BMI088 FIFO synchronization with external interrupts

[michap]

Hi,

I have an external pulse on INT4 (Gyro) of a BMI088.

I would like to "see" this pulse in the gyro data as descibred in the FIFO usage application note.

Is there any example code that implements the description in the note already?

I don't find any in the Sensor API repository: https://github.com/boschsensortec/BMI08x_SensorAPI 

Best, Michael

Hi,

Thanks for your inquiry.

BMI088 FIFO can log external interrupt signal on INT1 pin or INT2 pin only, not INT3 pin or INT4 pin as shown below.

So if you connect your external pulse to BMI088 INT1 pin or INT2 pin, you should be able to see the pulse in FIFO data.

Thanks.

Hi,

appreciate your response.

I was reading the "BMI08x FIFO usage" application note by BOSCH, BST-MIS-AN005-01

On page 11, I read about the gyro and INT3 and INT4. Did BOSCH invalidate this later?

Please see here.

Thanks

Hi,

Sorry about that. It is true that gyro FIFO can also show tag from INT3 pin or INT 4 pin. Let me check if we have such sample code available or not and then get back to you.

Thanks.
