Using the Cortex

Carolyn Bauer

July 21-22, 2014


Charge the Batteries

  • Before you begin any work, charge the following:

    • Both 7.2 V batteries

    • All 6 AAA batteries


Introduction to easyC® & Cortex™

Adapted from http://www.intelitekdownloads.com/easyCV4/intro.pdf and http://best.eng.auburn.edu/stored_procedures/folder-manager/create-folder.php?folder=491&parent_id=489


Cortex™ Microcontroller


Joystick


VEXNet™USB A-A Tether Cableand USB Keys


Setup for Download of Firmware to Cortex/Joystick

  • AAA batteries in joystick

  • Connect programming cable

  • Power on

  • Open easyC

  • Use same connection with Cortex microcontroller


Install easyC

  • Install easyC v4 for Cortex (Trial version) on your computer

  • Download from http://www.intelitekdownloads.com/easyCV4/


easyC®V4 Programming Software

  • Download from the website.

  • Run as Administrator to install.


Unlocking easyC®

  • Right-click easyC , Run as Administrator

  • Type in your CD Key and click Unlock.


Updating easyC®

Go to Help…Check For Updates. If you don’t have the latest version, you can download updates.


Updating Firmware on Controller and Joystick

We have done this already in 2014

  • Start…All Programs…easyC v4 For Cortex…IFI VEXNet Firmware Utility


Updating Controller and Joystick

  • Select SEARCH. If the response is Upgrade requiredthen BOOTLOADand YES.


Updating Controller and Joystick

  • Click DOWNLOAD.

  • Afterward you should see:


Updating Controller and Joystick

  • Now repeat the entire SEARCH…BootLoad… DOWNLOAD process with the Cortex Microcontroller.


Tethering Controller and Joystick

Do this in 2014

After updating the firmware on both the joystick and Cortex microcontroller:

  • Connect the two devices with the tethering cable and turn them both on.

  • Wait until both VEXNet LEDs turn solid green.

    This lets the devices learn each other’s addresses, so that they can talk together wirelessly.


BEST Control System

  • From BEST Robotics, Inc. online Resources

  • Includes photos of all items in Returnable Kit

    • Hookups, labels, system features of Cortex

    • Motor connections & motors, servos

    • Digital, analog connections

    • BEST default firmware (default program)

    • Programming options

    • Testing tips; team tips; joystick calibration
