bmi270 CAN NOT SET ACCELARATION BANDWIDTH res_avg16 on arduino teensy 4.1 board

[jimit007]

hi,

jimit here, I recently buy a bmi270 IMU, for my flight controller project, I successfully initialize the sensor without any problem(writing a config file with help of a datasheet) now I initialize the sensor in normal mode and start pulling the acceleration sensor data, I set  ACC_range = 2G,  then I set the ODR 200Hz, bandwidth on res_avg16 mode, then I show now I see I get Acceleration on the Z axis 4175 - 4185 instead of  16384, I don't know why this happened then I check 0x1b Event resistor, I see I get Error of 1, means ACC_CONFIG error, I am pretty sure I write right resistor on my config file I can show you in my code,  please check my code and guide me what did I wrong, thank you!

Hi, 

Why don't you use our API? 

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

Here is the Arduino example code based on API. 

It's not latest API, so please update the bmi270 and bmi2 with above URL. 

Thank you.

brother, I am building a flight controller, I don't want to use any API implementation code please can you help me? am I right or wrong in my code? can you please check my code? I request you!

Hi Jimit, 

If you need my help for register programming, please provide your data log using logic analyzer. 

Then, I can check where is problem. 

Thanks,
