Ambient Click

Ambient 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.

Click Library

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

Software Support

Example Description

This application turns light intensity into voltage.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ambient

Example Key Functions

• ambient_cfg_setup Config Object Initialization function.

void ambient_cfg_setup ( ambient_cfg_t *cfg ); 

• ambient_init Initialization function.

err_t ambient_init ( ambient_t *ctx, ambient_cfg_t *cfg );

• ambient_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

err_t ambient_read_an_pin_voltage ( ambient_t *ctx, float *data_out );

• ambient_get_light_intensity Calculates the light intensity from analog voltage measurement of the Melexis MLX75305 IC on Ambient Click board.

uint16_t ambient_get_light_intensity ( ambient_t *ctx );

Application Init

Initialization driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient_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.
    ambient_cfg_setup( &cfg );
    AMBIENT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient_init( &ambient, &cfg );

    log_info( &logger, " Application Task " );
}

Application Task

This is an example which demonstrates the use of Ambient Click board. Ambient Click reads ADC voltage once per second and converts it to light intensity [ uW/cm2 ]. Results are being sent to the USB UART where you can track their changes.

void application_task ( void )
{
    uint16_t light_intensity = ambient_get_light_intensity( &ambient );
    log_printf( &logger, " Light Intensity: %u uW/cm2\r\n\n", light_intensity );
    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.
