Tips for C++ programming the 2010 control system

[woodk]

I think the classmate sets itself to 10.xx.yy.5 when you go into the Driver Station account. You should probably leave it that when even if you are using for development.

If you use a separate laptop for development, you can set it to 10.xx.yy.6

Make sure your dashboard is actually updated as per my previous message (right before yours). You should see a compass type angle readout in the bottom-right corner. If you don't have this then your Dashboard is not updated properly and you will have to uninstall it and then reinstall it using DSUpdate1.0for2010.zip

Under
C:\WindRiver\vxworks-6.3\target\h\WPIlib
I have a Vision and a Vision2009 folder
Should only Vision2009 be used this year?

The Vision dir is modern and what youd should use. The Vision2009 is the code from last year and is obsolete. Only there for old program compatibility.

The classmate can always be 10.xx.yy.5

The calls to DashboardDataSender are still there as per the 2010 Image demo.

You are running it locally? Are you getting an error from the data unpacking on the dashboard? Perhaps your data types don't match.

Correct.

Last year, laptops attached to the dashboard would have the IP of 10.xx.yy.6, while the dashboard it self had 10.xx.yy.5. This year, because the dashboard and laptop are one item, the code needs to send its data to 10.xx.yy.5. Just wait until the new versions of the examples ship out and the updated verison of the CameraToDashboardExample sends to the correct IP.

The robot is the server and the dashboard is the client. Therefore the IP address of the dashboard does not matter. It will connect to the robot to get images.

I notice that the driverstation program changes your IP address to 10.xx.yy.5 however the CameraToDashboardExample program says it is sending the images to 10.xx.yy.6 I tried setting up a remote dashboard with the IP10.xx.yy.6 but it is not able to connect to the robot at all.

Remote dashboard is only used if you are running the dashboard on a different laptop than the driver station application. If you choose local, the packets will be sent to localhost.

There is source code available. What source are you waiting for? Look at http://firstforge.wpi.edu/sf/projects/wpilib

Yes, it is now. It was not when I posted.

The problem I had was that DSUpdate1.0for2010 did not in fact update the dashboard. It updated the driver station (the bottom window) but not the dashboard. I had to uninstall the old dashboard then reinstall the update for it to work. From several comments I have seen, I think many people have had this problem but not recognized it. Once the dashboard update installed properly the camera images appeared fine. The key thing to look for is if you have the gyro compass in the bottom-right corner of the dashboard. If you do not have this, then your update was not successful; you are still using the old version of the dashboard and you will not receive video.
