Phone Attitude(Device orientation) - lurkadillian - 06-20-2023
I am having trouble finding any sources online about how to obtain the device orientation. If anybody has any knowledge about any libraries or maybe some global value that tracks this.
I am trying to modify this compass app https://gitlab.com/lgtrombetta/compass/ to allow compass to function when in any orientation(not just with your phone flat).

The accelerometer readings are under /sys/bus/iio/devices/iio:device*/ where * stands for an integer depending on the kernel being used. The correct device is the one having an in_accel_x_raw file (and several other similar files, all giving you accelerometer readings if you cat them).

I was hoping there might be some kind of global value that has been through a filter combining the gyro and accelerometer. Maybe the one the OS uses for screen rotation?
