NAME

     uled — USB LED driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines into your kernel
     configuration file:

           device uled
           device usb

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           uled_load="YES"

DESCRIPTION

     The uled driver provides support for Dream Cheeky WebMail Notifier and ThingM blink(1)
     notification LED.

     Subsequently, the /dev/uled0 device can be used by userland applications.

IOCTLS

     The following ioctl(2) commands can be performed on /dev/uled0, which are defined in
     <dev/usb/uled_ioctl.h>:

     ULED_GET_COLOR
             The command returns LED colors with values for RGB.  This ioctl(2) takes the
             following structure:

             struct uled_color {
                     uint8_t red;
                     uint8_t green;
                     uint8_t blue;
             };

     ULED_SET_COLOR
             The command sets LED colors with values for RGB.  It uses the same structure as
             above.
