The first chip supported was T6963C. There are also driver for other LCD's such as SED and KS0108. The most popular LCD's will be supported with a custom driver.

 

The following connections were used for the T6963C:

 

PORTA.0 to PORTA.7 to DB0-DB7 of the LCD

PORTC.5 to FS, font select of LCD

PORTC.2 to CE, chip enable of LCD

PORTC.3 to CD, code/data select of LCD

PORTC.0 to WR of LCD, write

PORTC.1 to RD of LCD, read

PORTC.4 to RESET of LCD, reset LCD

 

 

 

The LCD used from www.conrad.de needs a negative voltage for the contrast.

 

Two 9V batteries were used with a pot meter.

Some displays have a Vout that can be used for the contrast(Vo)

 

The T6963C displays have both a graphical area and a text area. They can be used together. The routines use the XOR mode to display both text and graphics layered over each other.

 

 

The statements that can be used with the graphical LCD are :

 

[[CLS]], will clear the graphic display and the text display

CLS GRAPH will clear only the graphic part of the display

CLS TEXT will only clear the text part of the display

 

[[LOCATE]] row,column : Will place the cursor at the specified row and column

The row may vary from 1 to 16 and the column from 1 to 40. This depends on the size and mode of the display.

 

[[CURSOR]] ON/OFF BLINK/NOBLINK can be used the same way as for text displays.

 

[[LCD]] : can be handled the same way as for text displays.

 

[[SHOWPIC]] X, Y , Label  : Show image where X and Y are the column and row and Label is the label where the picture info is placed.

 

[[PSET]] X, Y , color :  Will set or reset a pixel. X can range from 0-239 and Y from 9-63. When color is 0 the pixel will turned off. When it is 1 the pixel will be set on.

 

[[$BGF]] "file.bgf"  : inserts a BGF file at the current location

 

[[LINE]](x0,y0) – (x1,y1) , color : Will draw a line from the coordinate x0,y0 to x1,y1.

Color must be 0 to clear the line and 255 for a black line.

 

[[BOX]](x0,y0)-(x1,y1), color  : Will draw a box from x0,y0 to x1,y1. Color must be 0 to clear the box and 255 for a black line.

 

[[BOXFILL]](x0,y0)-(x1,y1), color  : Will draw a filled box from x0,y0 to x1,y1. Color must be 0 or 255.

 

The Graphic routines are located in the glib.lib or glib.lbx files.

You can hard wire the FS and RESET and change the code from the glib.lib file so these pins can be used for other tasks.

 

= COLOR LCD =

Color displays were always relatively expensive. The mobile phone market changed that. And Display3000.com , sorted out how to connect these small nice colorful displays.

You can buy brand new Color displays from Display3000. MCS Electronics offers the same displays.

There are two different chip sets used. One chipset is from EPSON and the other from Philips. For this reason there are two different libraries. When you select the wrong one it will not work, but you will not damage anything.

LCD-EPSON.LBX need to be used with the EPSON chipset.

LCD-PCF8833.LBX need to be used with the Philihps chipset.

As the color display does not have a built in font, you need to generate the fonts yourself.

You can use the [[Font Editor|Fonteditor]] for this task.

 

A number of statements accept a color parameter. See the samples below in bold.
