Did you try changing the can_bit_rate
argument in the launch file?
https://github.com/astuff/kvaser_interface/blob/ros1_master/launch/kvaser_can_bridge.launch
I have. I believe the issue I am having is due to the code seemingly not supporting bit rates outside of the ones listed below in the screen shot taken from the "kvaser_interface.cpp" file. I have also included a link to the code section I show. I am uncertain if this is truly the issue, however this seems to be where the "bad param" error is originating from.
Interesting, I didn't know there were preset options like that. I'm not actually familiar with this codebase :smile: Those bitrate constants are defined here in the kvaser canlib source code: https://github.com/astuff/kvaser-linuxcan/blob/master/include/canlib.h#L393-L428 So maybe it's a limitation of canlib. Regardless, you'd probably want to look through Kvaser's canlib docs to see if/how you can use bitrates other that those defined.
For a quick test, maybe try hardcoding the input parameter freq
on this line:
https://github.com/astuff/kvaser_interface/blob/ros1_master/src/kvaser_interface.cpp#L101
to whatever it is you want, 333000?
I am working with a CAN bus that is transmitting at 33300 kbps and when launching the node I get an error for a bad input parameter. I was wondering if it is possible to setup the current code to operate at that transmission rate or if there is a recommended way to edit the code base to implement this bit rate. Any and all assistance if greatly appreciated.
