Post Downloading to VEX EDR Cortex Microcontroller
Hi,

I am currently starting up my VEX EDR Cortex for the first time. I am using ROBOTC for VEX Robotics Version 4.30 on an HP EliteBook 8570W. The license I am using is through our county school system (Queen Anne's County Public Schools) for our GTT PLTW program.

I have used the "Download a ROBOTC Sample Program [PDF]" from the RobotC support page to help download and execute a sample program (VEX2, Basic Movement, Moving Forward) from my computer to the cortex. Couple of issues:

1) Even though everything seems to be working from the ROBOTC/PC perspective, the program is not running on the cortex
2) Whether the cortex is hooked up via USB to the computer and Robot C or NOT, the motors (2-wire Motor 393) begin continuously running as soon as they are plugged into Motor Ports 2 and 3 of the cortex.

How can I trouble shoot this...I have done Automatic Firmware updates as well as manual updates for RobotC Firmware as well as the Masture CPU update...I have completed the motor and sensor setup according to the support information on the RobotC website...nothing seems to work. HELP!

Thanx

To use a VEX 2 wire 393 motor in ports 2-9 you need a motor controller 29. If you are only running 2 motors try ports 1 and 10 or use the 2 wire to 3 wire boxes to convert input signal to motor voltage.

Thanx...I was wondering if the 2-wire versus 3-wire motors would make a difference. I will try : )
