This is so the warning about 'restricted' api's & javafx don't show up in Eclipse.Go get coffee, the install takes about 10 minutes. Select e(fx)clipse - IDE, then Next/Next/SignLifeAway/Finish.In the "Work With" drop-down, select 'All available sites'.Thus it is far superior to the command prompt for platform-independent code development in Windows. This terminal is also a 'Linux-lite' terminal - many standard unix commands work. If you want help from your mentors in getting out of a mess with Git, they'll need this tool. Go to and install the Git Bash terminal.Go to and install the latest "Eclipse for Java Developers".On Windows, search the start menu for 'Java update'. Java usually installs an update executable. If you have an older version of JDK 8, you should update it.If you have JDK 6 or 7 installed, should you uninstall it first.Install the Java JDK 8, update 151 or greater.If you don't feel comfortable making one, ask around - someone already has this installer. NOTE - you will need to create an NI account.This installs the mDNS handler needed for the computer to communicate with the RoboRIO.Install the latest FRC Update Suite from here.When testing a robot during a 'live' match in the classroom, we should set those parameters up. The WPILIB screensteps describe how to setup our wireless bridge to be similar to the QoS and bandwidth limitations live on a field.As soon as possible post-match, get the data to our (TBD) Google Sheet for analysis by the pit crew.Codex data should be stored in a CSV format with a.Storing data to a file may happen either on the RIO (to a mounted USB drive) or to the driver's station. High-frequency data from the robot to the driver's station, such as our sensor and joystick data, should use the Codex protocols over UDP.For easy JSON conversion, use Google's GSON library.If NetworkTables does not support JSON, or it has a critical flaw with JSON, it is somewhat easy to use the Codex IO code to create a custom String data sender.Single-use or low rate data may be in JSON format, and is sent via NetworkTables (assumes v4.0 still includes JSON support).NetworkTables had some issues with stale cache data in the past, but v4.0 may have addressed this.Since 2015, the NetworkTables protocol has been the only network comms that have worked 99% of the time (albeit a bit bandwidth-heavy).Generally this is most custom data from the driver's station to the robot. Critical configuration data will use NetworkTables.That way we aren't constantly changing the enumerations so quickly. Hint: it probably is, but only AFTER we have a better understanding of the states we want to capture. Local state variables may be put into a Codex framework if you feel it is worth capturing.All Joystick inputs, sensory data, and outputs (including Talon, Pneumatic and custom outputs like LED's) will be managed via the Codex framework.Once we realize how we can apply neural nets, we will have a great set of training data if we've already collected it all! Therefore: The first step to applying neural nets to our robot is to collect data, even when we aren't using it directly.General Mantra for Data Structures & Network Communications If you disagree, then get this 'simple' version of vision working (from processing all the way through integration into robot code and driver inputs) early. Note that we will do vision processing on the RIO. VisionRIO/ - Our vision code start out being specific to how the RoboRIO will process images and distill them to targeting info. It may incorporate Shuffleboard at some point. It depends on the common and visionRIO projects.ĭisplay/ - Our configuration and output display lives here. * backwards while the gyro is used for direction keeping.Common/ - This contains all of the types used in communications, on the display(s), in vision, and on the robot. This program uses a joystick to drive forwards and * This is a sample program to demonstrate how to use a gyro sensor to make a * must be accompanied by the FIRST BSD license file in the root directory of */ * Open Source Software - may be modified and shared by FRC teams. When you open the example, it should look like this. To show you how you would use the gyro in your code, we'll take a look at the gyro example that comes packaged in the WPI library and modify it to use the ADXRS450 gyro instead of the analog gyro.
