TempHum 13 Click

TempHum 13 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 demo shows basic TempHum13 Click functionality - temperature and humidity measurement.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempHum13

Example Key Functions

• temphum13_cfg_setup Config Object Initialization function.

void temphum13_cfg_setup ( temphum13_cfg_t *cfg );

• temphum13_init Initialization function.

err_t temphum13_init ( temphum13_t *ctx, temphum13_cfg_t *cfg );

• temphum13_default_cfg Click Default Configuration function.

void temphum13_default_cfg ( temphum13_t *ctx );

• temphum13_get_humidity This function calculates humidity.

float temphum13_get_humidity ( temphum13_t *ctx );

• temphum13_get_temperature This function calculates current temperature.

float temphum13_get_temperature ( temphum13_t *ctx );

• temphum13_change_resolution This function sets Click measurement resolution.

uint8_t temphum13_change_resolution ( temphum13_t *ctx, uint8_t measurement_resolution );

Application Init

Initialize device and driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum13_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.

    temphum13_cfg_setup( &cfg );
    TEMPHUM13_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum13_init( &temphum13, &cfg );
    temphum13_default_cfg( &temphum13 );
}

Application Task

Measure temperature and humidity values on every 0,5 seconds and log them to UART Terminal if they are valid.

void application_task ( void )
{
    temperature = temphum13_get_temperature( &temphum13 );
    humidity = temphum13_get_humidity( &temphum13 );
    
    if (temperature != 65536.0)
    {
        log_printf( &logger, "\r\n> Temperature : %.2f C", temperature );
    }

    if (humidity != 65536.0)
    {       
        log_printf( &logger, "\r\n> Humidity    : %.2f%%RH\r\n", humidity );
    } 

    Delay_ms ( 500 );
}

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.
