Dear PIClisters!

Has anybody used a PIC to connect to a CAN bus and is willing to share
experiences? What driver, does it work at all etc...

My application is a science device which will have a computer connected
to several (maybe 20) devices for data aquisition and control. Speed is 
not too important and the distance between the devices is small (about 4m max.)

Or should I go for RS-485? Are there any standard protocols for addressing
etc?

Or maybe I2C?

Well, I am thankful for any advice...

Bye and happy PICin«,

Aki
