Detailed Description

PRESS Click example.

Description

This example demonstrates the use of PRESS Click board™ by reading and displaying the pressure, temperature and Qvar measurements.

The demo application is composed of two sections :

Application Init

The initialization of I2C module and log UART. After driver initialization, the app sets the default configuration.

Application Task

The demo application shows the module working depending on the example mode:

• EXAMPLE_MODE_PRESS_TEMP: Reads and displays the Pressure [mBar] and Temperature [degree Celsius] data.
• EXAMPLE_MODE_SWIPE_SENSING: Detect a touch or a swipe. Results are being sent to the UART Terminal, where you can track their changes.

Additional Functions :

• void example_pressure_temperature ( void ) - Example pressure and temperature function.
• void example_swipe_sensing ( void ) - Example swipe sensing function.
