<title>The sed1330 Driver</title>
<para>
This section talks about using LCDproc with LCD displays that use the
sed1330 chipset.
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.

Connections below are for the G242C, G121C and G321D displays.
Always consult documentation about the specific display before asuming
the connections given here are also correct for your display !

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.
