Library Description

The library initializes and defines I2C bus drivers and driver functions that offer a choice for writing data in registers and reading data from registers. The library offers the possibility of setting the upper and lower temperature limits, and the main thing is reading the ambient temperature.ADC resolution can be set to 9bit, 10bit, 11bit or 12bit, with an accuracy of 0.5 C, 0.25 C, 0.125 C or 0.0625 C. The user can adjust the state and behavior of interrupt pins in the set modes. Modes that can be set are Interrupt mode and Comparator mode..

Key functions:

float thermo7_readAmbientTemperature() - Function reads ambient temperature

void thermo7_setConfiguration(uint8_t configuration) - Function for configuration chip and measurement

void thermo7_setResolution(uint8_t resolution) - Function sets ADC resolution measurement
 

Examples Description

The application is composed of three sections:

• System Initialization - Initializes I2C module and sets INT pin as INPUT.
• Application Initialization -  Initializes driver init and configuration chip and measurement resolutions.
• Application Task - (code snippet) - Reads ambient temperature and logs to USBUART every 1 second.

void applicationTask()
{
 AmbientTemperature = thermo7_readAmbientTemperature();
 FloatToStr( AmbientTemperature, tempText );
 mikrobus_logWrite( " Ambient temperature : ", _LOG_TEXT );
 mikrobus_logWrite( tempText, _LOG_TEXT );
 mikrobus_logWrite( " °C", _LOG_LINE );
 Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

Additional notes and information

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.
