Ambient 8 Click

Ambient 8 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 collects data from the sensor, calculates the light intensity and then logs it.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient8

Example Key Functions

• ambient8_cfg_setup Config Object Initialization function.

  void ambient8_cfg_setup ( ambient8_cfg_t *cfg );

• ambient8_init Initialization function.

  err_t ambient8_init ( ambient8_t *ctx, ambient8_cfg_t *cfg );

• ambient8_default_cfg Click Default Configuration function.

  void ambient8_default_cfg ( ambient8_t *ctx );

• ambient8_set_constants This function sets constants ( gain and integration time ) for lux level calculation.

  void ambient8_set_constants ( ambient8_t* ctx );

• ambient8_get_als_data This function checks for new data by polling ALS status register.

  err_t ambient8_get_als_data ( ambient8_t* ctx, uint16_t* als_data_ch1,uint16_t* als_data_ch0 );

• This function reads and data and performs lux level calculation err_t ambient8_get_lux_level ( ambient8_t* ctx, float* lux_level, float window_factor, float IR_factor );

Application Init

Initializes device and I2C driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient8_cfg_t cfg;

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    ambient8_cfg_setup( &cfg );
    AMBIENT8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient8_init( &ambient8, &cfg );
 
    window_factor = 1.0;
    IR_factor = 0.0;
}

Application Task

Performs Lux calculation based on window and IR factor and log results.

void application_task ( void )
{
    status_flag = ambient8_get_lux_level( &ambient8, &lux_level, window_factor, IR_factor );
 
    if ( status_flag == 0 )
    {
        log_printf( &logger, "Lux level : %.2f lx\r\n", lux_level );
    }
}

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.
