(LSM6DSL) I want to know why raw data(angular rate) is multiplied by sensitivity.

Multiply the angular velocity(gyro raw data) by sensitivity and it becomes mdps, what exactly is mdps?

float_t lsm6dsl_from_fs500dps_to_mdps(int16_t lsb)

{

  return ((float_t)lsb * 17.50f);

}

Hi @jjo.2​ ,

"mdps" means milli degree per second, which is the measurement of an angular rate.

You need to multiply the LSB data by a specific factor because it refers to the sensitivity according to the datasheet of the mechanical element inside the sensor.

Thank you for your answer. One more question is, do you have a formula or example code to calculate the angle using raw data?

I also want to know if there is an example code using a complementary filter.
