WPILib 2020.3.2 Release

Getting Started

Download the appropriate file for your platform and see the installation instructions at Getting started.

For this release, it's okay to skip reinstalling Visual Studio Code, JDK, and the compiler if you already installed them with a previous release.

After you install the update, VS Code will prompt you when opening an older 2020 project whether or not you want to upgrade it to 2020.3.2.

What's Changed In This Release (since 2020.2.2)

WPILib

Java

  • TrapezoidProfile: Fixed aliasing of m_initial to result in calculate() (#2284)
  • Added more detail to RuntimeLoader failure message (#2309)
  • Fixed null check order in SendableRegistry (#2314)
  • Added methods for getting the color of an AddressableLED (#2366)

C++

  • Removed "Set Camera Server Shared" message (#2285)
  • Added missing include to ShuffleboardEventImportance.h (#2310)
  • Added support to circular_buffer for types that are not implicitly convertible from int (#2350)
  • Fixed two cases in circular_buffer where a reference was being returned to a constant (#2350)
  • Made units of TrapezoidProfile public (#2342)

C++ and Java

  • Don't create a duplicated state at knot points when generating trajectories using quintic splines (#2307)
  • Added setEnabled method to RamseteController (#2313)
  • Added hasElapsed and advanceIfElapsed functions to Timer class. We encourage teams to consider using these functions instead of hasPeriodPassed, which has the confusing behavior of resetting the timer--advanceIfElapsed has the same functionality as hasPeriodPassed. If you want to only check that the time period has elapsed, use hasElapsed instead (#2322)
  • Fixed DifferentialDriveVoltageConstraint for tight turns with zero velocity (#2341)
  • Fixed notifier race that could happen with very fast notifiers (#2370)
  • Added a method for releasing a waiting interrupt (#2347)
  • Added a way to access NetComm's SendConsoleLine function (#2337)

New Command Framework

  • [C++] Fixed POVButton (#2294)
  • [C++] Fixed ParallelRaceGroup multiple calls behavior--the Java version was correct, but the C++ version would only run once (#2339)

Documentation

  • Added new speed controllers to shuffleboard docs and fix a few bad links/typos (#2288)
  • Fixed DriveSubsystem.getHeading() javadoc (#2282)
  • Added missing references to "f" in PIDSubsystem javadoc (#2318)
  • Added note that only a single instance of ADXRS450 is supported (#2349)

Simulation

  • Added support for naming I/O in the GUI. Nearly any name in the GUI (e.g. "PWM[0]") can be renamed by right clicking on it and changing the name (#2292)
  • Added 2D field view to the GUI. The field image and robot image can be loaded or just a wireframe used. The robot can be moved and rotated with a mouse click + drag. The robot position is settable in robot code via the Field2d class (#2261)
  • Changed Filesystem.getDeployDirectory() to src/main/deploy in simulation (#2293)
  • Fixed ADXL345 and ADXL362 simulation Y value (#2332)
  • Added SimulationInit and SimulationPeriodic functions. These can be used as an easy way to add code that runs only in simulation (#2377)

Examples

  • Fixed GearsBot log methods not being called periodically (#2280)
  • Fixed RamseteCommand RobotDrive watchdog (#2298)
  • Added feed-forward and slew rate limiting to advanced drive examples (#2301)
  • Examples which use SendableChooser now set a default option (#2361)

Templates

  • Added missing methods to Timed and TimedSkeleton (#2306)

PathWeaver

  • PathWeaver paths that used different units than meters would cause issues with WPILib trajectory following. For new projects, PathWeaver now defaults to converting to meters in the exported file, regardless of the units used in the project. For backwards compatibility, projects created with earlier versions will default to exporting in project units, but a warning is displayed recommending the setting be changed (wpilibsuite/PathWeaver#180)

WPILib 2019.4.1 Update

Getting Started

Download the appropriate file for your platform and see the installation instructions here: https://wpilib.screenstepslive.com/s/currentCS/m/getting_started/l/999999-installing-c-and-java-development-tools-for-frc

For this update, it's okay to skip reinstalling vscode, JDK, and the compiler if you already installed them with 2019.1.1, 2019.2.1 or 2019.3.2.

After you install the update, vscode will prompt you when opening an older project whether or not you want to upgrade it to 2019.4.1.

Installing Visual Studio Code

Visual Studio Code (vscode) is the recommended and supported IDE. However, it requires a separate download as part of the install process. Make sure to click the "Select/Download" button during the install process if you want to install vscode.

If you need to install vscode on an offline machine, run the installer first on an Internet-connected machine and click the "Select/Download vscode" button. Then copy both the installer and the downloaded OfflineVsCodeFiles zip file to the offline machine.

What's Changed In This Release (since 2019.3.2)

WPILib

  • [HAL] Fix not being able to use SPI CS1 as an interrupt (#1614)
    This fixes an issue with ADIS16470 not working properly.
