Hello
How do I convert the Rawdata of the Gyroscope and the accelerometer into °/s and m/s^2?
Do I need to multiply the raw data with the typ. value of the sensitivity? (LSB/°/s)
How do I know which range I am having in my programme, when I did not set any?
Kind regards
Sophie
Hi Sophie，
How do I convert the Rawdata of the Gyroscope and the accelerometer into °/s and m/s^2?
-----> For Acc if the register data is 16-bits
Sensitivity(in datasheet) = (2^15)/Range .
Example: Range = +/-8G, then sensitivity = (2^15)/8 * 9.8 (LSB/m/s^2)
m/s^2 = Raw_data / sensitivity
For Gyo , if the register data is 16-bits
Sensitivity(in datasheet) = (2^15)/Range
Example: Range = +/-2000dps, then sensitivity = (2^15)/2000 (LSB/°/s)
°/s = Raw_data / sensitivity
Do I need to multiply the raw data with the typ. value of the sensitivity? (LSB/°/s)
-------> No. Raw data (LSB) divided by the corresponding sensitivity
How do I know which range I am having in my programme, when I did not set any?
-------> please check the sensor's datasheet register map,
Address 0x41 for Acc range setting; 0x43 for Gyro range setting
