Color 19 Click

Color 19 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 example demonstrates the use of Color 19 Click by reading and displaying the color measurement from RGBW channels and the light intensity level in lux.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color19

Example Key Functions

• color19_cfg_setup Config Object Initialization function.

void color19_cfg_setup ( color19_cfg_t *cfg );

• color19_init Initialization function.

err_t color19_init ( color19_t *ctx, color19_cfg_t *cfg );

• color19_default_cfg Click Default Configuration function.

err_t color19_default_cfg ( color19_t *ctx );

• color19_get_int_pin This function returns the INT pin logic state.

uint8_t color19_get_int_pin ( color19_t *ctx );

• color19_read_data This function reads the color data measurement of all channels and calculates the light intensity in lux.

err_t color19_read_data ( color19_t *ctx, color19_data_t *data_out );

• color19_check_communication This function checks the communication by reading and verifying the device ID.

err_t color19_check_communication ( color19_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    color19_cfg_t color19_cfg;  /**< Click config object. */

    /** 
     * 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.
    color19_cfg_setup( &color19_cfg );
    COLOR19_MAP_MIKROBUS( color19_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == color19_init( &color19, &color19_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( COLOR19_ERROR == color19_default_cfg ( &color19 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Waits for a data ready interrupt then reads the color measurement from RGBW channels and the light intensity level in lux and displays the results on the USB UART every 200ms approximately.

void application_task ( void )
{
    color19_data_t color_data;

    // Wait for a data ready interrupt
    while ( color19_get_int_pin ( &color19 ) );

    if ( COLOR19_OK == color19_read_data ( &color19, &color_data ) )
    {
        log_printf ( &logger, "RED: %lu\r\n", color_data.red );
        log_printf ( &logger, "GREEN: %lu\r\n", color_data.green );
        log_printf ( &logger, "BLUE: %lu\r\n", color_data.blue );
        log_printf ( &logger, "WHITE: %lu\r\n", color_data.white );
        log_printf ( &logger, "LUX: %lu\r\n\n", color_data.lux );
    }
}

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.
