12 ? PCIS-LVIEW NT/2000/98 Overview
4.4.4 Asynchronous Digital Input Monitoring VIs
DI Async Check: Checks the current status of the asynchronous digital input operation.
DI Async Clear: Stops the asynchronous digital input operation.
DI Async Double Buffer Mode: Enables or Disables double buffer data acquisition mode.
DI Async Double Buffer Half Ready: Checks whether the next half buffer of data in circular buffer is ready for
transfer during an asynchronous double-buffered digital input operation.
DI Async Double Buffer Transfer: Copies half of the data of circular buffer to user buffer. You can execute this
function repeatedly to return sequential half buffers of the data.
DI Async Multi Buffer Next Ready: Checks whether the next buffer of data in circular buffer is ready for
transfer during an asynchronous multi-buffered digital input operation.
