Verifying the IP address in SmartDashboard
Using OutlineViewer to verify that the program is working
You can verify that the robot program is generating SmartDashboard values by using the OutlineViewer program. This is a java program, OutlineViewer.jar that is located in the USERHOME\wpilib\tools folder. It is run with the command: java -jar OutlineViewer-with-dependencies.jar. In the host box, enter your roboRIO hostname (roboRIO-####.local where #### is your team number with no leading zeroes). Then click "Start Client"
Look at the second row in the table, the value "SmartDashboard/Counter" is the variable written to the SmartDashboard via NetworkTables. As the program runs you should see the value increasing (41.0 in this case). If you don't see this variable in the OutlineViewer then you should look for something wrong with the robot program or the network configuration.
