Example Description

This application measures temperature and humidity.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempHum5

Example Key Functions

• temphum5_cfg_setup Config Object Initialization function.

void temphum5_cfg_setup ( temphum5_cfg_t *cfg );

• temphum5_init Initialization function.

err_t temphum5_init ( temphum5_t *ctx, temphum5_cfg_t *cfg );

• temphum5_start_measurement Functions for start measurement.

uint8_t temphum5_start_measurement ( temphum5_t *ctx );

• temphum5_get_temperature Functions for read Temperature data.

float temphum5_get_temperature ( temphum5_t *ctx, uint8_t temp_in );

• temphum5_get_humidity Functions for read Relative Huminidy data.

float temphum5_get_humidity ( temphum5_t *ctx );

Application Init

Initialization device init

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum5_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.

    temphum5_cfg_setup( &cfg );
    TEMPHUM5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum5_init( &temphum5, &cfg );
}

Application Task

Reads Temperature and Humidity data and this data logs to USBUART every 1 sec.

void application_task ( )
{
    float temperature;
    float humidity;
    
    temphum5_start_measurement( &temphum5 );
    
    temperature = temphum5_get_temperature( &temphum5, TEMPHUM5_TEMP_DATA_IN_CELSIUS );
                                        
    log_printf( &logger, "Temperature: %.2f C \r\n ", temperature );
    
    humidity = temphum5_get_humidity ( &temphum5 );
    log_printf( &logger, "Humidity: %f RH \r\n ", humidity );
    
    log_printf( &logger, "------------------------ \r\n " );
    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.
