LoggableSmartDashboard

This library acts as a wrapper around the SmartDashboard class in WPILib, allowing for the logging of SmartDashboard values.

Installation:

Manual:

Add frclogtools.jar to a lib folder at the root folder of your repository.

With Gradle:

In build.gradle, add:

repositories {
    maven {
        url "https://jitpack.io"
    }
}

dependencies {
    implementation 'com.github.brokenfloppydisk:LoggableSmartDashboard:main-SNAPSHOT'
}

main-SNAPSHOT can be replaced with the commit hash for a specific version.

Then, run Build Robot Code or ./gradlew build.

Usage:

Use LoggableSmartDashboard.putNumber(), .putBoolean(), or .putString() in place of SmartDashboard to enable logging for these values.

Use LogManager.getInstance() to get an instance of the LogManager, and call .startLogging() and .stopLogging() to start and stop logging.

DataLog from WPILib is used to log values, so only WPILib 2022.4.1 and up is supported.

If no DataLog is passed to .startLogging(), the data will be written to the default log in DataLogManager.getLog() instead.

LogSmartDashboard is a command that automatically gets scheduled every 20 ms by LogManager to log the current SmartDashboard values.

To export the logs, use DataLog Tool (included in the installer for WPILib 2022.4.1)

The logs can also be processed with consolidate.py to consolidate the rows, as table exporting to CSV in DataLog Tool does not combine rows with the same timestamp.

Example Code:

Robot.java

import edu.wpi.first.util.WPIUtilJNI;
import edu.wpi.first.util.datalog.DataLog;
import edu.wpi.first.wpilibj.TimedRobot;
import edu.wpi.first.wpilibj2.command.CommandScheduler;
import frclogtools.lib.LogManager;
import frclogtools.lib.LoggableSmartDashboard;

public class Robot extends TimedRobot {
  private DataLog dataLog;

  @Override
  public void robotInit() {
    CommandScheduler.getInstance().cancelAll();
    dataLog = new DataLog();
  }

  @Override
  public void robotPeriodic() {
    CommandScheduler.getInstance().run();
  }

  @Override
  public void disabledInit() {
    LogManager.getInstance().stopLogging();
  }

  @Override
  public void disabledPeriodic() {}

  @Override
  public void autonomousInit() {}

  @Override
  public void autonomousPeriodic() {}

  @Override
  public void teleopInit() {
    LogManager.getInstance().startLogging(dataLog);
  }

  @Override
  public void teleopPeriodic() {
    long timestamp = WPIUtilJNI.now();
    LoggableSmartDashboard.putNumber("time", timestamp);
    LoggableSmartDashboard.putString("testString", "testString" + timestamp);
    LoggableSmartDashboard.putBoolean("testBoolean", timestamp % 2 == 0);
  }

  @Override
  public void testInit() {}

  @Override
  public void testPeriodic() {}
}
