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 !
Ok, so it is very interesting. You are correct, where is ANYMOTION interrupt, while it says it has on feuture page, goining into registers on datasheet gives no results.
While goingoin frough API, now i can find it. Why can they put this information on datasheet ?
