I tried the Neo.GPIO library from https://github.com/smerkousdavid/Neo.GPIO Works very well. I could see the readings from the on-board sensors on the terminal. I would now like to view this data as a scrolling graph. Since I am a complete novice when it comes to Linux and Python, I do not know any way of doing this. If I could send this data out through the microUSB port on Neo and receive it on PC, then I can do the plotting on the PC. Can some one give me a hint? Thanks
