Robotc VEXnet Calibration Instructions

Setup

VEXnet Joystick

This document contains the procedure for calibrating the VEXnet Remote Control joysticks.

Some steps are time-sensitive, so it's recommended that you read through the instructions once

before following along.

The VEXnet Remote Control includes two joysticks (each having an X and Y-axis), 8 buttons on

the front, and 4 additional trigger buttons on the top. Inside, there is also 3-Axis accelerometer,

capable of providing X-Y-Z acceleration values. Values from the joysticks, buttons, and

accelerometer are sent as a constant stream of information over VEXnet to the robot, enabling a

user to control the robot in real-time.

To ensure that the VEXnet Remote Control sends out accurate joystick values, the joysticks must be

calibrated before their first use, and after any firmware updates are applied to the remote control.

You will need:

• A VEXnet Remote Control with batteries

• A VEX Cortex with robot battery

• A small Allen wrench (1/16" or smaller) or paper clip

1. Power on the VEXnet Remote Control and VEX Cortex. Allow them to sync over VEXnet.

Move both joysticks through their full ranges of motion. When the remote control detects that the joysticks have been fully rotated, the JOYSTICK LED stops blinking red and green, and switches to a solid green.
