Detailed Descriptions of Programs
Trigger Mode Data I/O Through DMA Data Transfer or
Interrupt Operation
These programs tell you how to use PCIS-DASK to operate trigger
mode data I/O through DMA data transfer or interrupt operation.
Except for the additional input item postCount, the main screen of
these programs are similar with Single-Buffer Mode or Double-
Buffer Mode programs. Please refer to these two sections for the
details.
The postCount item represents the number of data accessed
after a specific trigger event or the counter value for deferring to
access data after a specific trigger event. Refer to the description
of AI configuration functions (AI_9111_Config, AI_9118_Config,
AI_9812_Config) for details.
NOTE Except for VB9812, all trigger mode data acquisition sam-
ple programs use external digital trigger source to provide
trigger signal. Refer to the card’s documentation if you
you want to operate for the detailed description of trigger
mode data acquisition.
