BMI270 INT line pull up resistor

[cpparm]

Hi,

I use the INT signal on BMI270 to signal to the SoC. I was wondering how I should choose the the pull up resistor value to minimize current consumption and ensure correct operation. The SoC on my board is nRF52840. 

Thanks,

Wei

Hi cpparm, 

You can change push_pull or open drain changing Register 0x53, 0x54. 

Please check page 109, 110.

Please use our API. There is bmi2_set_int_pin_config to function to set INT pin configuration.
