Calibrating Analogue Joystick

The following description explains how to manually calibrate Analogue Joystick. The procedure consists of three main
steps:
1. Read sensor values and sensor supply voltage
2. Data sector preparation
3. Write parameters to PVED-CLS' EEPROM
Procedure:
Read sensor values and sensor supply voltage
•
Put PVED-CLS into "Joystick Calibration service mode"
•
Start ADC readout on CAN bus
For MAIN- and SAFETY-controller, start status message 1 @ 100ms
o
For MAIN- and SAFETY-controller, start status message 3 @ 100ms
o
•
Turn Joystick to left most position
For MAIN- and SAFETY-controller, read AD1 and AD2 and temporarily store the two values
o
•
Turn Joystick to neutral position
For MAIN- and SAFETY-controller, read AD1 and AD2 and temporarily store the two values
o
•
Measure sensor supply voltage (only needed if the 5V Sensor supply compensation is enabled (P3217 set to 255
and P3219 set to 255)
•
Turn Joystick to right most position
o For MAIN- and SAFETY-controller, read AD1 and AD2 and temporarily store the two values
