This is a sample program which demonstrates the use of Pressure Click.
Program uses Pressure module LPS331AP for measuring 260-1260 mbar of pressure.
Pressure and temperature is then presented on the LCD 2 x 16 char bit.

The library covers all the necessary functions to control Pressure Click board. Library performs the communication with the device via I2C driver by writing to registers and by reading from registers. Library set/get configuration, for getting the ID, for enabling/disable device,
for measuring pressure and temperature and convert that data to pressure in mbar and temperature in degrees Celsius, etc.
Key functions:
Examples description
The application is composed of three sections:
void applicationTask() { pressure = pressure_getPressure(); Delay_10ms(); mikrobus_logWrite( " Pressure : ", _LOG_TEXT ); FloatToStr( pressure, logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( " mbar", _LOG_LINE ); temperature = pressure_getTemperature(); Delay_10ms(); mikrobus_logWrite( " Temperature: ", _LOG_TEXT ); FloatToStr( temperature, logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( degCel, _LOG_LINE ); mikrobus_logWrite( "----------------------------", _LOG_LINE ); Delay_1sec(); Delay_1sec(); Delay_1sec(); }

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
