Hello there:
I want to enable anymotion feature on BMI270 but not map to any physical interrupt pins. MCU checks the status by reading INT_STATUS0 every 1 second through SPI. I am expecting bit 6 of INT_STATUS set flag as I move the sensor, but the output is alwasy 0. Below is how I do it.
Procedure:
- Initialize BMI270 as performance opt mode with ODR as 25/8, and Power save mode;
- Enable INT_LATCH by setting it to 1;
- Set FEAT_PAGE to 1;
- Set ANYMOTION1 and ANYMOTION2 as 0xE005, 0Xb8AA (output to bit6, 5 samples, x, y, z enabled, 83mg )
- Write whole page values to FEATURES[0-15]
- Disable acc, gyro and temperature until main function.
- In the main function enable acc, gyro and temperature and read INT_STATUS0
I am pasting the code screeshot of each steps
Step 1: Initialization
Step 6 see the last line of code in the step 1 picture.
Step 7 read and display INT_STATUS
Couple note:
- BMI270 is configured correct and config file is uploaded correctly. Acc and gyro is operation correctly. I can get the data out;
- During initialization, I read the Feature 0 -15 and then write the value to them then read values again. However, the read after register writing dosent give correct values, shown as below 1, 2, 3 and red highlight.
Appriciate your help. Thanks in advance.

Hi, I am facing a similar issue with BMI270.
I am able to configure sensors and get acc and gyro data. after that, I configure the 0x2F with the value of 1. And then read to see the default value at 0x3C and 0x3E. and I get the value 0x0000. on checking all the addresses from 0x30-0x3F all show 0x00.
