You can use our free supporting software - GLCD Font Creator, and make personalized fonts, symbols, and icons for the LED matrix onboard the click. Create fonts and symbols from scratch, or by importing existing fonts on your system. It lets you modify and adjust them for your needs, apply effects and finally export them as source code for use in mikroC, mikroBasic or mikroPascal compilers.

Library Description

The library carries all functions necessary for complete control over the 7x10 B click. There is also an additional font header file which carries 5x7 letter definitions.

Key functions

• bool c7x10b_refreshDisplay( void ) - Refreshes the display; this function should be called upon as frequently as possible.
• void c7x10b_drawPixel( uint8_t row, uint8_t col )- Draws single pixel on the desired location.
• void c7x10b_drawText( char *text )- Writes the text; The first character is placed on the first LED matrix, and the second one is placed on the second LED matrix (if a there is more than one character).

The example also carries additional functions for GPIO control which are provided during driver initialization. These functions are necessary and the implementation depends on the type of development system that is used.

Examples Description

The application is composed of three sections :

• System Initialization - Initializes GPIO and SPI peripheral
• Application Initialization - Default driver initialization
• Application Task - (code snippet) a demonstration of the main functions of the library. First, the text "MikroElektronika" is scrolled, then the countdown from 0 to 30. And finally random lighting up of the LEDs - using the function c7x10b_drawPixel.

void applicationTask()
{
    bool ind;
    static bool called = false;
    int i, j;
    c7x10b_clearDisplay();
    
    if ( !called )
    {
        c7x10b_drawText( "  Mikro Elektronika" );
        c7x10b_scrollEnable( _C7X10R_SPEED_MED );
        called = true;
    }
    do
    {
        ind = c7x10b_refreshDisplay();
        c7x10b_tick();
        Delay_ms( 10 );
    
    } while( ind );
    called = false;
    
    for( i = 0; i < 11; ++i )
    {
        c7x10b_clearDisplay();
        c7x10b_drawNumber( i );
        for( j = 0; j < 30; ++j )
        {
            c7x10b_refreshDisplay();
            Delay_ms( 10 );
        }
    }
    
    // draws a few pixels
    c7x10b_clearDisplay();
    c7x10b_drawPixel( 6, 3 );
    c7x10b_drawPixel( 6, 8 );
    c7x10b_drawPixel( 2, 3 );
    c7x10b_drawPixel( 2, 8 );
    for( j = 0; j < 100; ++j )
    {
        c7x10b_refreshDisplay();
        Delay_ms( 10 );
    }
