19. *
20. * Example Category:
21. *    AI
22. *
23. * Description:
24. *    This example demonstrates how to use Instant AI function.
25. *
26. * Instructions for Running:
27. *    1. Set the 'deviceDescription' for opening the device.
28. *    2. Set the 'startChannel' as the first channel for scan analog samples
29. *    3. Set the 'channelCount' to decide how many sequential channels to scan analog samples.
30. *
31. * I/O Connections Overview:
32. *    Please refer to your hardware reference manual.
