8 years ago Hi,
Yes, I saw your message on the LCM list. LCM is a message passing system, similar to ROS pub/sub, but with some small differences. There is no master in LCM and traffic is sent via UDP multicast. There are some good tutorials here: https://lcm-proj.github.io/tutorial_general.html

Hi I am super new to LCM an just went through homepage about the introduces and tutorials. But it seems no detail tutorials. I have experiences in ROS but want to use some small framework to develop our project. Algorithm processed in onboard computer( arm ubuntu) with copter to avoid obstacles.
Can I ask questions about framework which integrated in your whole project. Is that LCM connected every module together like several ROS nodes with pub/sub mechanism. It seems that LCM use broadly in multi-mechines communication not computer threads.
I try to use the flight controller API (drone-python) http://python.dronekit.io/ to communicate between onboard computer and Pixhawk which uses APM copter firmware. Because that's more stable and functional API. And stereo-camera with opencv to acquire obstacle data in c++, like depth map, etc. I wan to use LCM sub/pub message mechanism to wrap this two modules. maybe more modules in the future. Is that possible?
Please correct my misunderstanding and give me some suggestions. Thanks for your help.
