Analog Input

Non-Trigger Non-double-buffered Asynchronous

Continuous Analog Input

This section describes the function flow typical of non-trigger, non-

double-buffered asynchronous analog input operation. While per-

forming continuous AI operation, the AI configuration function has

to be called at the beginning of your application. In addition, for

asynchronous AI, the SyncMode argument in continuous AI func-

tions has to be set to ASYNCH_OP.

AI_ContReadChannel/

AI_ContReadChannelToFile
