Colour lcd serial 132X132 graphic display VT100
Based on the Nokia Phone display this can be connected to a Microcontroller or PC COM port, via an adapter, to give full colour text and graphics The resolution is 132 x 132 pixels.
Display actual display area is 26mm x 26mm and it is mounted on a PCB that is 36mm x 50mm. The depth including the connectors is approximately 15mm.
The display used is a new Nokia replacement and so the type and quality varies considerably from batch to batch. It is possible to use your own display but the populated circuit boards are not sold separately. The display is attached to the board by non-setting adhesive (sticky dots).
When used for text the display has two fonts, a bold and a normal font. The normal font will give 21 characters across the screen and 16 lines down. This display is ideal for displaying system information on a PC or for making that Microcontroller project something special. C Source code is available for displaying text files from a PC to this display. The full datasheet and code can be found at www.asi.byvac.com
NOTE: Older version illustrated, the new version has two rows of pins at the top.
The display uses a subset of the original VT100 escape commands and also many others in addition to enable drawing graphic objects. The VT100 command set is still used in terminal programs and in its time was so popular that it became a standard.
When the display is connected to say HyperTerminal anything that is typed in will appear on the display. To get the display to respond to commands, to change to the bold font for instance, escape codes are used. The bold font would be esc(2. This is the escape key followed by a round bracket followed by '2' from now on anything typed will be bold. To change the text colour to blue this would be esc[3f, now everything typed is in blue text. So on and so forth.
Other escape codes are used for drawing the graphics and they are all listed and explained in the datasheet. As an example on the above picture, the 'C O L O U R', using different coloured letters is this piece of text:
*[224fC *[28fO *[3fL *[252fO *[227fU *[31fR
The escape character is shown as a '*' because this cannot be printed to this text document. An escape code is used to change the colour of the foreground before each letter. This is simply text that can be a text file and sent with HyperTerminal or any other program that can send text files. At the above web site there is a program called scom (full C source is also provided) that will send a text file to the PC COM port. There are many other commands for example for drawing squares and circles.
When connecting to a microcontroller there is no need for a translation device and it is also possible to connect multiple displays by making use of the Display Disable feature.
The Microcontroller uses a GPIO line to disable two displays whilst keeping one active.
