Re: yes comunication, yes code but no response by robot
 

We have swapped out the modules already and tested different cables and sidecars and tested the voltage on each sidecar and it is getting power but not a signal.

Re: yes comunication, yes code but no response by robot
 

When you say module you are referring to the Digital Sidecar correct?
If so, then the problem seems to be with your Crio. If you have a different digital module you should try swapping that in.

Re: yes comunication, yes code but no response by robot
 

Is the analog module properly installed with the jumper? If so, is the battery voltage showing on the classmate?

What happens if the Digital module is moved to the other slot (slot 6 I think) and your code is updated to output to that slot?

Re: yes comunication, yes code but no response by robot
 

Did you try a different cRIO?

Look closely at the DB15 connector for Slot 4. Make sure none of the pins are broken or bent. Use a good strong light to check for debris between the pins.



You're still being a bit vague in your descriptions of what you did. How have you "tested the voltage on each sidecar"? Which points did you measure? What do you see that indicates to you that it's not getting a signal?

Re: yes comunication, yes code but no response by robot
 

We do not have a different CRIO but i re imaged it and now when i try to upload code to the CRIO i get the error from windriver saying that It failed to launch to target server and that it could possilbly be caused by back end not connected and idk how to read this or what it means.

Re: yes comunication, yes code but no response by robot
 

As Alan Anderson has said multiple times, if you could provide more information on WHAT you have done, we would be able to help you more.

The error you received is because Wind River was unable to connect to the robot. This could be because the I.P. address of your computer is incorrect or you weren't connected to the robot properly elsewhere.

Did you input your team number correctly in the imaging tool?
Did you select the correct language?

Re: yes comunication, yes code but no response by robot
 

I did both of those things correctly and i was able to reimage it into java and download code to the robot like that through netbeans but not through windriver. The laptops ip was dynamic so it should not have been that. any other suggestions?

Re: yes comunication, yes code but no response by robot
 

It could definitely have been that!

What is assigning the IP address? How is the IP range determined? What address is the laptop actually ending up with?




Please, PLEASE try to understand that direct answers to some of the questions we're asking will be very useful to us. We're asking the questions in order to find out information that can help us help you. In many cases, you have answered a simple request not with the actual information or observation requested, but with your interpretation of what you think you observed. In others, you have simply failed to respond to the request. It's hard enough to troubleshoot something remotely when there is perfect communication between the remote "experts" and the person actually able to touch the system.

Re: yes comunication, yes code but no response by robot
 

BY the CRIO it is determined
we messed around with it but it was 10.13.18.6
i dont know what the IP range is

Re: yes comunication, yes code but no response by robot
 

The cRIO doesn't assign IP addresses.

You said that the laptop was using a dynamic IP address, which means there has to be a DHCP server somewhere on the network, most likely the router. Who configured it?

The phrase "messed around" gives no information on what you actually did.

Assuming your cRIO is at 10.13.18.2, the 10.13.18.6 address was correct for the computer you intend to use as a dashboard, and should not have been changed. Set the laptop to have a static IP address of 10.13.18.6 with a subnet mask of 255.255.255.0 and a default gateway address of 10.13.18.4 as specified in the control system manual.

Re: yes comunication, yes code but no response by robot
 

If you want to use the laptop as a replacement for the Classmate, and use it as the Driver Station, you need to set the IP to 10.13.18.5. Again only use 10.13.18.5 if this computer is going to be the DS.

If you could explain your entire setup it would be very useful to us in helping you.

Re: yes comunication, yes code but no response by robot
 

I dont want to do that but to download code to the robot we use a direct connection with an ethernet cable.

Re: yes comunication, yes code but no response by robot
 

i configured it just as you said above.
This however is not the problem anymore because we can download code to the CRIO now. We set one solenoid to true and set a motor to .5 and we know that the solenoid worked but the motor did not turn on. any suggestions?

Re: yes comunication, yes code but no response by robot
 

Then it's not going to be very easy for us to help.

Just the same suggestion I've been trying to give all along: give some more detail about what you're doing. For example, are you using a Victor or a Jaguar to control the motor? What does your code look like? What is the status LED on the speed controller doing? What is the speed controller wired to? What kind of motor are you trying to control? Is the Dashboard showing anything for the PWM output you are using?

Re: yes comunication, yes code but no response by robot
 

you misunderstood i meant i dont want to use it as the driver station.
The code is just s.set(true); with declarations.
and roller.set(.5); with declarations.
the led on the jaguar is flashing an orange light.
trying to control a cim motor.
I dont know how to check the driver station for the PWM output. how would i do that?
