<title>The sed1330 Driver</title>

<para>
|

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).
|
|
</para>
|
|
|
|
<para>
|
|
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).

<para>
|
|
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!
