Spectral 2 Click

Spectral 2 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.

Application Init

Driver initialize, reset module and configuration measurement

void application_init ( void )
{
    log_cfg_t log_cfg;
    spectral2_cfg_t cfg;
    uint8_t cfg_data;

    /** 
     * 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.

    spectral2_init( &spectral2, &cfg );

Application Task

Reads the brightness value with R, G, B, I, O and V filter, every 1 second, and logs on to USBUART.

void application_task ( void )
{
    float f_data;

    //  Task implementation.

    log_printf( &logger, "-------------------\r\n" );

    f_data = spectral2_get_calibrated_data( &spectral2, SPECTRAL2_CALIBRATED_DATA_R );
    log_printf( &logger, "-- R ( Red data ) : %.2f \r\n", f_data );
    
    f_data = spectral2_get_calibrated_data( &spectral2, SPECTRAL2_CALIBRATED_DATA_G );
    log_printf( &logger, "-- G ( Green data ) : %.2f\r\n", f_data );
    
    f_data = spectral2_get_calibrated_data( &spectral2, SPECTRAL2_CALIBRATED_DATA_B );
    log_printf( &logger, "-- B ( Blue data ) : %.2f\r\n", f_data );
    
    f_data = spectral2_get_calibrated_data( &spectral2, SPECTRAL2_CALIBRATED_DATA_Y );
    log_printf( &logger, "-- Y ( Yellow data ) : %.2f\r\n", f_data );

    log_printf( &logger, "-- O ( Orange data ) : %.2f\r\n", f_data );
    
    f_data = spectral2_get_calibrated_data( &spectral2, SPECTRAL2_CALIBRATED_DATA_V );
    log_printf( &logger, "-- V ( Violet data ) : %.2f\r\n", f_data );
    
    Delay_1sec( );
}

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.
