How the system works

The demonstration board functionality can be tested with or without the container. In fact,

even if no container is connected to the demonstration board through the rubber tube, all

signals are clearly visible by means of a scope. Pressure and temperature can also be read

in real-time by connecting the demonstration board to an ST debugging tool with SWIM

interface.

Startup

After powering up the demonstration board, the RUN LED turns on, indicating that the

system is working correctly. The OFS LED blinks, indicating that the pressure reference has

not been set yet. The LED bar is off.
