Software Support

We provide a library for the TempHum5 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for TempHum5 Click driver.

Standard key functions :

• Config Object Initialization function.

  void temphum5_cfg_setup ( temphum5_cfg_t *cfg );

• Initialization function.

  TEMPHUM5_RETVAL temphum5_init ( temphum5_t ctx, temphum5_cfg_t cfg );

Example key functions :

• Functions for start measurement

  uint8_t temphum5_start_measurement ( temphum5_t *ctx );

• Functions for read Temperature data

  float temphum5_get_temperature ( temphum5_t *ctx, uint8_t temp_in );

• Functions for read Relative Huminidy data

  float temphum5_get_humidity ( temphum5_t *ctx );

Examples Description

This application measures temperature and humidity.

The demo application is composed of two sections :

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 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
