Libraries

[lcn]

Did you implement point, rectangle, line, strip into IC2 library ?

I would like to port these functions to get them working in SPI 4 wires mode but i can't find them in your I2C project file.

Many thanks,

Thanks,

How could i scroll a string horizontaly, is there a function to do that ?
something like this : http://www.youtube.com/watch?v=7-yIYsKFQ1Y

Yes!

Can you show me the code that scrolls a text in your library ?

Code:

void OledTicker (const char *str,char dlinok,char start,char Y)
{
char a,b,X;
char dlinst=0; 					// length of the string in characters (6 columns)
// poz - position running line (external variable)
char colcim; 					// the number of output symbols
int ptr=0,sim; 					// initialize the pointer

// calculation of the string length
    while (str[dlinst++] != 0); // length of string

// calculation of output line length for 1 once
    if (dlinst>dlinok)//lines for large size of the output window
    {
            if (poz<dlinok){ptr=0; colcim=poz; X=start+(dlinok-poz)*6;}
            else
            if (poz<dlinst){ptr=poz-dlinok; colcim=dlinok; X=start;}
            else
            {ptr=dlinst-dlinok+(poz-dlinst); colcim=dlinok-(poz-dlinst+1); X=start;}
    }
    else//lines for the equal and less than the size of the output window
    {
            if  (poz<dlinst){ptr=0;	colcim=poz; X=start+(dlinok-poz)*6;}
            else
            if  (poz<dlinok){ptr=0;	colcim=dlinst-1; X=start+(dlinok-poz)*6;}
            else
            {ptr=dlinst-dlinok+(poz-dlinst); colcim=dlinok-(poz-dlinst+1); X=start;}
    }
// Position correction output start line	
        i2c_start(ADRESOLED,0);     //
        i2c_write(0b00000000);      // control byte transfer commands
        i2c_write(0b10110000 | Y);		// installation page
        i2c_write(X & 0b00001111);		// setting column
        i2c_write((X >> 4) | 0b00010000);	//
        i2c_stop();							//

    for (b=0;b<colcim;b++) // cycle of output symbols
    {
        sim=(str[ptr+b]-0x20)*5; 	// converting the character code in the position of CG
// Read byte to byte pattern symbol and displays	
        i2c_start(ADRESOLED,0);     //
        i2c_write(0b01000000);      // control byte data transfer
        for (a=0;a<5;a++) i2c_write(SHRIFT[sim+a]);
        i2c_write(0);
        i2c_stop();
    }
    if (poz>=dlinst)
    {
        i2c_start(ADRESOLED,0);     //
        i2c_write(0b01000000);      // control byte data transfer
        for (a=0;a<5;a++) i2c_write(0);
        i2c_write(0);
        i2c_stop();
    }
    poz++;
    if (dlinst==(poz-dlinok)) poz=0; // when the pointer reaches (poz-dlinok) set to zero
}//

Thank you.

Did you implement geometry stuff such as : point, rectangle, line, strip into your IC2 library ?

[Catcatcat]

this is only a parallel interface, where it is possible not only to record but also to read data from the display memory.

Hello Catcatcat, all

Can you show me how to use ' ticker_OLED' and 'tickerB_OLED' functions with your OLED library, because it does not work for me :

I tried the following, but nothing is displayed on the screen :

Code:

        tickerB_OLED (20,5,0);
        ticker_OLED ("H",5,5,2);

I do not understand the functions arguments meaning because it is written in Russian.
Many thanks,

Hello

I need to create a custom character that will be 10x14 pixel size .

Can you tell me what software you have used to generate your 7x5 fonts ?

How can i generate a C code for my 10x14 custom character ?
I have made a monochrome BMP file so far, can you help for next steps please ?

HI
You can use LCD font maker for make fonts of size you want. I have software LCD Font Maker 3.92 is available but for limited time use not cracked version. If you need it inform me.

Hello

Yes, i'm interrested in getting LCD Font maker.

I've sent to you a PM with my email address

Many thanks
