Ambient 25 Click

Ambient 25 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.

• Type : I2C type

Software Support

Example Description

This example demonstrates the use of Ambient 25 Click by reading and displaying the values from two modulator channels.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient25

Example Key Functions

• ambient25_cfg_setup This function initializes Click configuration structure to initial values.

  void ambient25_cfg_setup ( ambient25_cfg_t *cfg );

• ambient25_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t ambient25_init ( ambient25_t *ctx, ambient25_cfg_t *cfg );

• ambient25_default_cfg This function executes a default configuration of Ambient 25 Click board.

  err_t ambient25_default_cfg ( ambient25_t *ctx );

• ambient25_get_int_pin This function returns the INT pin logic state.

  uint8_t ambient25_get_int_pin ( ambient25_t *ctx );

• ambient25_read_data This function checks if the als measurement data are ready for all channels and reads them.

  err_t ambient25_read_data ( ambient25_t *ctx, ambient25_data_t *data_out );

Application Init

Initializes the driver and performs the Click default configuration which sets the ALS gain level to 32x and 4x for modulators 0 and 1.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    ambient25_cfg_t ambient25_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    ambient25_cfg_setup( &ambient25_cfg );
    AMBIENT25_MAP_MIKROBUS( ambient25_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == ambient25_init( &ambient25, &ambient25_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( AMBIENT25_ERROR == ambient25_default_cfg ( &ambient25 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Waits for a data ready interrupt then reads data from two modulator channels and displays the results on the USB UART every 200ms approximately.

void application_task ( void )
{
    ambient25_data_t als_data;
 
    // Wait for a data ready interrupt
    while ( ambient25_get_int_pin ( &ambient25 ) );
 
    if ( AMBIENT25_OK == ambient25_read_data ( &ambient25, &als_data ) )
    {
        log_printf ( &logger, "\r\n ALS data 0: " );
        if ( AMBIENT25_ALS_DATA_SATURATION != als_data.als_data_0 )
        {
            log_printf ( &logger, "%u", als_data.als_data_0 );
        }
        else
        {
            log_printf ( &logger, "SATURATION" );
        }
        log_printf ( &logger, "\r\n ALS data 1: " );
        if ( AMBIENT25_ALS_DATA_SATURATION != als_data.als_data_1 )
        {
            log_printf ( &logger, "%u", als_data.als_data_1 );
        }
        else
        {
            log_printf ( &logger, "SATURATION" );
        }
        log_printf ( &logger, "\r\n" );
    }
}

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.
