Initialization
The OP7100, unlike most other Rabbit Semiconductor controllers, uses the
maximum I/O and memory wait states when
states can be reduced to improve performance. The following statement
sets up the proper wait states for the standard OP7100 (using a 90 ns flash
memory).
The graphic LCD can be set up by a simple function call to
This function initializes and starts the LCD controller before supplying
voltage to the LCD screen.
The backlight is controlled by
turn off the backlight (default) or a non-zero value to turn on the backlight.
If you have an OP7100 equipped with software contrast control, call

Drawing Primitives
You can draw various objects on the LCD. Before doing any drawing,
