QCanBus compatible hardware

ocgltd

I want to play with reading/writing CANbus frames to my car. Since I want to use Qt, is there a list of Qt compatible CANbus to usb interfaces?

If not, is there a discussion of which one(s) work best?

@kuzulis Thanks - I found that one (through other forum posts) but it seems very expensive. I see entire rasberry Pi's with CANbus hat's for $100...I was hoping for something in the $50-$75 range. I'm not sure if the Qt lib requires more intelligence in the CAN controller...

I found a list of compatible products here:

Looks like there is no support for the very inexpensive raspberry hats. Has anyone written a plugin for Copperhill Technologies CANbus interfaces? They seem very inexpensive and very flexible. As I'm new to CAN this is likely beyond me at this point.

AFAIK, your dongle does support the SocketCAN API, which is supported by QCanBus. But you can use it only in Linux.

@kuzulis I'll want to do all of my analysis (capturing frames) in Windows for ease of use, by my app will run under Linux. So I guess I'll have to go with Peak which appears to work in Win and Linux.
