I will be needing to build a CAN network interface using the NANO. Any experience out there?
What hardware is required? Do I need to use some chip or another?

Thanks!

I have done some CANOpen development on MOD5234 and MOD54415, but I have never worked with a NANO. I expect you will at least need a CAN tranceiver (SN65HVD232D on the NetBurner mod-dev-100 board).

I believe I tested the canif and multican drivers against the NANO dev board with the can2serial example (Note: this example will require two devices to talk to each other). Essentially Ronald is right though, about the only thing you need is the SN65HVD232 IC and possibly a couple termination resistors. The datasheet has recommended layout considerations http://www.ti.com/lit/ds/symlink/sn65hvd230.pdf, but if you just want to try something quick, you could always try to get the NANO in a dev board to talk to something.

Thanks guys, The Dev board it is!

Chris,
the thing with CAN is the messages are acked.
So to transmit you require a receiver that is actually configured to listen for that packet.

Unlike a serial port where you can send with no one listening, sending on CAN without a receiver actually listening will generate errors....
This is the biggest logical change you will have to un-learn to use CAN.

IE its impossible to test CAN on a single board, you must have two....

In other words, CAN is the anti-highlander: there can never be one...

You guys are killing me...."the anti-highlander"

I have previously purchased a Microchip CAN dev board set- will press them into action...

and Paul- thanks for the words of wisdom.

!!CAN!!

Now the world will be at my feet!!!
