Ambient 9 Click is a compact add-on board that contains an integrated ambient light sensing and proximity detector with IR LED in an optical module. This board features the APDS-9160-003, digital ALS, and IR sensing, an IR LED, and a complete proximity sensing solution from Broadcom Limited, that is fit to be used under a small aperture of the devices cover windows. It has a wide dynamic range, the proximity detection feature operates well from bright sunlight to dark rooms, and both the PS and ALS functions independently provides maximum flexibility in applications.

Click library

  • Author : MikroE Team
  • Date : Jul 2020.
  • Type : I2C type

Software Support

We provide a library for the Ambient9 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Ambient9 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ambient9_cfg_setup ( ambient9_cfg_t *cfg );

  • Initialization function.

    AMBIENT9_RETVAL ambient9_init ( ambient9_t ctx, ambient9_cfg_t cfg );

Example key functions :

  • Generic function for reading ALS data from senso

    uint32_t ambient9_als_data ( ambient9_t *ctx );

  • Generic function for reading proximity data from sensor

    uint16_t ambient9_proxy_data ( ambient9_t *ctx );

  • Function for enabeling sensor for ALS or proximity

    void ambient9_enable_data ( ambient9_t *ctx, uint8_t als_ps );

Examples Description

This example demonstrates the use of Ambient 9 Click board.

The demo application is composed of two sections :

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 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
