Simulate KS0108 graphical LCD with Proteus simulator

Today it is very popular to use various circuit and microcontroller simulators when developing programs. Using simulators you have several benefits comparing to real prototype boards like you don’t have to connect any hardware to test a piece of code, you don’t have to be in same place when working – you can have simulator software in Laptop and work where ever you want and of course you can see more parameters within simulator like register values, memory, signals in convenient form.

So controlling graphical LCD on simulator software like Proteus is easy task.

Working with simulator is easier because you don’t have to wary much about additional pins, like MCU power pins, crystals or other protection circuits. You just need to connect control lines and LCD power pins. Thats it. Define microcontroller Clock frequency in Atmega8 symbol and load program file(.hex) by browsing to it in same component meny. And then you can run program. Proteus simulator have KS0108 based 128×64 graphical LCD(LGM12641BS1R) which works as my real GLCD(HQM1286404 ), just in simulator pins are ordered differently than in real one.

Fabian Maximilian Thiele library have also powerful character control functions. First of all Just download GLCDFontCreator2 java program where you can fetch fonts from Windows system and generate fonts for graphical LCD.

Font creator generates convenient file .h with all font data which can be read by program functions.

First of all in the program you have to include font file .h or multiple files.

#include “SC.h”

Then you have to select font which will be used currently:

ks0108SelectFont(SC, ks0108ReadFontData, BLACK);

And then you can simply put tech on the LCD screen with simple command:

ks0108Puts(“scienceprog.com”);

Or if you want from flash memory:

ks0108Puts_P(PSTR(“Test Fonts”));

You can also draw various graphic with functions built in library:

//round rectangle

ks0108DrawRoundRect(5, 5, 117, 20, 8, BLACK);

//line

ks0108DrawLine(5, 50, 122, 50, BLACK);

//circle

ks0108DrawCircle(25, 55, 5, BLACK);

And even more.

  2. It’s a very interesting but i need a code

  3. Link to code is at the end of article

  4. Can you please, suggest us which compiler is used to compile this code?

  5. I Use this example and work very well…. the question is…. can you tell me how to use a fixed width fonts in your example? some think that SystemFont5x7.h. I need this to put formatted text into the glcd. Thanks.

  6. LCD Module @ AORAN-LCD

    More many different alphanumeric types ,graphic types, give you plenty to chose from- 1×8 to 4×40 character displays ,122×32 to320x240 Graphic displays. Standard backlight options of low-power electroluminescent, high-brightness EcoBrightTM non-powered backlight by special order. LED or CFL backlights, low profile edge light options for thinner displays.
    Standard or wide-temperature (-20°C to +70°C) operation. All parts can include an HD44780 compatible controller which can be ordered in either: Standard, European, Cyrillic, Russian, or Greek font options.

    With more than hundreds different combinations in our regular range, we have the display for your application. If we haven’t, we can always fully or semi custom them for you!

  7. thanks you for this fully project
    can you tell me .which compiler you used to compile this code?
    thanks

  8. I have try this tutorial above,it is work.But i was wondering can you make FontCreator.java then make it hex files? or do you need other tools??

  9. Hi,
    ¿this code only works on GLCD with Ks0108 controller? Could it work with a GLCD with s6b0107? Because I found that this controller is similar, but when I turn on the GLCD the screen is empty.

    Thanks for your answer

  10. Hi, how do I import the Project to Proteus? Zip archive only contains a Programmer ‘s Notepad Project File and a Schematic Capture File for Proteus.
    But I don’t know how I can import the source (and which of the many source and header files) to Proteus?!

    Thanks Mo

  11. Moritz, you need to compile source in to .hex and then import it to MCU model in proteus. use ks0108Test.hex from archive.
