BHI160B Soft Pass-through

[SimonLi]

I am accessing the internal BMI160 about BHI160B, and I found a method called "Soft Pass-through" in datasheet.

Because I want to get more than 200Hz sampling rate, but the maximum value of BSX ODR is 200Hz, and the BMI160 sampling rate can reach 1600Hz.

But I don't know how to use "Soft Pass-through". Can teach me how to use it.

Or another way to obtain BMI160 sensor data without going through BSX sensor fusion.

Hi SimonLi,

"Soft Pass-through" is available in BHI160 fw and sensor API. Calling the bhy_soft_passthru_write() and bhy_soft_passthru_read() interfaces can write or read the registers of BMI160, for example:
bhy_soft_passthru_write(0x68,regaddr,pBuffer,length,0);
bhy_soft_passthru_read(0x68,regaddr,pBuffer,length,0);

You can read the RAW data of BMI160 by calling the bhy_soft_passthru_read() read interface.

Hi BSTRobin,

Thanks for your reply. It is useful.
