Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in the register and reads data from the register. The library includes the function for reading Temperature and Relative Humidity data and function for reading/writing 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 reading Temperature data
  • float temphum8_getHumidity() - Functions for reading Relative Humidity data
  • void temphum8_configuration(uint8_t cfg) - Functions for configuration device for measurement

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes I2C module
  • Application Initialization - Initialization driver init, chip reset and default configuration;
  • Application Task - (code snippet) - Reads Temperature and Humidity 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 );

}

Additional notes and information

Depending on the development board you are using, you may need USB UART clickUSB UART 2 clickor 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.
