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 device part ID data. The user also has the function for RUN and STOP procedure and function for reset device.

Key functions:

• float temphum6_readTemperature(uint8_t tempIn) - Functions for read Temperature data.
• float temphum6_readRelativeHuminidy() - Functions for read Relative Huminidy data.
• void temphum6_reset() - Functions for reset device.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes I2C module.
• Application Initialization - Initialization driver init and reset device and read Part ID.
• Application Task - (code snippet) - Reads Temperature and Huminidy data and logs this data to USBUART every 1sec.

void applicationTask()
{
    char demoText[50];
    float TEMP;
    float HUM;

    TEMP = temphum6_readTemperature(_TEMPHUM6_TEMP_IN_CELSIUS);
    FloatToStr(TEMP,demoText);
    mikrobus_logWrite("Temperature is  ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" C", _LOG_LINE);
    
    HUM = temphum6_readRelativeHuminidy();
    FloatToStr(HUM,demoText);
    mikrobus_logWrite("Huminidy is ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" %RH", _LOG_LINE);
    
    mikrobus_logWrite("------------------", _LOG_LINE);
    Delay_ms( 1000 );
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB 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.
