Color 9 Click

Color 9 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.

• Date : Dec 2019.
• Type : I2C type

Software Support

Example Description

This example reads data from the sensor, and then logs IR, green, blue and red measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color9

Example Key Functions

• color9_cfg_setup Config Object Initialization function.

void color9_cfg_setup ( color9_cfg_t *cfg );

• color9_init Initialization function.

err_t color9_init ( color9_t *ctx, color9_cfg_t *cfg );

• color9_get_green This function gets Green measurement reading.

uint32_t color9_get_green ( color9_t* ctx );

• color9_get_blue This function gets Blue measurement reading.

uint32_t color9_get_blue ( color9_t* ctx );

• color9_get_red This function gets Red measurement reading.

uint32_t color9_get_red ( color9_t* ctx );

Application Init

Initialize the driver and test if the sensor is present. If the ID read from the sensor is correct execute the initialization procedure.

void application_init ( void )
{
    log_cfg_t log_cfg;
    color9_cfg_t cfg;

    /** 
     * 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.

    color9_cfg_setup( &cfg );
    COLOR9_MAP_MIKROBUS( cfg, MIKROBUS_POSITION_COLOR9 );
    color9_init( &color9, &cfg );

    ID = color9_read( &color9, COLOR9_PART_ID );

    if ( ID == 0xB2 )
    {
        log_printf( &logger, "Register ID 0x%x\r\n", ID );
        color9_meas_rate( &color9, COLOR9_LS_MEAS_BITWIDTH_13, COLOR9_LS_MEAS_RATE_1000ms );
        color9_reg_ctrl( &color9, COLOR9_MAIN_CTRL_CS_MODE | COLOR9_MAIN_CTRL_LS_EN );
    }
    else
    {
        log_printf( &logger, "Error\r\n" );
        while ( 1 );
    }
}

Application Task

Wait for the color data to be available then read the data and send it to the serial port.

void application_task ( void )
{
    conv_complete = color9_get_status_reg( &color9 );

    if ( conv_complete & 0x08 )
    {
        conv_complete = 0;
        measurement_data = color9_get_Ir( &color9 );
        log_printf( &logger, "Ir: %d\r\n", measurement_data );

        
        measurement_data = color9_get_green( &color9 );
        log_printf(&logger, "Green: %d\r\n", measurement_data);

        measurement_data = color9_get_blue( &color9 );
        log_printf(&logger, "Blue: %d\r\n", measurement_data);

        measurement_data = color9_get_red( &color9 );
        log_printf(&logger, "Red: %d\r\n", measurement_data);

    }
}

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.
