We provide a library for the TempHum8 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

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in register and reads data form register. The library includes function for read Temperature and Relative Huminidy data and function for read/write data to user register. The user also has the function for default configuration device for measurement and function for device software reset.

Key functions :

• float temphum8_getTemperature(uint8_t tempIn) - Functions for read Temperature data
• float temphum8_getHumidity() - Functions for read Relative Huminidy data
• void temphum8_configuration(uint8_t cfg) - Functions for configuration device for measurement

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initialization driver init, chip reset and default configuration;
• Application Task - (code snippet) - Reads Temperature and Huminidy data and this data logs to USBUART every 1sec.

void applicationTask()
{
    float Temperature;
    float Humidity;
    char demoText[ 50 ];
    
    Temperature = temphum8_getTemperature(_TEMPHUM8_TEMPERATURE_IN_CELSIUS);
    FloatToStr(Temperature, demoText);
    mikrobus_logWrite(" Temperature : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" C", _LOG_LINE);
    
    Humidity = temphum8_getHumidity();
    FloatToStr(Humidity, demoText);
    mikrobus_logWrite(" Humidity    : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" RH", _LOG_LINE);
    
    mikrobus_logWrite(" ---------------------- ", _LOG_LINE);
    Delay_ms( 1000 );
}

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

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.
