Hi Ana,

these are automatically generated from IMU_GYRO_SENS. The floating point sens value is approximated by a fraction with *_SENS_NUM as numerator and *_SENS_DEN as denominator. That way this can be done in fixed point with integers instead of doing the multiplication with floating point numbers.
That is why you specify the integer type to use with the SENSE values:
<define name="GYRO_P_SENS" value="1.1032765" integer="16" />

Cheers, Felix

Hi,

I have looked into the imu.h file( in subsystems). I can see a IMU_GYRO_SENS_NUM and IMU_GYRO_SENS_DEN while in the airframe file there is only a IMU_GYRO_SENS. Is it consistent or should there be these parameters defined?

Ana
