Problem With Competition Template

VEX V5 Technical Support
1

Hello,

I wrote a simple program that works fine when I download and compile it. However, when I paste the exact program code into a competition template and compile & download the template, the robot doesn’t do anything other than make a slight motor noise.

I’ll paste the code to both the program file and the template file. Any help would be greatly appreciated.

Thanks!

Program Code (Works fine when compiled and downloaded):

#pragma config(Sensor, dgtl1, leftEncoder, sensorQuadEncoder)
#pragma config(Sensor, dgtl3, rightEncoder, sensorQuadEncoder)
#pragma config(Motor, port3, rightMotor, tmotorVex393, openLoop)
#pragma config(Motor, port10, leftMotor, tmotorVex393, openLoop, reversed)
//!!Code automatically generated by ‘ROBOTC’ configuration wizard !!//

task main()

{
/Reset encoders to 0/
SensorValue [leftEncoder]=0;
SensorValue [rightEncoder]=0;

while (SensorValue [rightEncoder]<200)
{
motor[leftMotor]=127;
motor[rightMotor]=127;
wait1Msec(2000);
}
motor[leftMotor]=0;
motor[rightMotor]=0;
wait1Msec(1000);

/Reset encoders to 0/
SensorValue [leftEncoder]=0;
SensorValue [rightEncoder]=0;

while (SensorValue [leftEncoder]<200)
{
motor[leftMotor]=127;
motor[rightMotor]=-127;
wait1Msec(2000);
}

}

Template Code (Doesn’t work when compiled and downloaded):

By " Not work", do you mean the autonomous portion or the user portion. To test out your autonomous, you need a competition switch. The rest of this post is about if it’s user control that’s not working. Seeing as though your code compiled and downloaded without errors and your code looks fine to me, I would suggest that maybe your Cortex is messed up in some way. If not, then check the wiring. If all those fail, then there may be something on your robot restricting movement from the axle.

Side note: Why is your left motor plugged into port 10 and your right in port 3? It doesn’t mess anything up, but whyyyy.

For your autonomous code to work, you need to have a competition switch, which can be purchased here: VEXnet Competition Switch - VEX Robotics

Alternatively, if you have a wireless programming kit (available to purchase here: http://www.vexrobotics.com/vexedr/products/accessories/electronics/276-2186.html )

If you use the wireless programming kit, then you should connect it correctly then go to Robot >> Advanced Tools >> VEXNet Joystick Viewer on your RobotC software. This has a built-in competition switch

I was originally in motor ports 1 and 10 as per the stock Claw Bot setup. The motor stopped working in Port 1, so I moved to Port 3. I only brought home one adapter, so I had to leave the other motor in Port 10.

Thanks!

does this need to be included?

#pragma platform(VEX)

//Competition Control and Duration Settings
#pragma competitionControl(Competition)
#pragma autonomousDuration(20)
#pragma userControlDuration(120)

#include "Vex_Competition_Includes.c"   //Main competition background code...do not modify!
