Hi friends! I’d like to share the program I developed to make cool graphs with serial port input that can be connected either to wixel or to arduino also.
You can this way understand better the debug of your program because you can graph any variable you are using 
good luck! I haven’t yet made a standalone executable for windows but you can execute it with python-pygame interpreter and pyserial library (ask me how to install them it if you are not sure). In the future there will be a standalone executable
