In ROS2, is a wall timer connected to a node in a way meaningfull for a user
Hi, I need an object (a node) to create a timer in ROS2. I can create any node just in order to call the respective method create_wall_timer
, but I would like to have a timer which calls any generic callback not connected to a ROS node. I guess it works like that but you need a node for some technical reasons mentioned here https://groups.google.com/forum/#!top... ?
