Ambient 26 Click

Ambient 26 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 demonstrates how to read the ambient light level (ALS in lux) and UV index values using the Ambient 26 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient26

Example Key Functions

• ambient26_cfg_setup This function initializes Click configuration structure to initial values.

void ambient26_cfg_setup ( ambient26_cfg_t *cfg );

• ambient26_init This function initializes all necessary pins and peripherals used for this Click board.

err_t ambient26_init ( ambient26_t *ctx, ambient26_cfg_t *cfg );

• ambient26_default_cfg This function executes a default configuration of Ambient 26 Click board.

err_t ambient26_default_cfg ( ambient26_t *ctx );

• ambient26_get_als_lux This function calculates the ALS illuminance in lux from the raw ALS data.

err_t ambient26_get_als_lux ( ambient26_t *ctx, float *als_lux );

• ambient26_get_uv_index This function calculates the UV index value from the raw UVS data.

err_t ambient26_get_uv_index ( ambient26_t *ctx, float *uvi );

Application Init

Initializes the logger and the Ambient 26 Click driver, then applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ambient26_cfg_t ambient26_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.
    ambient26_cfg_setup( &ambient26_cfg );
    AMBIENT26_MAP_MIKROBUS( ambient26_cfg, MIKROBUS_POSITION_AMBIENT26 );
    if ( I2C_MASTER_ERROR == ambient26_init( &ambient26, &ambient26_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( AMBIENT26_ERROR == ambient26_default_cfg ( &ambient26 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Continuously reads ALS and UV index values and logs them to the UART terminal.

void application_task ( void )
{
    float als_lux = 0;
    float uv_index = 0;
    if ( AMBIENT26_OK == ambient26_get_als_lux ( &ambient26, &als_lux ) )
    {
        log_printf ( &logger, " ALS lux: %.1f\r\n", als_lux );
    }
    if ( AMBIENT26_OK == ambient26_get_uv_index ( &ambient26, &uv_index ) )
    {
        log_printf ( &logger, " UV index: %.3f\r\n\n", uv_index );
    }
}

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.
