.SS "Backlight"
.IX Subsection "Backlight"
If you have a switchable backlight. \fIOptional. Type uniline. default: 'no'.\fR
.SS "Brightness"
.IX Subsection "Brightness"
Set brightness of the backlight (lcd2usb and usb4all):
Brightness is the brightness while the backlight is set to 'on'. \fIOptional. Type integer. upstream_default: '800'.\fR
.SS "CharMap"

.SS "ConnectionType"
.IX Subsection "ConnectionType"
Select what type of connection. See documentation for available types. \fIOptional. Type uniline. default: '4bit'.\fR
.SS "Contrast"
.IX Subsection "Contrast"
Set the initial contrast (bwctusb, lcd2usb, and usb4all) \fIOptional. Type integer. upstream_default: '800'.\fR
.SS "DelayBus"
.IX Subsection "DelayBus"
You can reduce the inserted delays by setting this to false.
On fast PCs it is possible your \s-1LCD\s0 does not respond correctly.
Default: true. \fIOptional. Type uniline. default: 'true'.\fR
.SS "DelayMult"
.IX Subsection "DelayMult"
If your display is slow and cannot keep up with the flow of data from
LCDd, garbage can appear on the LCDd. Set this delay factor to 2 or 4
to increase the delays. Default: 1. \fIOptional. Type uniline. upstream_default: '2'.\fR
.SS "Device"
.IX Subsection "Device"
Device of the serial, I2C, or \s-1SPI\s0 interface \fIOptional. Type uniline. upstream_default: '/dev/lcd'.\fR
.SS "ExtendedMode"
.IX Subsection "ExtendedMode"
If you have an \s-1HD66712,\s0 a \s-1KS0073\s0 or another controller with 'extended mode',
set this flag to get into 4\-line mode. On displays with just two lines, do
not set this flag.
As an additional restriction, controllers with and without extended mode
\&\s-1AND 4\s0 lines cannot be mixed for those connection types that support more
than one display! \fIOptional. Type uniline. upstream_default: 'yes'.\fR
.SS "KeepAliveDisplay"
.IX Subsection "KeepAliveDisplay"
Some displays (e.g. vdr-wakeup) need a message from the driver to that it
is still alive. When set to a value bigger then null the character in the
upper left corner is updated every <KeepAliveDisplay> seconds. Default: 0. \fIOptional. Type uniline. upstream_default: '0'.\fR
.SS "KeyMatrix_4_1"
.IX Subsection "KeyMatrix_4_1"
If you have a keypad you can assign keystrings to the keys.
See documentation for used terms and how to wire it.
For example to give directly connected key 4 the string \*(L"Enter\*(R", use:
  KeyDirect_4=Enter
For matrix keys use the X and Y coordinates of the key:
  KeyMatrix_1_3=Enter. \fIOptional. Type uniline. default: 'Enter'.\fR
.SS "KeyMatrix_4_2"
.IX Subsection "KeyMatrix_4_2"
\&\fIOptional. Type uniline. default: 'Up'.\fR
.SS "KeyMatrix_4_3"
.IX Subsection "KeyMatrix_4_3"
\&\fIOptional. Type uniline. default: 'Down'.\fR
.SS "KeyMatrix_4_4"
.IX Subsection "KeyMatrix_4_4"
\&\fIOptional. Type uniline. default: 'Escape'.\fR
.SS "Keypad"
.IX Subsection "Keypad"
If you have a keypad connected.
You may also need to configure the keypad layout further on in this file. \fIOptional. Type uniline. default: 'no'.\fR
.SS "Lastline"
.IX Subsection "Lastline"
Specifies if the last line is pixel addressable (yes) or it controls an
underline effect (no). \fIOptional. Type boolean. upstream_default: 'yes'.\fR
.SS "LineAddress"
.IX Subsection "LineAddress"
In extended mode, on some controllers like the \s-1ST7036 \s0(in 3 line mode)
the next line in \s-1DDRAM\s0 won't start 0x20 higher. \fIOptional. Type uniline. upstream_default: '0x20'.\fR
.SS "OffBrightness"
.IX Subsection "OffBrightness"
OffBrightness is the brightness while the backlight is set to 'off'. \fIOptional. Type integer. upstream_default: '300'.\fR
.SS "OutputPort"
.IX Subsection "OutputPort"
If you have the additional output port (\*(L"bargraph\*(R") and you want to
be able to control it with the lcdproc \s-1OUTPUT\s0 command. \fIOptional. Type uniline. default: 'no'.\fR
.SS "Port"
.IX Subsection "Port"
I/O address of the \s-1LPT\s0 port. Usual values are: 0x278, 0x378 and 0x3BC.
For I2C connections this sets the slave address (usually 0x20). \fIOptional. Type uniline. default: '0x378'.\fR
.SS "RefreshDisplay"
.IX Subsection "RefreshDisplay"
If you experience occasional garbage on your display you can use this
option as workaround. If set to a value bigger than null it forces a
full screen refresh <RefreshDiplay> seconds. Default: 0. \fIOptional. Type uniline. upstream_default: '5'.\fR
.SS "Size"
.IX Subsection "Size"
Specifies the size of the \s-1LCD.\s0
In case of multiple combined displays, this should be the total size. \fIOptional. Type uniline. default: '20x4'.\fR
.SS "Speed"
.IX Subsection "Speed"
Bitrate of the serial port (0 for interface default) \fIOptional. Type uniline. default: '0'.\fR
.SS "vspan"
.IX Subsection "vspan"
For multiple combined displays: how many lines does each display have.
Vspan=2,2 means both displays have 2 lines. \fIOptional. Type uniline. upstream_default: '2,2'.\fR
