hudakz 0:f7514c3f33b6 2 * An example of using the Menu library - Simple Menu system with push buttons.
hudakz 0:f7514c3f33b6 3 *
hudakz 0:f7514c3f33b6 4 * The Menu library was created to facilitate designs with a display and push buttons.
hudakz 0:f7514c3f33b6 5 * - number of menus and push buttons is practically not limited by the software
hudakz 0:f7514c3f33b6 6 * - function of individual push buttons varies depending on the selected menu
