Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for read data form register. The library includes function for read Temperature data and function for read and set temperature hysteresis and limit. The user also has the function for configuration chip and read Interrupt (INT pin) state.

Key functions:

• float thermo15_getAmbientTemperatureData(uint8_t tempIn) - Ambient temperature data.
• void thermo15_setTempRegister(uint8_t tempReg, float temp) - Set temperature register.
• void thermo15_configuration(uint8_t cfgData) - Configuration register.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module and sets INT pin as INPUT.
• Application Initialization - Initializes the driver init, configures the module and reads the temperature hysteresis and limit values that are set.
• Application Task - Reads ambient temperature data and this data logs to USBUART every 1500ms.

void applicationTask()
{
    float Temperature;
    
    Temperature = thermo15_getAmbientTemperatureData( _THERMO15_TEMP_IN_CELSIUS );
    FloatToStr(Temperature, demoText);
    mikrobus_logWrite("** Temperature : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);
    
    mikrobus_logWrite( " ---------------------------- ", _LOG_LINE);
    
    Delay_ms( 1500 );
}
			

Other mikroE Libraries used in the example:

• I2C Library.
• UART Library.
• Conversions Library.

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.
