At the time beeing: manually. Sorry for that.
GPD-3303S uses a USB to serial converter chip provided by FTDI. If you have not installed its device driver, please download and install it on your machine first.
macOS and most Linux distributions support FTDI chips without installing a device driver.
>>> import gpd3303s
>>> gpd = gpd3303s.GPD3303S() # or .GPD2303S() or .GPD4303S()
>>> gpd.open('/dev/ttyUSB0') # Open the device
>>> gpd.setVoltage(1, 1.234) # Set the voltage of channel 1 to 1.234 (V)
>>> gpd.enableOutput(True) # Output ON
>>> v = gpd.getVoltageOutput(1) # read the actual voltage
