_tkinter.TclError: no display name and no $DISPLAY environment variable
* Port ttyS0 is not connected to a Petoi device!
I have verified that the switch on the back of the Nyboard is set to Rpi, and I have verified good continuity between the connections on the back of the Pi to the back of the Nyboard. None of the pins are shorted. I have also verified that I can control the GPIO pins on the Pi with a simple LED control python script with a breadboard.I can run the ardSerial.py and example.py if I set the Nyboard to Arduino and connect the Pi and Nyboard through micro usb. Does anyone have experience with this issue?
