DO write pins

 1'''
 2DIO - DO_write_pins.py with asynchronous mode.
 3
 4This example illustrates the process of writing a high or low signal to a DO pin from USBDAQF1CD.
 5
 6To begin with, it demonstrates the steps required to open the DO pin.
 7Next, voltage output is written to the DO pin.
 8Lastly, it concludes by closing the DO pin.
