Color 12 Click

Color 12 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 12 Click driver. The demo application sets sensor configuration and reads and displays RGB/IR measurement results.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color12

Example Key Functions

• color12_cfg_setup Config Object Initialization function.

void color12_cfg_setup ( color12_cfg_t *cfg );

• color12_init Initialization function.

err_t color12_init ( color12_t *ctx, color12_cfg_t *cfg );

• color12_default_cfg Click Default Configuration function.

err_t color12_default_cfg ( color12_t *ctx );

• color12_get_color_data Color 12 gets the color measurement result function.

err_t color12_get_color_data ( color12_t *ctx, color12_color_sel_t color_sel, uint16_t *color_data );

• color12_set_config Color 12 sets the configuration function.

err_t color12_set_config ( color12_t *ctx, color12_config_t config );

• color12_get_config Color 12 gets the configuration function.

err_t color12_get_config ( color12_t *ctx, color12_config_t *config );

Application Init

Initialization of I2C module and log UART. After the driver init, the app executes a default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    color12_cfg_t color12_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.
    color12_cfg_setup( &color12_cfg );
    COLOR12_MAP_MIKROBUS( color12_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == color12_init( &color12, &color12_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( COLOR12_ERROR == color12_default_cfg ( &color12 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    log_printf( &logger, " ---------------------- \r\n" );
    Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Color 12 Click board™. Reads and displays the results of the RGB/IR measurements. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    if ( COLOR12_OK == color12_get_color_data( &color12, COLOR12_DATA_RED, &color_data ) )
    {
        log_printf( &logger, " Red : %u\r\n", color_data );
    }
    
    if ( COLOR12_OK == color12_get_color_data( &color12, COLOR12_DATA_GREEN, &color_data ) )
    {
        log_printf( &logger, " Green : %u\r\n", color_data );
    }
    
    if ( COLOR12_OK == color12_get_color_data( &color12, COLOR12_DATA_BLUE, &color_data ) )
    {
        log_printf( &logger, " Blue : %u\r\n", color_data );
    }
    
    if ( COLOR12_OK == color12_get_color_data( &color12, COLOR12_DATA_IR, &color_data ) )
    {
        log_printf( &logger, " IR : %u\r\n", color_data );
    }
    log_printf( &logger, " ---------------------- \r\n" );
    Delay_ms ( 1000 );
}

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.
