OLED C click

OLED C click is equipped with the 96x96 high-color OLED display. It can display up to 65K/262K different colors and shades on a compact size display, based on the OLED technology.

Click library

• Author : MikroE Team
• Date : apr 2020.
• Type : SPI type

Software Support

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

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for OledC Click driver.

Standard key functions :

• Config Object Initialization function.

  void oledc_cfg_setup ( oledc_cfg_t *cfg );

• Initialization function.

  OLEDC_RETVAL oledc_init ( oledc_t ctx, oledc_cfg_t cfg );

• Click Default Configuration function.

  void oledc_default_cfg ( oledc_t *ctx );

Example key functions :

• Fill Screen.

  void oledc_fill_screen( oledc_t *ctx, uint16_t color );

• Draw BMP Image.

  void oledc_image( oledc_t ctx, const uint8_t img, uint8_t column_off, uint8_t row_off );

Examples Description

This demo demonstrates the use of the OLED C click board and the control of the OLED C display.

The demo application is composed of two sections :

Application Init

Initializes driver init and OLED C init and sets full screen on white color with writting demo text.

void application_init ( void )
{
    log_cfg_t log_cfg;
    oledc_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    oledc_cfg_setup( &cfg );
    OLEDC_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    oledc_init( &oledc, &cfg );

    oledc_default_cfg( &oledc );
    oledc_fill_screen( &oledc, 0xFFFF );

#ifndef IMAGE_MODE_ONLY
    oledc_set_font( &oledc, guiFont_Tahoma_8_Regular, 0 );
    oledc_text( &oledc, text1, 15, 10 );
    oledc_text( &oledc, text2, 5, 30 );
    oledc_text( &oledc, text3, 5, 45 );
#endif
    Delay_ms ( 1000 );
}

Application Task

This function is composed of three sections :

• Display demo rectangle.
• Display demo line.
• Display demo image.

void application_task ( void )
{
    oledc_fill_screen( &oledc, 0xFFFF );
    Delay_100ms();

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

    // Line demo 
    oledc_rectangle( &oledc, 25, 25, 71, 27, 0 );
    Delay_100ms();
    oledc_rectangle( &oledc, 25, 71, 71, 73, 0 );
    Delay_100ms();
    oledc_rectangle( &oledc, 25, 25, 27, 71, 0 );
    Delay_100ms();
    oledc_rectangle( &oledc, 68, 25, 71, 71, 0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );


    // Image demo 
    oledc_image( &oledc, mikroe_with_slogan96x96, 0, 0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.OledC

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.
