2.2 Demonstration Program on Power-Up
A repeating sequence of graphics and messages in various languages will be displayed on
the LCD, and the LEDs will flash on and off in sequence when power is first applied to the
OP6800. Try pressing the buttons on the keypad. The LED immediately above that button
will light up, and if you pressed one of the keys in the top row of the keypad, the corre-
sponding LED on the Demonstration Board will light up. Similarly, if you press one of the
switches on the Demonstration Board, the corresponding LED on the Demonstration
Board and on the OP6800 will light up.
Note that the programming cable does not have to be connected for this demonstration.
This demonstration will be replaced by a new program when the programming cable is
attached and the new program is compiled and run. The demonstration is available for
future reference in the Dynamic C
directory as
SAMPLES\LCD_KEYPAD\122x32_1x7

2.3 Display Contrast Adjustment
The LCD contrast is preset at the factory. If you need to adjust the contrast for optimum
display of graphics and messages, you may adjust the potentiometer at R4 located as
shown in Figure 5. Note that OP6800 units sold before 2004 did not have any provision to
adjust the contrast.
