    BMI270 gyro

    In Bosch Sensortec | BMI270 Data sheet:

    page 110 - Register (0x42) GYR_CONF  says that odr_6k4 is reserved.

    page 2 says: Output data rates (ODR): 25 Hz ... 6.4 kHz (gyroscope) and 0.78 Hz ... 1.6 kHz (accelerometer)

    How can I set odr_6k4 for gyro ?

    If gyro ODR is 3k2 I'm getting about 60 interrupts per sec (with my watermark settings). If I chane ODR to 6k4 I'm getting about 24 interrupts per sec.

    Hi,

    Thanks for your inquiry.

    If you set register 0x45 bit-3 gyr_fifo_filt_data to 0, then gyro unfiltered data will be filled in FIFO at 6.4KHz rate.

    Thanks.

    I set register 0x45 bit-3 gyr_fifo_filt_data to 0 but gyro data ready interrupt is still 200Hz and not 6.4KHz rate.

    Do I need to set other register?

    Hello kpoon12, 

     

    Technically, you need to clear 4th bit in 0x45 register. 

    But, this is not that all for your fifo setting. 

    Therefore, I don't recommend to develop BMI270 w/o API. (If now, you are using our BMI270 API, that's great!) 

    Please BMI270 API as below URL. 

    https://github.com/BoschSensortec/BMI270-Sensor-API

    And here is the my gyro fifo 6.4k ODR example code as attaced file. 

    Thanks,
