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 set device mode. The user also has the function for repeat measurement.

Key functions:

• float temphum10_getHumidity() - Functions for read Relative Huminidy data.
• float temphum10_getTemperature() - Functions for read Temperature data
• void temphum10_repeatMeasurement(uint8_t average) - Functions for repeat measurement.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes I2C module and sets CS pin as OUTPUT.
• Application Initialization - Initialization driver init and sets device mode.
• Application Task - (code snippet) - Reads Temperature and Humidity data and logs this data to USBUART every 1 sec.

void applicationTask()
{
    temphum10_repeatMeasurement(_TEMPHUM10_AM_TIMES_AVERAGE_MODE_2 | _TEMPHUM10_AM_TEMP_AVERAGE_MODE_TIMES_16);
    
    Temperature = temphum10_getTemperature();
    Humidity = temphum10_getHumidity();
    
    FloatToStr(Temperature, demoText);
    mikrobus_logWrite(" Temperature : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);

    FloatToStr(Humidity, demoText);
    mikrobus_logWrite(" Humidity : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);

    mikrobus_logWrite("---------------------", _LOG_LINE);

    Delay_1sec();
}

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.
