Formula for calculating angle:
Roll angle(x axis) Roll=((RollH<<8)|RollL)/32768*180(°)
The pitching angle(y axis) Pitch=((PitchH<<8)|PitchL)/32768*180(°)
Yaw angle(zaxis) Yaw=((YawH<<8)|YawL)/32768*180(°)
Formula for calculating temperature
T=((TH<<8)|TL) /340+36.53
Checksum
Sum=0x55+0x53+RollH+RollL+PitchH+PitchL+YawH+YawL+TH+TL
Attention
The coordinate system used for attitude angle settlement is the northeast
sky coordinate system. Place the module in the positive direction, as shown
in the figure on Chapter 3.3, direction right is the X-axis, the direction
forward is the Y-axis, and direction upward is the Z-axis. Euler angle
represents the rotation order of the coordinate system when the attitude is
defined as Z-Y-X, that is, first turn around the Z-axis, then turn around the
Y-axis, and then turn around the X-axis.
