Library Description

The library initializes and defines the I2C or SPI bus driver and drivers that offer a choice for writing data in register and reads data form register. The library includes function for read Pressure data in mBar and Temperature data in C. The user also has the function for read device ID and function for read interrupt state.

Key functions:

• float pressure11_getPressure() - Functions for pressure reading.
• float pressure11_getTemperature() - Functions for temperature reading.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes SPI module and sets CS pin as OUTPUT and INT pin as INPUT.
• Application Initialization - Initializes SPI driver and checks chip ID.
• Application Task - Reads Pressure and Temperature values and displays it on UART LOG.

void applicationTask()
{
	float Temperature;
	float Pressure;
	
	Temperature = pressure11_getTemperature();
    FloatToStr(Temperature,demoText);
    mikrobus_logWrite( "Temperature: ", _LOG_TEXT );
    mikrobus_logWrite( demoText, _LOG_TEXT );
    mikrobus_logWrite( " C", _LOG_LINE );
 
    
	Pressure = pressure11_getPressure();
    FloatToStr(Pressure,demoText);
    mikrobus_logWrite( "Pressure:  ", _LOG_TEXT );
    mikrobus_logWrite( demoText, _LOG_TEXT );
    mikrobus_logWrite( "   hPa (mBar)", _LOG_LINE );
 
    
    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 500 );
}

Other mikroE Libraries used in the example:

• I2C
• SPI
• Conversions

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.
