Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing and reading
data in and from registers. The library includes a functions for reading temperature in Fahrenheit, Celsius 
and Kelvin scales, user can also read or set configuration and read or set overtemperature shutdown threshold and hysteresis temperature. Library also has generic read/write functions for additional read and write operations.

Key functions:

• float thermo4_readTemperatureC(); - Function reads sensor and returns result value representing current temperature in degrees centigrade.
• float thermo4_readTemperatureF();- Function reads sensor and returns result value representing current temperature in degrees fahrenheit.
• float thermo4_readTemperatureK(); - Function reads sensor and returns result value representing current temperature in kelvin.

Examples description

The application is composed of three sections:

• System Initialization - Initializes GPIO, I2C and LOG structures, set INT pin as input.
• Application Initialization -  Initalizes I2C driver and makes an initial log.
• Application Task - (code snippet) This is an example that shows the most important functions that Thermo 4 click has.

void applicationTask() 
{
    value1 = thermo4_readTemperatureC();
    Delay_10ms();
    value2 = thermo4_readTemperatureF();
    Delay_10ms();
    value3 = thermo4_readTemperatureK();
    Delay_10ms();
    
    mikrobus_logWrite( " Temperature celsius    : ", _LOG_TEXT );
    logDisplay( value1 );
    mikrobus_logWrite( degCel, _LOG_LINE );

    mikrobus_logWrite( " Temperature fahrenheit : ", _LOG_TEXT );
    logDisplay( value2 );
    mikrobus_logWrite( degFar, _LOG_LINE );

    mikrobus_logWrite( " Temperature kelvin     : ", _LOG_TEXT );
    logDisplay( value3 );
    mikrobus_logWrite( "K", _LOG_LINE );

    mikrobus_logWrite( "---------------------------------", _LOG_LINE );
    Delay_1sec();
}  

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversion

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
