Software Support

We provide a library for the TempHum4 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

Library covers all functionalities of the click board.

Key functions :

• float temphum4_getTemperature() - Read temperature form sensor
• float temphum4_getHuminidy() - Read humidity from sensor
• void temphum4_Configuration(uint16_t _data) - Configure sensor

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module and CS pin,RST pin as OUTPUT and INT pin as INPUT
• Application Initialization - Initializes Driver init and settings chip mode ACTIVE and configuration measurement
• Application Task - (code snippet) - Reads the temperature and huminidy and logs to the USBUART every 500 ms.

void applicationTask()
{
    Temperature = temphum4_getTemperature();
    Huminidy = temphum4_getHuminidy();

    FloatToStr(Temperature,temp_txt);
    mikrobus_logWrite("Temperature : ",_LOG_TEXT);
    mikrobus_logWrite(temp_txt,_LOG_LINE);

    FloatToStr(Huminidy,hum_txt);
    mikrobus_logWrite("Huminidy : ",_LOG_TEXT);
    mikrobus_logWrite(hum_txt,_LOG_LINE);

    Delay_ms( 500 );
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
