You could also use a USB2TTL8. Sending an 8 bit digital output is pretty easy to do: import serial #Open connection to USB2TTL8 USB serial s = serial.Serial('/dev/cu.usbmodem1234567', baudrate=128000, timeout=0.01) # Toggle TTL output to 255 for 5000 usec and then goto 0 s.write(b'WRITE 255 5000 0\n') # or another example.... # Set digital output to 64 while stimulus is being drawn # and to 128 while flip() is blocking s.write(b'WRITE 64\n') # draw stim my_stim.draw() s.write(b'WRITE 128\…
