LED Driver 3 Click

LED Driver 3 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This app changes color and intensity of light.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LedDriver3

Example Key Functions

• leddriver3_cfg_setup Config Object Initialization function.

void leddriver3_cfg_setup ( leddriver3_cfg_t *cfg );

• leddriver3_init Initialization function.

err_t leddriver3_init ( leddriver3_t *ctx, leddriver3_cfg_t *cfg );

• leddriver3_default_cfg Click Default Configuration function.

void leddriver3_default_cfg ( leddriver3_t *ctx );

• leddriver3_set_rgb_color This function sets the color of the rgb LEDs through the parameters for red, green and blue.

void leddriver3_set_rgb_color ( leddriver3_t *ctx, rgb_t *rgb );

• leddriver3_set_color This function sets color.

void leddriver3_set_color ( leddriver3_t *ctx, uint32_t color );

• leddriver3_set_timer This function sets timer for increase or decrease light.

void leddriver3_set_timer ( leddriver3_t *ctx, uint8_t time );

Application Init

Driver initialize.

void application_init ( void )
{
    log_cfg_t log_cfg;
    leddriver3_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 ----\r\n" );

    //  Click initialization.

    leddriver3_cfg_setup( &cfg );
    LEDDRIVER3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    leddriver3_init( &leddriver3, &cfg );
}

Application Task

Changes color and intensity of light.

void application_task ( void )
{
    rgb.red = 0x40;
    rgb.green = 0x7F;
    rgb.blue = 0x80;

    leddriver3_set_intensity( &leddriver3, LEDDRIVER3_INCREMENT | LEDDRIVER3_INTENSITY_8 );
    leddriver3_set_timer( &leddriver3, LEDDRIVER3_TIMER_8ms | LEDDRIVER3_TIMER_16ms );
    leddriver3_set_color( &leddriver3, LEDDRIVER3_COLOR_RED );
    Delay_1sec( );
    
    leddriver3_set_intensity( &leddriver3, LEDDRIVER3_CONSTANT | LEDDRIVER3_INTENSITY_16 );
    leddriver3_set_color( &leddriver3, LEDDRIVER3_COLOR_YELLOW );
    Delay_1sec( );
    leddriver3_set_color( &leddriver3, LEDDRIVER3_COLOR_BLUE );
    Delay_1sec( );

    leddriver3_set_rgb_color( &leddriver3, &rgb );
    Delay_1sec( );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
