This section talks about using LCDproc with LCD displays that use the T6963 chipset from Toshiba. Usually, this chipset is used on big graphical 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. If your display has a 'Font Select' pin it must be wired to use the 6x8 font. Only displays in 'Single Scan' configurations are supported. Displays configured as 'Dual Scan' are currently not supported. Those use on-board memory differently. Check the datasheet of your display! 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 on-board. 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! Parallel port <-> LCD name pin name pin nSTRB 1 /WR * D0-D7 2-9 DB0-DB7 * nLF 14 /CE * INIT 16 C/D * nSEL 17 /RD * VDD FS * 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". Size = ¶meters.size; Set display size in characters [default: 20x6]. Do set it as close as possible to the pixel size of the display (based on a 6x8 font). Otherwise characters will repeat on the right of a line. Example: 21x8 on a 128x64 display. 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. bidirectional = ¶meters.yesdefno; Use LPT port in bi-directional mode. [default: yes; legal: yes, no] Most LPT ports can be used in bi-directional mode. It is required for proper timing of the display. Leave this on unless you experience problems. ClearGraphic = ¶meters.yesnodef; Clear graphic memory on start-up [default: no; legal: yes, no]. The T6963 has a graphic and a text area which can be combined using several modes. This driver uses default OR-mode. Usually the graphic area is empty after power-on but if you see random garbage overlaying the text this option may be enabled. delayBus = ¶meters.yesnodef; Use additional delay in read / write operations. [default: no; legal: yes, no]. The display can execute operations very fast. As the driver implements busy checking no additional delays are required. But if you experience problems you may try to slow down communication by enabling this setting.
