Adjustment for LPVR-DUO

By default low pass filtering is applied to LPMS-IG1 gyroscope output. This improves the quality of the signal for applications with slow rotations. In case of faster rotations e.g. in a motion simulator it is recommended to change the low-pass filter settings for the sensor to become more responsive. Please follow the steps below to do this:

...

1. Accelerometer settings:

   • AR (accelerometer range, g): 2, 4 (default), 8, 16

   • AOR (accelerometer data output rate, Hz): 3, 7, 15, 31, 62, 100 (default), 125, 200, 250, 500, 1000

   • AF (accelerometer 3-dB bandwidth, Hz): 5, 10 (default), 21, 45, 99, 218, 420

2. Gyroscope settings:

   • GR (gyro range, dps): 400 (default), 1000, 2000

3. Gyroscope I (high precision) settings:

   • G1OR (gyro data output rate, Hz): 100, 200, 400, 800, 1600, 3200, 6400, 12800 (default)

   • G1F (gyro low pass filter): value of G1F is calculated as LpfOrder*1000 + LpfFrequency

     • LpfOrder (low pass filter order): 2, 3, 4 (default)

     • LpfFrequency (low pass filter cutoff frequency, Hz): 10 (default), 35, 45, 50, 70, 85, 100, 140, 175, 200, 285, 345, 400, 500

     • Default value: 4*1000 + 10 = 4010

4. Gyrosocpe Gyroscope II (High range) settings:

   • G2OR (gyro data output rate, Hz): 3, 7, 15, 31, 62, 100 (default), 125, 200, 250, 500, 1000

   • G2F (gyro 3-db bandwidth, Hz): 5, 10 (default), 20, 41, 92, 176

IMPORTANT: Please make sure AOR and G2OR settings are the same. This is because the accelerometer and gyroscope II belongs to the same chip and share the same data output rate. In case of different values, G2OR value will be used to set the chip data output rate.
