The joystick close VI's error out is not wired to the flat sequence around stop because it is not essential. As before, use use an Open VI to get a reference to the joystick, call the Get Values VI repeatedly, and finally use the Close VI when the loop is done. Now we introduce a joystick to this example. Even though it doesn't do anything with the Close VI's error out, it still requires that data before being able to Stop. Because the flat sequence has a tunnel for the loop boolean and the Close VI's error out, it will not run until the loop ends and Close finishes.

This is why the VI to begin communication with the Driver Station runs right as the example VI begins, because it doesn't require any inputs. A VI will only run once all of its inputs have been satisfied.
LabVIEW is a dataflow-based programming environment. However, we want to make sure we close the SD540C reference before the VI stops. As you may expect, the Stop block will stop this VI.
The structure that looks like a film strip around the stop sign is flat structure sequence. The loop reads the value of the speed slider and uses it as the input to the Set VI. The CAN ID and a slider for the Speed are on the front panel. We also start communication with the driver station, but only once (outside of the loop). There is a twenty-millisecond delay in the loop so we don't bombard the roboRIO with data. We open a reference, repeatedly set its speed, and close the reference once the stop button is pressed. This is the most basic set of blocks to make an SD540C move. Examples that use joystick input, such as SD540C Joystick.vi, will not work correctly under autonomous mode (joystick input will be blocked).
#HOW TO INSTALL FRC DRIVER STATION CODE#
Even though we are running a single VI as an example and don't have separate code for each mode, it is still required for safety. Keep in mind that the Driver Station must have Teleoperated, Autonomous, or Test mode enabled to allow an SD540C to run. You can right-click "Target (roboRIO-#-FRC.local)" and select Disconnect on the other project. You may see a warning if you already have Java or C++ code running on your roboRIO. If another LabVIEW project is currently open and connected to the roboRIO, a second project will not be able to connect at the same time. If it fails to connect please check your team number is set correctly and the roboRIO has an active connection to the computer running LabVIEW. It may take a minute to connect to the roboRIO and copy over all the VIs. To execute a VI, click the white arrow on the left of the toolbar (on the front panel or block diagram), or use Ctrl+R, or Operate -> Run, right-click the VI in the Project Explorer and select Run. Here you can see the "code" that makes the VI run. Hit Ctrl+E to open the block diagram (or use Window -> Show Block Diagram). There is where you can interact with the VI.
#HOW TO INSTALL FRC DRIVER STATION UPDATE#
In the "IP Address / DNS Name" field, update the text box with your team number.ĭouble-click a VI in the Project Explorer to open it up. Further examples may assume basic knowledge from the previous examples, so we suggest you go in order.īe sure to change your team number! Right-click "Target (roboRIO-540-FRC.local)" and select Properties. Below you can find a description of each example VI. Here is a project containing eight examples, four each for the SD540C and CANLight. Go ahead and open up LabVIEW! Or, if you already have it open and just added the mindsensors VIs, restart LabVIEW. You will not be able to use the mindsensors VIs in LabVIEW if the mindsensors FRC library is not on your roboRIO.
You must successfully run this tool at least once to get the mindsensors FRC library on your roboRIO.

Read more on how to download and use this tool on our blog post. The mindsensors Configuration Tool will also allow you to update firmware. For the CANLight it also features a live-updating color test mode. For the SD540C this includes changing the ID, name, limit switch settings, invertedness, and stop behavior. The mindsensors Configuration Tool can be used to change the parameters of your SD540C and CANLight devices. In mindsensors_LabVIEW.zip you will find a folder similarly named ThirdParty.
Navigate to the following folder, or the equivalent if you have installed LabVIEW elsewhere: C:/Program Files (x86)/National Instruments/LabVIEW 2016/vi.lib/Rock Robotics/WPI/ThirdParty.
#HOW TO INSTALL FRC DRIVER STATION ZIP#
zip archive, it contains the new VIs for your LabVIEW environment. You will need to download the mindsensors FRC library for LabVIEW. Make sure you have the latest FRC LabVIEW updates and the 2017 image on your roboRIO before continuing. Getting Started with the 2017 Control System is a great place to start. WPILib has some fantastic documentation on setting up your roboRIO and development environment. This blog post will guide you through programming your CANLight and SD540C devices from LabVIEW.
