Joystick Test:
This test is used to verify the operation of the Joystick hardware and circuitry. This test has been designed
to display the movement of the Joystick on the LCD display. During the test, the Joystick must be moved
along the outside edges (farthest from the center) a minimum of two times.
When the test is executed, the following screen will appear on the LCD display:
The outer (White) brackets in the corners of the LCD display represent the lower limits of the Joystick Test.
The inner (Red) brackets on the LCD display represent the upper limits of the Joystick Test.
During the test, an image (box) is drawn in the center of the LCD display as the Joystick is moved, which
represent the values read from Joystick A/D converter. The image displayed in each corner of the LCD
display represents a magnified view of the four corners from the image drawn in the center of the LCD
display (as shown in the example below).
NOTE: The image drawn in the center of the LCD display should always be drawn in the same direction as
the joystick (up/down & left/right) movement. This test is useful for verifying the correct wiring of the
Joystick.
NOTE: During the test, the Meter Board RED and GRN LED's act as a level meter which displays the
values read (X/Y position) from the joysticks A/D converter (1=Min, 8=Max) for troubleshooting purposes.
