DioneOS event type is a compact data type designed for communication between parts of the firmware (i.e. threads, ISRs). Such a type is easy to be managed and copied, control of its lifetime is also simplified.

The events can be stored in specific ring buffer adapted to this data type (ring_buffer_ev.h).
