Color 17 Click

Color 17 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.

Click Library

• Author : Nenad Filipovic
• Date : Apr 2023.
• Type : I2C type

Software Support

Example Description

This library contains API for the Color 17 Click driver. This example displays CCT data, Light intensity level and the light color names.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color17

Example Key Functions

• color17_cfg_setup Config Object Initialization function.

void color17_cfg_setup ( color17_cfg_t *cfg );

• color17_init Initialization function.

err_t color17_init ( color17_t *ctx, color17_cfg_t *cfg );

• color17_default_cfg Click Default Configuration function.

err_t color17_default_cfg ( color17_t *ctx );

• color17_get_cct Color 17 gets correlated color temperature data function.

err_t color17_get_cct ( color17_t *ctx, float *cct, float *light_intensity );

• color17_get_measurement Color 17 gets light and color measurement data function.

err_t color17_get_measurement ( color17_t *ctx, uint32_t *adc_codes );

• color17_set_config Color 17 set the configuration function.

err_t color17_set_config ( color17_t *ctx, color17_config_t config );

Application Init

Initialization of I2C module and log UART. After driver initialization, default settings turn on the device.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    color17_cfg_t color17_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.
    color17_cfg_setup( &color17_cfg );
    COLOR17_MAP_MIKROBUS( color17_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == color17_init( &color17, &color17_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( COLOR17_ERROR == color17_default_cfg ( &color17 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Color 17 Click board™. Reads and displays the correlated color temperature and Light intensity level. This example also detects and displays the light color names. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    if ( COLOR17_OK == color17_get_cct( &color17, &cct, &light_intensity ) )
    {
        log_printf( &logger, " CCT: %.2f\r\n", cct );
        log_printf( &logger, " LIL: %.2f\r\n", light_intensity );
        log_printf( &logger, " - - - - - - -  - - - - \r\n" );
        color17_display_color( );
    }
    log_printf( &logger, " ----------------------\r\n" );
    Delay_ms ( 1000 );
}

Note

Color detection is obtained based on the analysis of calculate the correlated color temperature (CCT) data and the CIE 1931 chromaticity diagram. For more details please refer to the OPT4048 High Speed High Precision Tristimulus XYZ Color Sensor datasheet OPT4048 datasheet.

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.
