DESCRIPTION

       Configuration classes used by Config::Model

       generated from LCDd.conf

Elements

   Backlight
       If you have a switchable backlight.  Optional. Type uniline.

       default value :
           no

   Brightness
       Set brightness of the backlight (lcd2usb and usb4all): Brightness is the brightness while
       the backlight is set to 'on'.  Optional. Type integer.

       upstream_default value :
           800

   CharMap
       Character map to to map ISO-8859-1 to the LCD's character set

       (hd44780_koi8_r, hd44780_cp1251, hd44780_8859_5 and upd16314 are possible if compiled with
       additional charmaps)  Optional. Type enum. choice: 'hd44780_default', 'hd44780_euro',
       'ea_ks0073', 'sed1278f_0b', 'hd44780_koi8_r', 'hd44780_cp1251', 'hd44780_8859_5',
       'upd16314'.

       upstream_default value :
           hd44780_default

   ConnectionType
       Select what type of connection. See documentation for available types.  Optional. Type
       uniline.

       default value :
           4bit

   Contrast
       Set the initial contrast (bwctusb, lcd2usb, and usb4all)  Optional. Type integer.

       upstream_default value :
           800

   DelayBus
       You can reduce the inserted delays by setting this to false.  On fast PCs it is possible
       your LCD does not respond correctly.  Default: true.  Optional. Type uniline.

       default value :
           true

   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.
       Optional. Type uniline.

       upstream_default value :
           2

   Device
       Device of the serial, I2C, or SPI interface  Optional. Type uniline.

       upstream_default value :
           /dev/lcd

   ExtendedMode
       If you have an HD66712, a KS0073 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 AND 4 lines cannot be
       mixed for those connection types that support more than one display!  Optional. Type
       uniline.

       upstream_default value :
           yes

   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.  Optional. Type uniline.

       upstream_default value :
           0

   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
       "Enter", use:
         KeyDirect_4=Enter For matrix keys use the X and Y coordinates of the key:
         KeyMatrix_1_3=Enter.  Optional. Type uniline.

       default value :
           Enter

   KeyMatrix_4_2
        Optional. Type uniline.

       default value :
           Up

   KeyMatrix_4_3
        Optional. Type uniline.

       default value :
           Down

   KeyMatrix_4_4
        Optional. Type uniline.

       default value :
           Escape

   Keypad
       If you have a keypad connected.  You may also need to configure the keypad layout further
       on in this file.  Optional. Type uniline.

       default value :
           no

   Lastline
       Specifies if the last line is pixel addressable (yes) or it controls an underline effect
       (no).  Optional. Type boolean.

       upstream_default value :
           yes

   LineAddress
       In extended mode, on some controllers like the ST7036 (in 3 line mode) the next line in
       DDRAM won't start 0x20 higher.  Optional. Type uniline.

       upstream_default value :
           0x20

   OffBrightness
       OffBrightness is the brightness while the backlight is set to 'off'.  Optional. Type
       integer.

       upstream_default value :
           300

   OutputPort
       If you have the additional output port ("bargraph") and you want to be able to control it
       with the lcdproc OUTPUT command.  Optional. Type uniline.

       default value :
           no

   Port
       I/O address of the LPT port. Usual values are: 0x278, 0x378 and 0x3BC.  For I2C
       connections this sets the slave address (usually 0x20).  Optional. Type uniline.

       default value :
           0x378

   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.  Optional. Type uniline.

       upstream_default value :
           5

   Size
       Specifies the size of the LCD.  In case of multiple combined displays, this should be the
       total size.  Optional. Type uniline.

       default value :
           20x4

   Speed
       Bitrate of the serial port (0 for interface default)  Optional. Type uniline.

       default value :
           0

   vspan
       For multiple combined displays: how many lines does each display have.  Vspan=2,2 means
       both displays have 2 lines.  Optional. Type uniline.
