BMI270 Data Synchronism through via external synchronization signals

[ximu]

I have already implemented the data reading of bmi270 and asked bmi270 to send data ready to interrupt STM32, but I want to use 32 bmi270 to make a sensor array, hoping to send a synchronization signal to bmi270 through stm32, so that multiple BMI270s can sample and send data simultaneously.

I have two questions.

1、Whether the bmi270 has the function of triggering sampling through external synchronization signals？

2、If so, how to configure it. If not, can multiple BMI270s be sampled at the same time by other means?

Hi ximu,

Thank for your inquiry.
BMI270 supports external hardware signal synchronization of FIFO data. You can refer to the description in BMI270 data sheet.

In addition, for your application, you can also set all BMI270 to the maximum ODR, and sensor data can be updated quickly without synchronizing sensor data. The host can directly read them.
