We develop the gpio part as near as possible with a pseudo class for the led and a pseudo class for the button. The led class is quite simple and help to have a good understanding of this principle. As shown in @fig:led-class-header, we create a structure for the led. A `LED_init` function is used to create a LED object by returning a pointer to this structure. Function to this class start with the same prefix `LED_` and take a pointer to the structure as parameter.
