Package edu.wpi.first.wpilibj

Class TimedRobot

java.lang.Object

edu.wpi.first.wpilibj.RobotBase

edu.wpi.first.wpilibj.IterativeRobotBase

edu.wpi.first.wpilibj.TimedRobot

All Implemented Interfaces:

AutoCloseable

Direct Known Subclasses:

TimesliceRobot

public class TimedRobot
extends IterativeRobotBase

TimedRobot implements the IterativeRobotBase robot program framework.

The TimedRobot class is intended to be subclassed by a user creating a robot program.

periodic() functions from the base class are called on an interval by a Notifier instance.

Constructor Details

TimedRobot

protected TimedRobot()

Constructor for TimedRobot.

TimedRobot

protected TimedRobot(double period)

Constructor for TimedRobot.

Parameters:

period - Period in seconds.

Method Details

close

public void close()

Specified by:

close in interface AutoCloseable

Overrides:

close in class RobotBase

startCompetition

public void startCompetition()

Provide an alternate "main loop" via startCompetition().

Specified by:

startCompetition in class IterativeRobotBase

endCompetition

public void endCompetition()

Ends the main loop in startCompetition().

Specified by:

endCompetition in class RobotBase

addPeriodic

public final void addPeriodic(Runnable callback, double periodSeconds)

Add a callback to run at a specific period.

This is scheduled on TimedRobot's Notifier, so TimedRobot and the callback run synchronously. Interactions between them are thread-safe.

Parameters:

callback - The callback to run.

periodSeconds - The period at which to run the callback in seconds.

addPeriodic

public final void addPeriodic(Runnable callback, double periodSeconds, double offsetSeconds)

Add a callback to run at a specific period with a starting time offset.

This is scheduled on TimedRobot's Notifier, so TimedRobot and the callback run synchronously. Interactions between them are thread-safe.

Parameters:

callback - The callback to run.

periodSeconds - The period at which to run the callback in seconds.

offsetSeconds - The offset from the common starting time in seconds. This is useful for scheduling a callback in a different timeslot relative to TimedRobot.
