Ambient 3 click

Ambient 3 Click is calibrated XYZ chromatic smart lighting director, providing the measurement data in digital format over the I2C interface. It utilizes the AS7225, a miniature light sensor with UART and I2C interfaces. Packed in a small casing, this sensor can provide calibrated for life nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

We provide a library for the Ambient3 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 Ambient3 Click driver.

Standard key functions :

• Config Object Initialization function.

  void ambient3_cfg_setup ( ambient3_cfg_t *cfg );

• Initialization function.

  AMBIENT3_RETVAL ambient3_init ( ambient3_t ctx, ambient3_cfg_t cfg );

• Click Default Configuration function.

  void ambient3_default_cfg ( ambient3_t *ctx );

Example key functions :

• This function reads device temperature.

  uint8_t ambient3_get_device_temperature( ambient3_t *ctx );

• This function reads data in LUX.

  uint16_t ambient3_get_data_in_LUX( ambient3_t *ctx );

• This function reads CCT data in K. uint16_t ambient3_get_cct_data ( ambient3_t *ctx );

Examples Description

This example demonstrates the use of Ambient 3 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient3_cfg_t cfg;

    /** 
     * 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.

    ambient3_cfg_setup( &cfg );
    AMBIENT3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient3_init( &ambient3, &cfg );
    ambient3_default_cfg( &ambient3 );
    Delay_ms ( 100 );
}

Application Task

Reads the device temperature, and daylight in LUX and logs results to USB UART each second.

void application_task ( )
{
    temperature = ambient3_get_device_temperature( &ambient3 );
    log_printf( &logger, " - Device temperature in Celsius : %u\r\n", ( uint16_t ) temperature );

    data_lux = ambient3_get_data_in_lux( &ambient3 );
    log_printf( &logger, " - Light in LUX : %u\r\n", data_lux );
    log_printf( &logger, " --------------------\r\n" );

    Delay_ms ( 1000 );
} 

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.Ambient3

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.
