Library Description

The library covers all the necessary functions that enables the usage of the OLED Switch click.
It initializes and defines the SPI driver and drivers that offer a choice for applying different types of settings and for drawing images on the OLED display.

Key functions:

• void oledswitch_displayNormalMode() - Function is used to enable display normal mode.
• void oledswitch_draw565Img( const uint8_t *img, uint16_t imgSize ) - Function takes a 565 formatted array and writes it to the OLED switch's memory.
• void oledswitch_scrollingSetup( scroll_t setup ) - Function is used to set up the OLED Switch click for scrolling.

Examples description

The application is composed of three sections :

• System Initialization - Initializes SPI module, LOG and GPIO structures, sets CS, RST and PWM pins as output and INT pin as output.
• Application Initialization - Initalizes SPI driver and OLED Switch click, deacticates Scrolling and draws first image.
• Application Task - Shows basic capabilities of OLED Switch click by changing color of the OLED screen once per second.

void applicationTask()
{
    oledswitch_draw565Img( _OLEDSWITCH_BMP_RED, _OLEDSWITCH_IMG_SIZE );
    Delay_ms( 1000 );
    oledswitch_draw565Img( _OLEDSWITCH_BMP_GREEN, _OLEDSWITCH_IMG_SIZE );
    Delay_ms( 1000 );
    oledswitch_draw565Img( _OLEDSWITCH_BMP_BLUE, _OLEDSWITCH_IMG_SIZE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• SPI
• UART
• Conversions

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.
