I try to put your IMU code into my project, the acceleration sensor is
mma7260,the gyroscope is enc03。using the cortex-m3 series mcu sampling the
voltage and calculate the three-axis acceleration and angular velocity.And then
calls the function MadgwickAHRSupdateIMU(gx,gy,gz,ax,ay,az),Set the sample
frequency 200.f and betaDef 0.1f,then computed the euler angles directly from
quaternion data using the equations (7) (8) (9) mentioned in your excellent
report.But the result is very extremly unstable,there are great error even
though the platform is stationary,that is bad than simple integral.
could you reply my questions and help me solving the problem。
very thankful
