Constructor Detail

InterruptableSensorBase

public InterruptableSensorBase()

Create a new InterrupatableSensorBase

Method Detail

allocateInterrupts

public void allocateInterrupts(boolean watcher)

Allocate the interrupt

Parameters:

watcher -

cancelInterrupts

public void cancelInterrupts()

Cancel interrupts on this device. This deallocates all the chipobject structures and disables any interrupts.

waitForInterrupt

public void waitForInterrupt(double timeout)

In synchronous mode, wait for the defined interrupt to occur.

Parameters:

timeout - Timeout in seconds

enableInterrupts

public void enableInterrupts()

Enable interrupts to occur on this input. Interrupts are disabled when the RequestInterrupt call is made. This gives time to do the setup of the other options before starting to field interrupts.

disableInterrupts

public void disableInterrupts()

Disable Interrupts without without deallocating structures.

readInterruptTimestamp

public double readInterruptTimestamp()

Return the timestamp for the interrupt that occurred most recently. This is in the same time domain as getClock().

Returns:

Timestamp in seconds since boot.
