Color 14 Click

Color 14 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 : Luka Filipovic
• Date : Aug 2021.
• Type : I2C type

Software Support

Example Description

This application showcases ability of Click board to read RGB and IR data from device. Also it can be configured to read proximity data and ALS data in lux units.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color14

Example Key Functions

• color14_cfg_setup Config Object Initialization function.

void color14_cfg_setup ( color14_cfg_t *cfg );

• color14_init Initialization function.

err_t color14_init ( color14_t *ctx, color14_cfg_t *cfg );

• color14_get_rgb_ir Read color data from device.

err_t color14_get_rgb_ir ( color14_t *ctx, color14_color_t *color_data );

• color14_get_als Read lux data from device.

err_t color14_get_als ( color14_t *ctx, float *als_data );

• color14_get_proximity Read proximity data from device.

err_t color14_get_proximity ( color14_t *ctx, uint16_t *ps_data );

Application Init

Application Init

Initialization of host communication modules (UART, I2C) and additonal pin. Read and check device ID, selects example and configures device for it.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    color14_cfg_t color14_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.
    color14_cfg_setup( &color14_cfg );
    COLOR14_MAP_MIKROBUS( color14_cfg, MIKROBUS_1 );
    err_t init_flag = color14_init( &color14, &color14_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    uint8_t temp_data = 0;
    init_flag = color14_generic_read( &color14, COLOR14_REG_PART_ID, &temp_data, 1 );

    {
        log_error( &logger, " ID" );
        log_info( &logger, " Please, run program again... " );

    if ( COLOR14_EXAMPLE_PS_LS == example_type )
    {
        //Configure proximity data to 11 bit
        color14_generic_read( &color14, COLOR14_REG_PS_MEASRATE, &temp_data, 1 );
        temp_data |= 0x18;
        color14_generic_write( &color14, COLOR14_REG_PS_MEASRATE, &temp_data, 1 );
    }
    
    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Depending of selected example in task proximity and als data will be read from device, or it will show ADC value for red, green, blue and ir data from device.

void application_task ( void ) 
{
    switch ( example_type )
    {
        case COLOR14_EXAMPLE_PS_LS:
        {
            color14_proximity_als_example( );
            break;
        }
        case COLOR14_EXAMPLE_RGB:
        {
            color14_rgb_example( );
            break;
        }
        default:
        {
            log_error( &logger, " Select example!" );
            break;
        }
    }
    Delay_ms ( 500 );
}

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.
