Software Support

We provide a library for the OLED_C Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines SPI bus driver and drivers that offer a choice for writting data in registers and reading data from registers. Library includes functions for drawing a picture, pulls a rectangle and writes text on the screen. The user can set the desired font text, and adjust the background color.

Key functions :

• void oledc_init( void ) - Functions for initializes chip
• void oledc_text( uint8_t *text, uint16_t col_off, uint16_t row_off ) - Function writes text on the screen
• void oledc_image( const uint8_t *img, uint8_t column_off, uint8_t row_off ) - Function draws image on the screen

Examples Description

The application is composed of three sections :

• System Initialization - Initializes SPI module and AN pin, RST pin, CS pin, PWM pin and INT pin as output
• Application Initialization - Initializes driver init and OLED C init and sets full screen on white color with writting demo text.
• Application Task - (code snippet) - 1. Display demo rectangle 2. Display demo line 3. Display demo Image

void applicationTask()
{
    oledc_fill_screen( 0xFFFF );
    Delay_100ms();

    /* Rectangle demo*/
    oledc_rectangle( 0, 0, 96, 96, 0xF000 );
    Delay_ms( 500 );
    oledc_rectangle( 5, 5, 91, 91, 0xFF00 );
    Delay_ms( 500 );
    oledc_rectangle( 10, 10, 86, 86, 0x00F0 );
    Delay_ms( 500 );
    oledc_rectangle( 15, 15, 81, 81, 0x0F0F );
    Delay_ms( 500 );
    oledc_rectangle( 20, 20, 76, 76, 0xF000 );
    Delay_ms( 500 );
    oledc_rectangle( 25, 25, 71, 71, 0xFF00 );
    Delay_100ms();

    /* Line demo */
    oledc_rectangle( 25, 25, 71, 27, 0 );
    Delay_100ms();
    oledc_rectangle( 25, 71, 71, 73, 0 );
    Delay_100ms();
    oledc_rectangle( 25, 25, 27, 71, 0 );
    Delay_100ms();
    oledc_rectangle( 68, 25, 71, 71, 0 );
    Delay_ms( 3000 );


    /* Image demo */
    oledc_image( &me_logo_bmp[0], 0, 0 );
    Delay_ms( 2000 );
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• Conversions
• SPI

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
