The sed1330 Driver
This section talks about using LCDproc with graphical LCD displays driven by the EPSON/SMOS SED1330 or SED1335 LCD controllers, which may also be known by their new names: S1D13300 (= SED1330) and S1D13305 (= SED1335).
The displays are driven in text mode using their built-in character generator and the graphic mode for bars and the heartbeat icon (a bouncing ball).

Connections
Displays using SED1330/1335 chipset come in a variety of pin-outs and power configurations. They usually require negative voltage for contrast and some displays have a negative voltage generator onboard.
Connections below are for the G242C, G121C and G321D displays. Always consult documentation about the specific display before assuming the connections given here are also correct for your display!

The potentiometer should be connected like this on these display modules:


	=== GND

	| |5k

	 |
	 |
	.-.10k potentiometer

	 O Vlc (= -24V)

The G242C generates -24V internally. It is available on Vlc.
To generate -24 from the +5V without an external power source, you can use the following circuit.

The sed1330 driver supports the same direct keys and matrix keypad connections as the hd44780 driver. See .

Configuration in LCDd.conf

[sed1330]
CellSize = 	 Specify the size of a character in pixels. WIDTH may vary between 6 and 8; legal values for HEIGHT range from 7 to 16. If not given CellSize defaults to 6x10.
Contrary to other drivers the character size of an LCD using the sed1330 driver is not given directly. Instead it is determined by the pixel size of the display, which is derived from the display type setting and the character cell size specified with this setting.
ConnectionType = { classic | bitshaker } 	 Select the type of the wiring, see Connections.
If not given, it defaults to classic.
Port = PORT 	 Specify the address of the parallel port the LCD is connected to. Common values for PORT are 0x278, 0x378 and 0x3BC. If not given, it defaults to 0x278.
Type = { G321D | G121C | G242C | G191D | G2446 | SP14Q002 | HG25504 } 	 Type of LCD module. Besides other things (internal setup) this configuration setting determines the size of the display in pixels.
Type	Size (in pixels)
G321D	320 x 200
G121C	128 x 128
G242C	240 x 128
G191D	192 x 192
G2446	240 x 64
SP14Q002	320 x 240
HG25504	320 x 240
Currently the G321D and SP14Q002 are the only ones that this driver is tested with.
