it all depends on how you have the IMU orientated. And adjusting the code accordingly.
There are plenty of comments in the code… an example is below.
####################################################################
######################Correct rotation value########################
####################################################################
#Change the rotation value of the accelerometer to -/+ 180 and
#move the Y axis '0' point to up.
#
#Two different pieces of code are used depending on how your IMU is mounted.
#If IMU is up the correct way, Skull logo is facing down, Use these lines
AccXangle -= 180.0
if AccYangle > 90:
AccYangle -= 270.0
else:
AccYangle += 90.0
#
#
#
#
#If IMU is upside down E.g Skull logo is facing up;
#if AccXangle >180:
# AccXangle -= 360.0
#AccYangle-=90
#if (AccYangle >180):
# AccYangle -= 360.0
