Hello!
I need to access a CAN Bus from my processing sketch. I have not found any processing library that can do it. I have tried it with java and I have not found anything either.
I have a star topology with different arduinos and a CAN hub. I connect a raspberry to the CAN hub and run my processing sketch on the Raspberry Pi.
To the CAN network I connect 2 raspberry Pi with screens and 3 Arduinos, although it would be possible to increase it to 4 or 5 Arduinos.
This would be my main idea, with the CAN proposition.
It would be open to other formulas, with certain restrictions:
- It has to be wired.
-I may need a long cable, about 4 or 5 meters. (Think in a car).
I thought of simply using usb connected to usb hub and this hub connected to a Raspberry pi, but it limits the access of a second or third Raspberry Pi to the data that arduinos offer.
Thank you for your answers!
Don’t know if this is any good? They have nice APIs, including Java, for all their stuff.

Thank you! I think it’s a good alternative. May be a little expensive because I would need 2 “shields” the Brick (Master or Hat) attached to a USB of the Raspberry Pi and the CAN Bricklet attached to the Brick. About 50€ + shipping cost (10€). But there is a really good alternative.
Any other alternative it’s wellcome.
Yes, it’s not necessarily the cheapest solution, but they’re well made / thought out devices, and I like the fact that the whole stack (software and hardware) is open source, and they’re really responsive. I built support directly in to PraxisLIVE and have built a few interactive projects with them, like this (using NFC reader to trigger videos, and IR and rotary encoder to play with them).
