HDC1000 Click

HDC1000 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

Demo application code is used for measuring temperature and humidity.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HDC1000

Example Key Functions

• hdc1000_cfg_setup Config Object Initialization function.

void hdc1000_cfg_setup ( hdc1000_cfg_t *cfg );

• hdc1000_init Initialization function.

err_t hdc1000_init ( hdc1000_t *ctx, hdc1000_cfg_t *cfg );

• hdc1000_default_cfg Click Default Configuration function.

void hdc1000_default_cfg ( hdc1000_t *ctx );

• hdc1000_default_cfg This function executes default configuration for HDC1000 Click.

 hdc1000_default_cfg ( &hdc1000 );

• hdc1000_get_temperature_data This function gets temperature data from the HDC1000 sensor.

 hdc1000_get_temperature_data ( &hdc1000 );

• hdc1000_get_humidity_data This function gets humidity data from the HDC1000 sensor.

 hdc1000_get_humidity_data ( &hdc1000 );

Application Init

AppInit is used for Logger and Click initialization.

void application_init ( void )
{
    log_cfg_t log_cfg;
    hdc1000_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_printf( &logger, "---- Application Init ---- \r\n\n" );

    //  Click initialization.

    hdc1000_cfg_setup( &cfg );
    HDC1000_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hdc1000_init( &hdc1000, &cfg );
    
    hdc1000_default_cfg( &hdc1000 );
    log_printf( &logger, "---- Start measurement ---- \r\n\n" );
    Delay_ms ( 1000 );
    
}

Application Task

This is an example which demonstrates the usage of HDC1000 Click board. HDC1000 measure temperature and humidity, and calculate dewpoint value from the HDC1000 sensor.

void application_task ( void )
{
    temperature = hdc1000_get_temperature_data( &hdc1000 );
    log_printf( &logger, " Temperature : %f C \r\n", temperature );
    
    humidity = hdc1000_get_humidity_data( &hdc1000 );
    log_printf( &logger, " Humidity : %f % \r\n", humidity );

    log_printf( &logger, "----------------------------------- \r\n" );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.
