How to shut down internal compensation operation of bmi270?

[Rainy]

Hello, everyone!

This is my first time using the BMI 270. I use Max FIFO mode for initialization.

The configuration is as follows：

SPI_WRITE_BYTE(0x7D, 0x0E);
SPI_WRITE_BYTE(0x40, 0xAC);
SPI_WRITE_BYTE(0x42, 0xEE);
SPI_WRITE_BYTE(0x43, 0x08);
SPI_WRITE_BYTE(0x41, 0x02);
SPI_WRITE_BYTE(0x45, 0x00);
SPI_WRITE_BYTE(0x48, 0x00);
SPI_WRITE_BYTE(0x49, 0xC0);
SPI_WRITE_BYTE(0x7C, 0x02);

It takes about one to two hours for the data to stabilize.

I think this has something to do with the temperature rise of the system. We want to do the external temperature compensation operation. How can I turn off the internal compensation operation?

Hi Rainy,

Could we know what is the working environment like as you used BMI270?

Tested at room temperature. The circuit temperature rises from 25 ° C to 40 ° C in one hour.

Hi Rainy,

The current internal compensation is enabled by default. There is no interface to disable it.
