Hi Mr Hermans
I could work cansend command but i couldn't see outgoing data.Could I see
datas with oscilloscope? I tried but couldn't see anything wonder if
what's wrong

Hi Andrew ,
I think you misunderstand me.I couldn't active BBB's CAN legs.So i
couldn't use CAN .Then i couldn't find to using of CAN Bus with BBB .So i
want to learn Beaglebones Black's how to CAN leg could do active and
starting communication.But at this link commands didn't
In the comments from the linked article you have this message:
which cape is this tutorial for? I also have several TowerTech Can capes.

To which the original author responds:
I did not use any cape when making this tutorial, I
Huh? CANOpen/SocketCAN SDO transactions can have almost indefinite extent,
have toggle bits that persist across frames, and CRC's that span the whole
transaction.
If you can eyeball that, you are way smarter than me.
I think you may only be considering PDO transactions which are only ever 8
You don't get a choice. CAN *requires* a transceiver to convert from the
TX/RX signals on the Beaglebone into the differential bus
dominant/recessive that is the physical layer for CAN.
In addition, you must have *TWO* can nodes in order to test communication.
CAN *requires* an ACK before it
*Side note: wireshark is capable of decoding CAN packets and even the
SocketCAN protocol!*
This is something I guess I'll never get. Whats the point ? socketcan
frames only have up to 8 byte data payloads . . .candump, and a good eye
for your data is all that is needed.

*Thank you Andrew for your suggestion.But i don't want to use any extra
hardware.I want to use direct BBB.Wonder if i couldn't find Can Bus
driver for BBB ?*
Good luck with that. It is my understanding that you *have* to have a cape,
or at minimum logic level translation in order to use

Well, you need a CAN cape of some form to provide a CAN
Well, you need a CAN cape of some form to provide a CAN transceiver.
Something like this:

After that, follow the directions that the manufacturer provides.
