AWR1443: Problem with awr1443 ros driver demo project

Part Number: AWR1443

Hi, all

    I'm trying to run the lab "Ros Point Cloud Visulizer" in mmwave sensor / industrial toolbox.

    Environment setup configurations are： Ubuntu 16.04  + rosdistro: kinetic  (desktop-full)  + ti_mmwave_rospkt: ti_mmwave_rospkg_v1p2 (the latest ver)

    I followed the instructions in ti mmwave ROS driver setup tutorial, when i tried to run "roslaunch ti_mmwave_rospkg rviz_1443_3d.launch", I couldn't see point-cloud info in RVIZ window and got following errors in terminal :

I'm not familiar with ROS. It seems that the commSrv nodelet hasn't been loaded successfully, the errors show that mmWaveCLI service isn't called, i think the sensor has not been started yet.

So anywhere wrong ? Anyone can help me ?

Thanks

    Hi, Cesar

    Thanks for your attention. I got some infomation from thread e2e.ti.com/.../619401
    Now I fixed it , thanks.

    Btw, whether the ti_mmwave_ros_pkt support rviz with CAN interface ? (The ROS Point Cloud demo got data from serial in default).
    I want to do this, maybe can driver for ros is needed ?

    Lin,

    Glad you found the previously posted work-around for XML error issue. That fix will be released in the next TI mmWave ROS driver release.

    The TI mmWave ROS driver relies on the the mmWave SDK out-of-box demo running on the mmWave sensor EVM and the SDK demo currently only supports the serial/UART interface. There is a CAN driver included in the mmWave SDK which could be used to modify the out-of-box demo to output data over CAN instead of UART. The ROS driver may also need to be modified to use the CAN interface on the PC.

    Please mark as answered if your question is resolved or reply if more support is required.

    Regards,

    Thanks, JohnH.

    I modified the out-of-box demo with CAN driver provided in SDK, now output data can sent over CAN.
    But I have problem on CAN interface with ROS driver. Any examples about this ?

    Lin,

    We do not have any ROS driver CAN bus examples, but I did see some existing ROS packages for the CAN bus online when I did a quick search for "ros can bus" on Google.
