    Low power IMU with miotion triggered interrupt and very good gyro and crach detection questions

    Low power IMU with miotion triggered interrupt and very good gyro and crach detection questions

    Hello,
    I am working on project where I need to detect motion with as low power as possible to wake-up MCU from deepsleep, but at the same time I would like to have gyro that can be used for ultraprecise orientation calculation (lean angle of motorcycle)

    Any time I stumble on good IMU all INT lines are mapped to data redy/fifo overflow, and so one, none of them are connected to motion trigger.

    As example i would love to use BMI085, but all  INT lines are not usable for my needs. What i don't whant to do is keep reading IMU to see orientation, it is not a problem, but i would like to have as much deep sleep from MCU as possible.

    Only IMU with INT mapped to motion trigger was BMI160, but gyro is 3x (?) worse to BMI085.


    Any recomendation ?  Or maybe I am missing something ?

    Thank you !

    We have readme in Github along with the API which you can find in same link you got. 

    Except that, we don't have other datasheet for API.
