AIO all channels loopback

  1'''
  2AIO - AIO_all_channels_loopback.py with asynchronous mode.
  3
  4This example demonstrates the process of AIO loopback across all channels of WifiDAQE3AOD.
  5It involves using AO pins to send signals and AI pins to receive signals on a single device, commonly referred to as "loopback".
  6The AI and AO pins are connected using a wire.
  7
  8Initially, the example demonstrates the steps required to open the AI and AO.
  9Next, it reads AI data and displays its corresponding values.
 10Following that, it writes digital signals to the AO pins and reads AI on-demand data once again.
 11Lastly, it closes the AO and AI ports.
