EXAMPLE #1.

#include <SPI.h>
#include <InvIoT_U1.h>

InvIoT_U1 lcd(A0,A1);
aIoTMenu menu;           //Create menu type aIoTMenu

void VOID(){}

MENU menuOptions[]={                       //All the items in array start with 0. First byte declares the Menu Group. Menu Group 0 is the root menu.

{0,"Menu With SubMenus",'t',VOID,0},      // Title of this Menu. Declare with the 't'. Printed on top of LCD.
 {0,"Print Hello      ",'f',helloWorld,0}, // run 'helloWorld' function. Its a 'f' type. Your 1st choice in the menu. Retrun to Root Menu (0) when exit 'helloWorld' function.
 {0,"Print test       ",'f',printTest,0},       // run 'turnLedRed' function. Its a 'f' type. Your 2nd choice in the menu. Retrun to Root Menu (0) when exit 'turnLedRed' function.

{255,"",' ',VOID,0},                             //End of Menu.
};

//********************* SETUP  and  LOOP   **************
void setup() {   
menu.menu=menuOptions;                   //Set menuOptions array to menu
menu.init(')',sizeof(menuOptions),lcd);  //Initialize menu. Character to use for cursor is '>'. Everything is send to lcd
}

void loop() {
 menu.runMenu();      // in the loop run menu all the time. It checks for rotary or button action.
}

//*********************  MENU FUNCTIONS    **************
void helloWorld(){
  lcd.clear();
  lcd.print("Hello Menu");
  delay(2000);
}
void printTest(){
  lcd.clear();
  lcd.print("test");

}
