The Toshiba T6963 Driver
This section talks about using LCDproc with LCD displays that use the
T6963 chipset from Toshiba. Usually, this chipset is used on big character LCD
displays that can often act as a screen.
The driver uses the text mode of the chipset with a custom font loaded which
resembles the characters from Code Page 437.
Only displays in 'Single Scan' configurations are supported. Displays configured
as 'Dual Scan' are currently not supported. Those use onboard memory differently.
Check the datasheet of your display!
Connections
Displays using T6963 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. Therefore the wiring table below does
only list signal names, not LCD pins. Be sure to get the correct datasheet
for your display and identify the pins to use!
We do not give wiring examples for power, contrast, and other control lines.
You have to figure out this from your display's datasheet!

Compiling
Make sure that the T6963 files are built when you run configure. This
can be done by specifying "--enable-drivers=all" or by
"--enable-drivers=t6963".
Configuration in LCDd.conf
[t6963]
Size = ¶meters.size;
set display size [default: 20x6]
Port =
PORT
Specify the address of the parallel port the LCD is connected to.
Common values for PORT are 0x278,
0x378 and 0x3BC.
Legal values are 0x200 - 0x400.
If not given the default value is 0x378.
ECPlpt = ¶meters.yesdefno;
Is ECP mode on? [default: yes; legal: yes, no]
Despite its name, this driver does not use ECP mode of parallel port. This
option turns bi-directional mode of the port on or off. Leave this on
unless you experience problems.
graphic = ¶meters.yesnodef;
Use graphic? [default: no; legal: yes, no]
Enables / disables drawing of the content of the graphic RAM. This is
currently a no-op as the driver does not make use of the graphic RAM.
