Asynchronous Digital Input Monitoring Functions

DI_AsyncCheck
Check the current status of the asynchronous digital input operation

DI_AsyncClear
Stop 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
