Syntax

public class PRUEventHandler

Provides the storage and handling of the various items associated with a PRU Event.

Public Constructors

public PRUEventHandler(PRUEventEnum pruEventIn, PRUDriver pruDriverIn)

Constructor.

Parameters: pruEventIn - The event we represent.; pruDriverIn - The PRUDriver object which created this event data object.

Public Methods

public void StartPRUEventMonitor()

Starts the interrupt event thread for a PRU event. There is one thread per interrupt event.

Basically what is happening here is that we are starting a separate thread which will immediately try to read the UIO file and will block on it until an event happens. Once the event happens, a user specified handler is called to process the interrupt data and clear the interrupt.

public void StopPRUEventMonitor()

Stops the pru event monitor thread. Since the worker thread immediately enters into a blocking read we just hard kill the thread.

public UInt32 WaitForEvent()

Waits for the specified event. Will stall with a blocking read until the event is triggered.

Returns: the total number of events processed by the uio file (from any source) since boot up.

Public Properties

public int EventFD { get;set }

Gets/sets the PRU event file descriptor. THis is the file descriptor of the open UIO file.

public int InterruptEventsReceived { get;set }

Gets/Sets the count of events received.

value: count of events received.

public int InterruptEventsSent { get;set }

Gets/Sets the count of events sent.

value: count of events sent.

public PRUEventEnum PRUEvent { get }

Gets the PRU event. There is no set accessor - this value is fixed when this object is created.

value: The PRU event.

public PRUDriver PRUEventDriver { get }

gets the PRUDriver that created this PRU event. There is no set accessor - this value is fixed when this object is created.

value: The PRUDriver object.
