Class HardwareTimer

java.lang.Object

edu.wpi.first.wpilibj.internal.HardwareTimer

All Implemented Interfaces:

Timer.StaticInterface

public class HardwareTimer
extends java.lang.Object
implements Timer.StaticInterface

Timer objects measure accumulated time in milliseconds. The timer object functions like a stopwatch. It can be started, stopped, and cleared. When the timer is running its value counts up in milliseconds. When stopped, the timer holds the current value. The implementation simply records the time when started and subtracts the current time whenever the value is requested.

Method Detail

delay

public void delay(double seconds)

Pause the thread for a specified time. Pause the execution of the thread for a specified period of time given in seconds. Motors will continue to run at their last assigned values, and sensors will continue to update. Only the task containing the wait will pause until the wait time is expired.

Specified by:

delay in interface Timer.StaticInterface

Parameters:

seconds - Length of time to pause

getFPGATimestamp

public double getFPGATimestamp()

Return the system clock time in seconds. Return the time from the FPGA hardware clock in seconds since the FPGA started.

Specified by:

getFPGATimestamp in interface Timer.StaticInterface

Returns:

Robot running time in seconds.
