|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines into
|
|
your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device uled"
|
|
.Cd "device usb"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time,
|
|
place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
uled_load="YES"

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Dream Cheeky WebMail Notifier device.
|
|
.Pp
|
|

|
|
.Pa /dev/uled0
|
|
device can be used by userland applications.
|
|
.Sh IOCTLS
|
|
The following
|
|
.Xr ioctl 2
|
|
commands can be performed on
|
|
.Pa /dev/uled0 ,
|
|
which are defined in
|
|
.In dev/usb/uled_ioctl.h :
|
|
.Bl -tag -width indent
|
|
.It Dv ULED_GET_COLOR
|
|
The command returns LED colors with values for RGB.
|
|
This
|
|
.Xr ioctl 2
|

takes the following structure:
|
|
.Bd -literal
|
|
struct uled_color {
|
|
uint8_t red;
|
|
uint8_t green;
|
|
uint8_t blue;
|
|
};
|
|
.Ed
|
|
.It Dv ULED_SET_COLOR
