2DIO - DO_write_pins.py with synchronous 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.
