Thank you for your answer but I didn't understand yet what is the different between using Command and using regular function, when both of them are implemented in the file by me? Is there any different from the microcontroller in that case?

If a module provides an interface, it must implement all the commands defined in the interface. If some other module uses the interface, the corresponding configuration file must "wire" the used interface to a module that actually implements that interface. Whenever this module calls commands from the interface, the code defined in the module to which the interface is "wired" is run. In other words, the implementation of a command can be written in a different module. A function is written as usual in C. Events are "signalled" by the the module that implements the interface. A module that uses the interface must "handle" the events signaled. A task is a piece of code (usually some heavy computation) that is "posted" in a que and executed whenever the microcontroller is free. A function can return a value, but a task always returns a void. Hope that helps. -Regards, Shankar.
