Ambient 9 Click

Ambient 9 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 the use of Ambient 9 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient9

Example Key Functions

• ambient9_cfg_setup Config Object Initialization function.

void ambient9_cfg_setup ( ambient9_cfg_t *cfg );

• ambient9_init Initialization function.

err_t ambient9_init ( ambient9_t *ctx, ambient9_cfg_t *cfg );

• ambient9_als_data Generic function for reading ALS data from senso.

uint32_t ambient9_als_data( ambient9_t *ctx );

• ambient9_proxy_data Generic function for reading proximity data from sensor.

uint16_t ambient9_proxy_data( ambient9_t *ctx );

• ambient9_enable_data Function for enabeling sensor for ALS or proximity.

void ambient9_enable_data( ambient9_t *ctx, uint8_t als_ps );

Application Init

Initializes the driver then reads the device status and part ID. If there's any error occured it displays an appropriate message on the USB UART. After that, it enables the device mode defined by the dev_mode variable. ALS mode is selected by default.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient9_cfg_t cfg;

    uint8_t status_data;

    /** 
     * 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.

    ambient9_cfg_setup( &cfg );
    AMBIENT9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient9_init( &ambient9, &cfg );

    ambient9_generic_read( &ambient9, AMBIENT9_REG_PART_ID, &status_data, 1 );
    if ( AMBIENT9_PART_ID_VAL != status_data )
    {
        log_printf( &logger, " *****  ERROR ID!  ***** \r\n" );
        for( ; ; );
    }
    Delay_ms ( 500 );
    ambient9_generic_read( &ambient9, AMBIENT9_REG_MAIN_STATUS, &status_data, 1 );
    if ( AMBIENT9_POWER_ON == ( status_data & AMBIENT9_POWER_ON ) )
    {
        log_printf( &logger, " *****  ERROR POWER ON!  ***** \r\n" );
        for( ; ; );
    }
    
    dev_mode = AMBIENT9_ALS;
    ambient9_enable_data( &ambient9, dev_mode );  

    log_printf( &logger, " ***** APP TASK ***** \r\n" );
    Delay_ms ( 500 );
}

Application Task

Depending on the selected device mode, it reads an ambient light sensor or proximity data and displays the results on the USB UART every 100ms.

void application_task ( void )
{
    uint16_t proxy_data;
    uint32_t als_data;

    if ( AMBIENT9_ALS == dev_mode )
    {
        als_data = ambient9_als_data( &ambient9 );
        log_printf( &logger, " - ALS data: %lu \r\n", als_data );
    }
    else if ( AMBIENT9_PROXY == dev_mode )
    {
        proxy_data = ambient9_proxy_data( &ambient9 );
        log_printf( &logger, " - Proximity data: %u \r\n", proxy_data );
    }
    Delay_ms ( 100 );
}

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.
