Ambient 4 Click

Ambient 4 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 application is a light intensity-sensing and measuring.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient4

Example Key Functions

• ambient4_cfg_setup Config Object Initialization function.

void ambient4_cfg_setup ( ambient4_cfg_t *cfg );

• ambient4_init Initialization function.

err_t ambient4_init ( ambient4_t *ctx, ambient4_cfg_t *cfg );

• ambient4_default_cfg Click Default Configuration function.

void ambient4_default_cfg ( ambient4_t *ctx );

• ambient4_send_command Function for send command.

void ambient4_send_command ( ambient4_t *ctx, uint8_t cmd );

• ambient4_read_data Function for read 16bit data.

uint16_t ambient4_read_data ( ambient4_t *ctx );

• ambient4_device_reset Function for device reset.

void ambient4_device_reset ( ambient4_t *ctx );

Application Init

Initialization device and power ON chip and set resolution mode.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient4_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 -----|");

    ambient4_cfg_setup( &cfg );
    AMBIENT4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient4_init( &ambient4, &cfg );
    ambient4_default_cfg ( &ambient4 );
}

Application Task

Read ambient light in [lx] and logs data to USBUART every 1 sec.

void application_task ( void )
{
    uint16_t read_value;

    //  Task implementation.
    
    read_value = ambient4_read_data( &ambient4 );
    
    log_printf( &logger, " Ambient light: %d \r\n", read_value );

    Delay_ms ( 1000);
}

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.
