# This UDEV rule provides the `pwm` user group with access to PWM devices.
# Note that UDEV operates asynchronously, so there may be a slight delay
# between changes to the directory structure (e.g., when a new PWM channel is
# added) and the corresponding permission updates. To ensure the rule has been
# fully applied, you can use the command `udevadm settle` to wait for the UDEV
# process to complete.
