Getting Started with the VEX CORTEX
Configuring the VEX Cortex for a WIRED connection using USB
|This is a guide for setting up the VEX Cortex using the USB A-to-A cable. These steps are required the first time you use your computer to program a specific VEX Cortex, or after you've upated ROBOTC to the latest verstion. Once you've successfully completed these steps you can download your own programs without revisiting them. Note: Administrative privileges are required for some of these steps.|
|ROBOTC 3.05 and later automatically installs the necessary drivers for the VEX Cortex, VEXnet Joysticks, and USB-to-Serial Programming cable. If you need to download the drivers for troubleshooting purposes, you can still find them at www.ROBOTC.net/download/cortex.|
Download ROBOTC Firmware
|The ROBOTC Firmware enables you to download ROBOTC programs to your robot and utilize the various debugger windows.
If you are also using the VEXnet Joysticks, you will need to update its firmware and establish a wireless VEXnet link between it and the Cortex.

VEXnet Remote Control Calibration
|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.

4. 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.
|One of the best ways to start working with ROBOTC and learning how to program is to look at already developed programs. ROBOTC comes with over 75 sample programs to help the programmer learn how to program their robotics controllers.
