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 !

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 |
Currently the G321D and SP14Q002 are the only ones that this driver is tested with.
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.
