How to use Motion detection interrupt of MPU9250
Posted: Sat May 30, 2020 1:29 am
Hey,
I'd like to use the internal MPU9250 with it's internal motion detection interrupt to wake up the Freematics ONE+ Model B. The Interrupt Pin is Pin 12 on the MPU9250. But is it connected to the ESP32? Where does it arrive?
In the scheme https://freematics.com/dl/schematics_on ... 190612.pdf the pin signal going away from the MPU9250 is called MPU_INT, but I cannot find it arrive anywhere.
Have I missed something?
Or is there any other easy way of using the Freematics ONE+ Model B as a motion detecting theft alarm device in lowest power sleep mode?
