I just ordered a mini lcd screen, a mini usb keyboard for one of my raspberry pi units.
Will try to make a little computer to capture stuff while driving.
Will be using python. If I have something to show, will post it here

How hard is it to write a program that will "enable" one or more of the can bus'es and makes a binary dump to a file ?

I think I run into problems with the fact that my laptop is not fast enough for all the graphical overhead of the app & wireshark.
I am pretty sure a CLI would have so little overhead that my old hardware would be fast enough.

Would somebody take a try at this ?

seems like a nice piece of software to gather a lot of can bus data.
Anyone looked at it already ?

I recently started looking for can bus hardware and am glad I found the cbt.
Ordered one, got it super fast.
I just started playing with it.
I can see activity on can bus 1 at 500K speed using the alpha 0.2.6-1 app

I wonder what the 2 red dots with errors mean on bus1

I try to capture with wireshark on a laptop with debian linux using the pipe feature.

I add the /tmp/cbtbus1 pipe interface, hit save and close
It is added to the list of interfaces and already selected (only one)

I hit start. I see packets coming in (but not being displayed in the field that shows data in the example howto ) and than wireshark barfs.
I have no opportunity to save anything.
I am using the stable wireshark from debian: 1.12.6

When I start wireshark from a xterm, I see this when it barfs:

(wireshark:4868): Gtk-CRITICAL **: gtk_window_set_transient_for: assertion 'GTK_IS_WINDOW (window)' failed
20:50:55
Warn Error "Less data was read than was expected" while reading: "" ("/tmp/wireshark_pcapng_cbtbus1_20150706205032_ySueVr")
*** Error in `wireshark': free(): invalid pointer: 0x00007fabb9fab760 ***
Aborted

Should I tell wireshark somehow, what kind of data to expect ?
Is it expecting ethernet frames instead of canbus and therefore quitting ?
