LCD4884

A library for the LCD4884 Arduino shield

How to use it

Please first set your information in the header like in the example.
Now, complete the body of functions declared at the bottom, with the content you acutally want.
When you'll choose the entry in the menu, this content will be executed.

To initialize the instance :

lcd.initClass(projectName, NUM_MENU_ITEM);

To show the menu on the screen :

lcd.showMenu(menuList);

To browse menu with the buttons :

lcd.browseMenu(menuList, menuFunction);

Access 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); // Initializes 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 you can access 4 submenus.
  • Wanna use a long press on the CENTER_KEY ? Use the return value of isLongPress() 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 expected...
