the resulting...

Calibration uses gravity only to remove it. If we were in a zero g environment accelerometer calibration would work perfectly without removing gravity. the calibration offset values that are generated...

First of all. Calibration does not use the DMP firmware. Calibrating is only attempting to zero or all sensors. This includes the accelerometer detecting gravity. Now for the digital motion...

Let's see if we can get close Note that the firmware is loaded into the MPU and just prior to this Also, note that the firmware in the example has...

Per Application Note Programming Sequence for DMP Hardware Functions:

Also, I messed around with some quaternion math. ``` void calculateYPR(float *data, Quaternion *q){ float qw = (q -> w); float qx = (q -> x); float qy = (q...

@Captain-ZR Are you talking about the calibration routine or the orientation matrix?

@Hortay Use the 6.12 version it has everything the older 4.1 version has with all the bug fixes. If there are functions missing let us know they should transfer form...

@Hortay I'll do my best. What questions do you have? Z
