Color 12 Click

Color 12 Click is a compact add-on board providing an accurate color-sensing solution. This board features the BU27006MUC-Z, a digital color sensor from Rohm Semiconductor with an integrated flicker sensing function. The BU27006MUC-Z can sense Red, Green, Blue (RGB), and Infrared light and efficiently convert them into digital values via the I2C interface. Its remarkable high sensitivity, wide dynamic range, and exceptional IR-cut characteristics enable precise illuminance measurement, typically up to 50klx, and accurate ambient light color temperature determination. Moreover, this sensor can effectively detect flicker noise originating from displays and room lighting, with a typical sensitivity of 10klx.

Software Support

We provide a library for the Color 12 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Color 12 Click driver.

Standard 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 );

Example key functions :

• 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 );

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.

The demo application is composed of two sections :

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 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
