2AO - AO_write_one_channel.py with asynchronous mode.
3
4This example demonstrates the process of writing AO signal of EthanO.
5To begin with, it demonstrates the steps to open AO.
6Next, it outlines the procedure for writing digital signals with channel to the AO pins.
7Finally, it concludes by explaining how to close AO.
