WPILib 2022.1.1 Beta 3 Release Pre-release
Pre-release

Getting Started

This is the third beta release of WPILib for the 2022 season. This requires the 2022 v2.x roboRIO image (either roboRIO 1 or roboRIO 2).

Check out what's new for 2022 and jump directly to the WPILib installation guide.

A list of known issues with this release can be found here and in Beta 3, the following are broken:
TBD

Major changes from Beta 2:

  • Glass, SysId, and Simulation GUI now use multi-file JSON save formats instead of INI and have support for loading/saving the workspace; when started from the vscode tool menu, these default to using the project directory for saving rather than the system-global location
  • Glass and sysid now install desktop shortcuts
  • Desktop shortcuts for tools now have the year in the name
  • Fixed on-robot debugging
  • Fixed simulateJava on Mac
  • Fixed Java Romi build
  • roboRIO JDK artifact is again included in the installer
  • Rev Pneumatics Hub enhancements (compressor config mode, faults)
  • Added new Counter implementations

If you're starting from a 2021 robot project, you will need to import it to create a 2022 project. The import process is particularly important for 2022, as it will try to make a number of automated corrections for the various breaking package moves that happened in 2022.

Getting Started

This is the second beta release of WPILib for the 2022 season. This requires the 2022 v2.x roboRIO image (either roboRIO 1 or roboRIO 2).

Check out what's new for 2022 and jump directly to the WPILib installation guide.

A list of known issues with this release can be found here and in Beta 2, the following are broken:

This release has breaking changes to the robot template from beta 1. It will be necessary to either re-import your project from 2021 or create a new robot project and copy your beta 1 code into it.

Major changes from Beta 1:

  • Fixed RoboRIO 2 deployment version checking; requires roboRIO image v2.3 (workaround still required for v2.2)
  • Added back deployment error messages (RoboRIO not found)
  • Fixed Romi support
  • Fixed Java simulation without Visual Studio installed
  • Fixed deployment of src/main/deploy
  • Gradle updated to 7.2
  • Visual Studio Code has been updated to 1.62.0
  • Fixed Linux desktop icon permissions
  • Fix "chcp not found" warning message seen when running simulation on Windows
  • Shuffleboard: camera server streams not appearing issue from 2021 has been fixed

If you're starting from a 2021 robot project, you will need to import it to create a 2022 project. The import process is particularly important for 2022, as it will try to make a number of automated corrections for the various breaking package moves that happened in 2022.

WPILib 2022.1.1 Alpha 2 Prerelease Pre-release
Pre-release

Alpha release for use by vendors only.

  • Requires 2022 image (v2.x)

Errata

  • /usr/local/frc/bin/frcRunRobot.sh must be edited on the 2022 Rio image (see below) for programs to run
  • Need internet connectivity on initial build (Maven artifacts currently missing from installer)
  • Simulation launching doesn't work
  • C++ tools don't work

frcRunRobot.sh fix

The last 3 lines of /usr/local/frc/bin/frcRunRobot.sh are:

/sbin/start-stop-daemon --start \
   --pidfile /var/run/natinst/FRC_UserProgram.pid \
   --make-pidfile --exec /bin/bash -- \
   -l -c "exec $PROG $ARGS 2>&1 | FRC_ConsoleTee | tee /var/local/natinst/log/FRC_UserProgram.log"

The last line must be edited (as admin) to remove "exec", resulting in:

   -l -c "$PROG $ARGS 2>&1 | FRC_ConsoleTee | tee /var/local/natinst/log/FRC_UserProgram.log"
