BMI160 Accelerometer

Hello All,

I see the following messages when BMI160 is being accessed. It is set to use the FIFO and interrupts on FIFO FULL [still in testing].

Any thoughts? Let me know if any details needed.

I2C issue: it is now powered up. It’s not actually BMI160. It’s an IoT Card. Resolved now.

Thanks

Always good to read the messages, and do what they tell you!

:wink:

Now please mark the thread as solved.
