TI中文支持网Part Number:IWR1443BOOSTOther Parts Discussed in Thread:IWR1443
Hi Technicians, I have a problem with combining IWR1443 with NVIDIA JTX. The environment in NVIDIA JTX is Ubuntu18.04 and ROS melodic. Downloaded mmWave ROS driver with ti_mmwave_rospkg package via git clone git.ti.com/…/mmwave_ti_ros.git. The catkin_make compilation was also successful. But when I connected the IWR1443 to the NVIDIA JTX through the docking station, I ran roslaunch ti_mmwave_rospkg 1443_multi_3d_0.launch without any error or point cloud information. So I connected IWR1443 to my laptop, and also configured Ubuntu18.04 and ROS melodic. After running roslaunch ti_mmwave_rospkg 1443_multi_3d_0.launch, you can see the corresponding point cloud information. I would like to ask what may be the cause of the problem that there is no point cloud information when IWR1443 and NVIDIA JTX are combined?

请问是通过什么接口和IWR1443连接的？
,
?? ?：
一个扩展坞，集线器H01-3.0。最开始会报端口权限问题，运行sudo chmod a+rw /dev/ttyACM0 和 sudo chmod a+rw /dev/ttyACM1 后就没有报错了

建议直连，不建议用拓展坞，有时会出现问题。

iwr1443原理上可以使用扩展坞吗？我这边小车上接口不够

Shine：
网口，USB口我们都要求直连的。您先直连一下看看，排除拓展坞的问题。
