4.5.4 Asynchronous Digital Input Monitoring Functions
DI_AsyncCheck Checks the current status of
the asynchronous digital input
operation.
DI_AsyncClear Stops the asynchronous
digital input operation.
DI_AsyncDblBufferMode Enables or Disables double
buffer data acquisition mode.
DI_AsyncDblBufferHalfReady Checks whether the next half
buffer of data in circular buffer
is ready for transfer during an
asynchronous double-
buffered digital input
operation.
DI_AsyncDblBufferTransfer 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_AsyncMultiBufferNextReady
Checks whether the next
buffer of data in circular buffer
is ready for transfer during an
asynchronous multi-buffered
digital input operation.
