@Uhv I think you'll be better off getting a hold of a premade CAN => RS232 device if you do not want to try building Espruino yourself. This is especially true if you project relies on CAN then you should have a way of debugging the bus.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Maybe something like this: http://www.canusb.com/ ?
I guess @Gordon will move this thread as he sees fit :)
