Code problems, I think.
 

The code deploys without error but when I take the joystick to all forward or backwords (1, -1) or full left or right, the motors stop working alltogether. If i slowly ramp up to full left, right, forward, or backwards though it works fine. I think this is a code problems so any help is much appreciated.

How are your Jags set?

Re: Code problems, I think.
 

Sorry, I don't know what you mean. In the code I have opened 4 motors on jags. All the jumpers on the jags seem to be right. The wheels only stop now when i go about half power left, i can go full in all other directions.

Re: Code problems, I think.
 

Oh, sorry. I meant to ask whether they are set to stop or coast.

Are you using any watchdog or wait delays in TeleOp?

Re: Code problems, I think.
 

The jags are set to coast, no delays in the program. When the wheels stop working the jags get a slow yellow flash( think that means no servo connection.)

Re: Code problems, I think.
 

So i have worked it down to this problem, when i have all 4 motors at full forward, the crio stops suppling power to the digital sidecar( the 5v light turns off). If i then toggle the enable, disable on the drivers station the digital sidecar turns on and then stops when at full power. We used a new battery and changed the side car.

Our team had the same problem. Is the game adapter hooked up to the 12v spot on the pwer distribution board?

Re: Code problems, I think.
 

The game adapter is hooked up correctly, but we had it connected through the ethernet cable to the crio (Before it's asked, yes it was in port 1). I have tried multiple different codes, tank/arcade 4 wheel have the problem, even when i tried using 2 two wheel arcade drives the same problem occurred. I am starting to think this is a electrical problem not code so I might post it there.

Re: Code problems, I think.
 

So the plot thickens, we have just found out that if you unplug any 2 pwm cables (that are connected to jags) the motors are able to go full power and the digital side car doesn't lose the 5v signal from the crio.

Re: Code problems, I think.
 

Disconnect all the cables from your digital sidecar, including the 37 pin cable, but keep the power cable plugged in. When you do this, do all 3 power LEDs shine brightly? If not, you have a problem with the power cable.

I'm a little concerned when you say the digital sidecar looses it's 5v signal from the cRIO. Can you show some pictures of how its wired?

Re: Code problems, I think.
 

No, all 3 lights don't show up.

Re: Code problems, I think.
 

That's conclusive. You need to correct the 12v power input to the Digital Sidecar. It should come from a 20A circuit breaker on the Power Distribution board. Make sure the wires are stripped the proper length so that the Wago connectors (red/black and white) bite down on the bare wire.

Re: Code problems, I think.
 

Yepp that was the problem, we had the wires reversed.
Thanks very much for all the help.
