Description
Adds keybindings for screen rotation and auto rotation from an accelerometer.
Setup
Find an accelerometer device in sysfs (cat /sys/bus/iio/devices/iio*/name,
or using a script: monitor-iio.sh)
Find the raw output file of the accelerometer
(e.g. cat /sys/bus/iio/devices/iio:device0/in_accel_x_raw should output an integer).
Add the raw output file names to the dwl configuration accel_*.
Add a udev rule to uniquely identify the device, for example:
sudo echo 'SUBSYSTEM=="iio", KERNEL=="iio*", ATTR{name}=="accel_3d", GROUP="input", SYMLINK+="input/accel"' >> /etc/udev/rules.d/99-accel.rules
sudo udevadm control --reload-rules && sudo udevadm trigger
(the device is probably already in /dev/ e.g. /dev/iio:device0 but on my computer the number changes after a reboot)
A symlink to the device should now be available in /dev/input/ and accessible to input group members.
Add the device path to the dwl configuration accel_path.
Config
rotation_enabled: If the auto rotation is enabled on startup.rotation_delay: How often to check the accelerometer values in milliseconds.rotation_flat: Threshold on the normalized Z axis to consider the device flat and stop the auto rotation.rotation_thresh: Rotation threshold after which the screen flips (values less than 0.5 will cause a back and forth).
accel_path: The path to the accelerometer device file (e.g. "/dev/input/accel").accel_x: The name of the sysfs file for the accelerometer x axis.accel_y: The name of the sysfs file for the accelerometer y axis.accel_z: The name of the sysfs file for the accelerometer z axis.
Default keybindings:
<Modkey>+<Shift>+<Arrows>: Change the screen rotation manually (doesn't disable the auto rotation).<Modkey>+<Shift>+<R>: Enable/disable the auto rotation.
