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.

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.

Contrary to other drivers the character size of an LCD is not given 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.
