check the hardware connection.
Step 5. Use “sudo tcpdump -n -i eth0” (here eth0 is the name of the wired
network device, see the device name of ifconfig wired connection display for
details) to view the data packets sent by the lidar (as shown in the figure, there
are 1206-byte data packets sent by the lidar to the destination, which means
that the lidar data is sent normally).

4.2.2 Software Operation Example
Step 1. Establish a workspace and build a compilation environment
mkdir -p ~/leishen_ws/src
cd ~/leishen_ws
Note: The workspace can be named arbitrarily. For example, “leishen_ws” can be
changed to any name.
Step 2. Download the Lidar ROS driver
The ROS driver can also be obtained directly from our website or customer
service. Copy the obtained driver file to the newly created workspace “src”, and
decompress it.
Step 3. Compile and package
cd ~/leishen_ws
catkin_make
Step 4. Run the program
source ~/leishen_ws /devel/setup.bash
roslaunch lslidar_c32_decoder lslidar_c32.launch –screen
Reopen a terminal again and execute the following command:
rosrun rviz rviz
