2.4 Game Controller Calibration Process

For optimal performance, the Game Controller's analog inputs must be calibrated. When the

Game Controller goes through the calibration process, it will memorize the unique characteristics

of the potentiometers and joysticks ensuring that the full range of resolution will be obtained. The

calibration constants are stored in the PSoC™ FLASH memory and will be loaded every time the

system is used.

Calibration is initiated by pressing and holding the Enter key at the same time that the Game Con-

troller power is turned ON. The Bank of LEDs (LED0-LED7) will display the raw output of the chan-

nel being calibrated in 8-bit binary format. Calibration requires each potentiometer and joystick to

be exercised over its full range of movement. The potentiometers must be turned fully clockwise

and counter clockwise. The joysticks must be moved fully left and right (X-direction) and up and

down (Y-direction). To advance the calibration process to the next potentiometer or joystick after

exercising the current channel, press the Up key on the keypad. Channels are calibrated in the fol-

lowing order (observe the silk-screen labels for each input device):

1. RIGHT JOY STICK (X-direction)

2. LEFT JOY STICK (X-direction)

3. POT B

4. POT D

5. RIGHT JOY STCK (Y-direction)

6. LEFT JOY STICK (Y-direction)

7. POT A

8. POT C

9. POT F

10. POT H

11. POT E

12. POT G

Pressing the '8' key after calibrating the last channel causes the calibration factors to be stored into

FLASH and the Game Controller will return to the connected state.
