I’m looking to create an API to control my [axidraw](https://axidraw.com/) through [WebUSB](https://developers.google.com/web/updates/2016/03/access-usb-devices-on-the-web) (currently only working on Chrome) with p5. The communication works by sending simple serial messages. My idea is to have the usual functions like `line` , `ellipse` etc. behave normally, but in a certain state draw with the drawing machine instead of to the canvas.

I know this might be out of the scope of the general codebase, but I was wondering what would be a good entry point into the API as I would like to publish it as an optional addon/extensions to p5. I have thought of creating function decorators to the existing library with a global switch to toggle using the Axidraw.

I think ideally it would function something like a custom renderer class, that doesn’t actually render anything on the screen. But again, I don’t know how that would work, since I don’t know if that would work with the paradigm since drawing with the physical machine would mean taking a significant time for each action.

Do you have any ideas on the subject?

@TiborUdvari : did you start some code on this subject ? I am planning on working with an axidraw soon I intend to do it with p5js.

I was thinking about using a serial communication with : [https://github.com/p5-serial/p5.serialcontrol](https://github.com/p5-serial/p5.serialcontrol)  
and [https://github.com/p5-serial/p5.serialport](https://github.com/p5-serial/p5.serialport)

Anyhow if you have started something I would love to see how it works, and probably try to contribute.

Cheers
