RGB Driver Click

RGB Driver Click is an RGB LED driver, capable of driving RGB LED stripes, LED fixtures and other RGB LED applications that demand an increased amount of current and voltage.

Software Support

We provide a library for the RgbDriver 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 RgbDriver Click driver.

Standard key functions :

• Config Object Initialization function.

  void rgbdriver_cfg_setup ( rgbdriver_cfg_t *cfg );

• Initialization function.

  RGBDRIVER_RETVAL rgbdriver_init ( rgbdriver_t ctx, rgbdriver_cfg_t cfg );

• Click Default Configuration function.

  void rgbdriver_default_cfg ( rgbdriver_t *ctx );

Example key functions :

• This function sets the color of the rgb LEDs through the parameters for red, green and blue.

  void rgbdriver_set_rgb_color ( rgbdriver_t *ctx, uint8_t red, uint8_t green, uint8_t blue );

• This function sets the color.

  void rgbdriver_set_color ( rgbdriver_t *ctx, uint32_t color );

• This function shut down device.

  void rgbdriver_shut_down ( rgbdriver_t *ctx );

Examples Description

This application sets the brightness over RGB value.

The demo application is composed of two sections :

Application Init

Initializes driver and logger, and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    rgbdriver_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.

    rgbdriver_cfg_setup( &cfg );
    RGBDRIVER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    rgbdriver_init( &rgbdriver, &cfg );
    Delay_ms ( 1000 );

    rgbdriver_default_cfg( &rgbdriver );
    Delay_ms ( 100 );
}

Application Task

Changes the color of RGB LED tape connected to the Click board every 2 seconds. The name of the selected color will be displayed on USB UART.

void application_task ( void )
{
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_RED_LOW_INTENSITY );
    log_printf( &logger, "\r\n--- RED ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_ORANGE_LOW_INTENSITY );
    log_printf( &logger, "--- ORANGE ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_YELLOW_LOW_INTENSITY );
    log_printf( &logger, "--- YELLOW ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_GREEN_LOW_INTENSITY );
    log_printf( &logger, "--- GREEN ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_BLUE_LOW_INTENSITY );
    log_printf( &logger, "--- BLUE ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_WHITE_LOW_INTENSITY );
    log_printf( &logger, "--- WHITE ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
    rgbdriver_set_color( &rgbdriver, RGBDRIVER_COLOR_PURPLE_LOW_INTENSITY );
    log_printf( &logger, "--- PURPLE ---\r\n" );
    Delay_1sec( );
    Delay_1sec( );
} 

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.RgbDriver

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.
