  This repository aims at providing examples to illustrate ros2_control and ros2_controllers

  

Hello, I am learning ROS2_control by trying to wrtie a custom hardware interface to control 2 servo motors via Arduino. I am referencing these two repository ros2_control_demo_hardware and diffdrive_arduino when trying to write my code. I can successfully move my pan-tilt robot in simulation (Gazebo) and fake hardware mode. However, I failed to move it in the real hardware after a week of trying. below is the error i got when i ran the launch file. Can anyone tell me where i did wrong and how should i modify my code to correct it? Many thanks. Here is my code here
