### 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](https://github.com/Unprex/dotfiles/blob/main/scripts/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: * `` + `` + ``: Change the screen rotation manually (doesn't disable the auto rotation). * `` + `` + ``: Enable/disable the auto rotation. ### Download - [2022-10-25](https://github.com/djpohly/dwl/compare/main...Unprex:rotation.patch) ### Authors - [Unprex](https://github.com/Unprex)
