Hello, I have not seen the zero offset of the gyroscope and accelerometer, high-frequency random noise, and related time of sensor error in the data manual and user manual of IMU383 provided on the official website.Could you please provide me with these parameters of IMU383, which are extremely important for us to build the error model. Thank you for your reply.

@cek I only use the burst mode to read, but the data is incorrect. My imu383 is on the table and does not move, but the data display is not close to zero. But when I only read in polling mode, the data is correct. Did I overlook something?

@cek The current situation is like this, the xyz-rate and xyz-acc of imu383 cannot be read all at once.
The same reading code, I can only get 04, 08, 0C or 06, 0A, 0E,May I ask where is the problem?

@cek But 0x04-19 in the manual are reserved，Does this mean I can't read the corresponding value by reading register 0x04-0E？
And the same program reads 0x04-0E of imu381 is correct, but it does not work on imu383, why is this?

@cek said in IMU383 SERIES USER MANUAL:

we found and confirmed they are need to be updated, we will update it later.
pls use user manual in Aceinna link:

I found in the link you provided that the product ID is still inconsistent.Can you tell me which one is correct?
And, can you tell me which register xyz_rate and xyz_acc can be read in polling mode?

1.On page 13 it is stated that the product ID is 0x3813, and on page 19 it is stated that the product ID is 0x3830, which one is correct?
2.The register addresses of xyz_rate and xyz_acc are not stated in the manual. Where should I read their values?
