User Interface

A single GLCD object is provided to control one GLCD module. It is possible to use multiple GLCDs by creating more objects.

The core object class is _GLCD, and a default object of GLCD is provided.

Setting up the GLCD requires first telling the object which pins are connected to which IO ports. At the moment all pins (including reset) need to be connected.

GLCD.begin(DI,RW,E,D0,D1,D2,D3,D4,D5,D6,D7,CS1,CS2,RES);

This will initialise the GLCD and get it ready for operation.

After any drawing operations have been performed it is necessary to do an "update" of the screen:

GLCD.update();

This will push the new frame to the display so you can see your changes.

There are three basic class of methods in the GLCD object:

• Drawing Functions
  • [setPixel]
  • [clearPixel]
  • [draw]
• Text Functions]
  • [setCursor]
  • [print]
  • [setGCursor]
  • [gText]
• Control Functions
  • [begin]
  • [update]
  • [cls]
  • [scrollUp]
