Revision history [back]

You need to run the following again everytime you changed/added msg files in your workspace:

  cd <sketchbook>/libraries
  rm -rf ros_lib
  rosrun rosserial_arduino make_libraries.py .

See: http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup#Install_ros_lib_into_the_Arduino_Environment

Note that your arduino code needs to be compiled against the headers in your <sketchbook>/libraries folder, not against those in your catkin workspace....
