Automatic Joystick Calibration
There are two methods for calibrating the joysticks:
The automatic method is the simplest and is based on the controller learning the
joysticks parameters using the simple training sequence described below.
The manual method lets you enter actual timing numbers directly in the controllers
flash memory using your PC running the Roborun configuration utility. This method
is described in Loading, Changing Controller Parameters on page 185.
Automatic Joystick Calibration
To calibrate the joystick(s) follow these steps:
Press and hold the Program button while resetting or powering up the controller
After 10 seconds, the controller will enter the Program mode and flash the first
parameter (I) and its value (0 if set R/C mode)
Turn the R/C transmitter and receiver On
Press the Program button several times until the letter J is displayed. If you miss
it, keep pressing the Program button for another cycle.
When the display flashes the letter J followed by the - sign, press the Set but-
ton
When the display flashes the letter J followed by o, the controller has entered
the joystick calibration mode
Move each joystick to the desired minimum and maximum position several times
Move the joystick(s) back to the desired center position
With the joystick(s) in the center position, press the Program button to record the
change permanently in the controllers Flash memory.
Restart the controller by pressing the Reset button or cycling the power.
To reset the controller to factory default or to program the joysticks positions using numer-
ical values, see Configuring the Controller using the Switches on page 175 and Using
the Roborun Configuration Utility on page 181.
