AI on demand in loop

  1'''
  2AI - AI_on_demand_in_loop.py with synchronous mode.
  3
  4This example demonstrates the process of obtaining AI data in on demand mode.
  5Additionally, it utilizes a loop to retrieve AI data with 5 times from STEM.
  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.
 10
 11If your product is "STEM", please invoke the function `Sys_setAIOMode`and `AI_enableCS`.
 12Example: AI_enableCS is {0, 2}
 13Subsequently, the returned value of AI_readOnDemand and AI_readStreaming will be displayed as follows.
 14data:
 15          CH0, CH1, CH2, CH3, CH4, CH5, CH6, CH7, CH0, CH1, CH2, CH3, CH4, CH5, CH6, CH7
