Library Description
This library will allow a user to read the pressure and temperature values.
Key functions:
- void pressure4_init() - Generic initialization function.
- double pressure4_getTemperature() - Returns the value of the measured temperature.
- double pressure4_getPressure() - Returns the value of the measured pressure.
Examples Description
- System Initialization - Initializes GPIO, I2C and log structures.
- Application Initialization - Configures the microcontroller for communication
and initializes the Click board. - Application Task - The pressure and temperature data is read from the sensor
and it is printed to the UART.
void applicationTask()
{
double tmp;
char text[10];
mikrobus_logWrite("Temperature : ",_LOG_TEXT);
tmp = pressure4_getTemperature();
FloatToStr(tmp,&text[0]);
mikrobus_logWrite(&text[0],_LOG_TEXT);
mikrobus_logWrite(" �C", _LOG_LINE);
mikrobus_logWrite("Pressure : ",_LOG_TEXT);
tmp = pressure4_getPressure();
FloatToStr(tmp,&text[0]);
mikrobus_logWrite(&text[0],_LOG_TEXT);
mikrobus_logWrite(" hPa", _LOG_LINE);
mikrobus_logWrite("========================",_LOG_LINE);
Delay_ms(500);
}

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.
