2AI - AI_on_demand_once.py with synchronous mode.
3
4This example demonstrates the process of obtaining AI data in on demand mode.
5Additionally, it retrieve AI data from WifiDAQF4A.
6
7To begin with, it demonstrates the steps to open the AI and configure the AI parameters.
8Next, it outlines the procedure for reading the AI on demand data.
9Finally, it concludes by explaining how to close the AI.
