Spectral 3 Click

Spectral 3 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.

Example Description

This example reads and processes data from Spectral 3 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Spectral3

Example Key Functions

• spectral3_cfg_setup Config Object Initialization function.

void spectral3_cfg_setup ( spectral3_cfg_t *cfg );

• spectral3_init Initialization function.

err_t spectral3_init ( spectral3_t *ctx, spectral3_cfg_t *cfg );

• spectral3_module_reset Reset module.

void spectral3_module_reset ( spectral3_t *ctx );

• spectral3_send_command Send command.

void spectral3_send_command ( spectral3_t *ctx, char *command );

• spectral3_get_data Read raw X, Y, Z and NIR data as well as two special internal registers D, & C.

void spectral3_get_data ( char *rsp, uint16_t *c_data );

Application Init

Initializes the driver and configures the sensor.

void application_init ( void )
{
    log_cfg_t log_cfg;
    spectral3_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.

    spectral3_cfg_setup( &cfg );
    SPECTRAL3_MAP_MIKROBUS( cfg, MIKROBUS_POSITION_SPECTRAL3 );
    spectral3_init( &spectral3, &cfg );

    spectral3_module_reset( &spectral3 );
    Delay_ms ( 500 );
    
    log_printf( &logger, "Configuring the sensor...\r\n" );
    spectral3_send_command( &spectral3, SPECTRAL3_CMD_AT );
    spectral3_process( );
    spectral3_send_command( &spectral3, SPECTRAL3_CMD_GAIN );
    spectral3_process( );
    spectral3_send_command( &spectral3, SPECTRAL3_CMD_MODE );
    spectral3_process( );
    log_printf( &logger, "The sensor has been configured!\r\n" );
    Delay_ms ( 1000 );
}

Application Task

Reads the values of all 6 channels and parses it to the USB UART each second.

void application_task ( void )
{
    parser_application( );
}

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.
