kso108 based glcd library required

[vishu489]

hey i want to interface atmega16 with jhd12864e
please suggest proper library with full explanation and also circuit diagram

You can download a working library for winavr from the link it at the end of this article Arduino playground - GLCDks0108
the direct link is http://www.scienceprog.com/wp-content/uploads/2007/07/glcd_ks0108.zip

THYANK YOU

are you sure it is suitable for atmega16?

 

[alexan_e]

Yes, it works in any AVR, all you have to do is change the port pins defined in the header file to match the ones you use in your schematic.

hi alex

will you please give me a link or any document which can explain this library in detail and also i don't know how to make project by using this lib

 

[alexan_e]

There is an example code in the zip file, you can use it as a starting point and experiment.
You can also read the arduino link tutorial , I don't have any other resources.
Note that if you try to simulate the result in proteus you may see wrong data in the screen because the screen model is not operating properly.

hi alex
i want to display running text on glcd plz help me

 

[alexan_e]

I haven't done anything similar and there is no such function in the library so the only way I can think of is to rewrite the data is shifted coordinates but you are probably going to see flickering.

hi alex
i'm trying to develop my own glcd library .below i have posted my code.plz help me in writing function to display string.

 

[alexan_e]

You can look at the functions of the library I gave you and modify them

actually i already looked that but can,t understand. will u plz explain me function step by step and sorry for my poor english

 

[alexan_e]

This is the function in the above library

void ks0108Puts(char* str) {
    int x = ks0108Coord.x;
    while(*str != 0) {
        if(*str == '\n') {
            ks0108GotoXY(x, ks0108Coord.y+ks0108FontRead(ks0108Font+FONT_HEIGHT));
        } else {
            ks0108PutChar(*str);
        }
        str++;
    }
}

All it does is receive a pointer to an array of char and loop all the array members.

while(*str != 0)  // this is true until the pointer reaches the end of the array and finds a null character 
if(*str == '\n')  // this is true is there is a new line character so the function uses ks0108GotoXY to change line
ks0108PutChar(*str); // this shows the character at the pointer position by calling the function that displays a char
str++ // and this moves the pointer address to the next char of the array
