Light 6 Click

Light 6 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 : Stefan Filipovic
• Date : Mar 2026.
• Type : I2C type

Software Support

Example Description

This example demonstrates the use of the Light 6 Click board, which measures ambient light and infrared (IR) intensity. The application initializes the device and continuously reads ALS and IR data, displaying the results via UART logging.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Light6

Example Key Functions

• light6_cfg_setup This function initializes Click configuration structure to initial values.

  void light6_cfg_setup ( light6_cfg_t *cfg );

• light6_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t light6_init ( light6_t *ctx, light6_cfg_t *cfg );

• light6_default_cfg This function executes a default configuration of Light 6 Click board.

  err_t light6_default_cfg ( light6_t *ctx );

• light6_get_data This function reads the raw IR data and ambient light intensity in lux based on raw ALS data.

  err_t light6_get_data ( light6_t *ctx, float *als_data, uint16_t *ir_data );

Application Init

Initializes the logger and configures the Light 6 Click board. It establishes I2C communication and applies the default configuration settings.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    light6_cfg_t light6_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    light6_cfg_setup( &light6_cfg );
    LIGHT6_MAP_MIKROBUS( light6_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == light6_init( &light6, &light6_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( LIGHT6_ERROR == light6_default_cfg ( &light6 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Continuously reads ambient light and infrared sensor data and logs the results in lux and raw IR values, respectively. The readings are updated every 200ms.

void application_task ( void )
{
    float als_data = 0;
    uint16_t ir_data = 0;
    if ( LIGHT6_OK == light6_get_data ( &light6, &als_data, &ir_data ) )
    {
        log_printf ( &logger, " ALS Data: %.1f lux\r\n", als_data );
        log_printf ( &logger, " IR Data: %u\r\n\n", ir_data );
        Delay_ms ( 200 );
    }
}

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.
