To browse menu with the buttons:

lcd.browseMenu(menuList, menuFunction)

Access to Methods

You can use also these methods:

turnBacklightOn(true / false)
writeString(posX, posY, const char*, MENU_NORMAL / MENU_HIGHLIGHT)
writeStringBig(posX, posY, const char*, MENU_NORMAL / MENU_HIGHLIGHT)
writeChar(posX, posY, char, MENU_NORMAL / MENU_HIGHLIGHT)
writeCharBig(posX, posY, char, MENU_NORMAL / MENU_HIGHLIGHT)
clear(void)
init(void) (to initialize the screen without menu or buttons operation)

Notes

• With this configuration, you have the Name of your project written centered at the top of the screen, and access to 4 submenus.
• Wanna use a long press on CENTER_KEY ? Use the return value (bool) of getLongPress() to reach the status of last pression.
• Wanna use the status of joystick's buttons in your own code ? Compare the return value int(analogRead(0))) with LEFT_K_A , CENTER_K_A , DOWN_K_A , RIGHT_K_A , UP_K_A , K_RELEAS_A , the analogic values returned by the joystick. But careful ! The analogic value read for a position can be a bit different than the one behind the MACRO...
