Upgrade to Full Graphic Smart Controller

[vchan3m]

Hi,

I am trying to upgrade the controller to full graphic smart controller. After changing the definition to:
//#define REPRAP_DISCOUNT_SMART_CONTROLLER

define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

I got the error message that of:
error: 'BEEPER' was not declared in this scope

Any reason why this is happened? Thanks
