    Limited Range on BMI323

    Limited Range on BMI323

    Hi, 

    I'm using a BMI323 Shuttle Board 3.0 Flyer connected in I²C on an Arduino Uno R3 thanks to a level shifter.

    My problem is when I read X, Y or Z axis, the return value sould be between 0 and 65535 (2^16). But my usable range is 49152 -> 16384, the other part (from 16385 to 49151) is never returned, why ?

    My accelerometer is setup as follow: 

    * ODR: 0x000B -> 800Hz
    * range: 0x0000 -> 2G
    * filtering: 0x0000 -> ODR/2
    * average: 0x0600 -> 64 sample
    * mode: 0x7000 -> High

    So I send 0x760B to the ACC_CONF register. 

     

    Thanks ! 🙏

    Hi dev_gnrb,

    If you set BMI323 acc range to 2G, raw data output range should be -16384~+16384.
