Hello everyone! (My configuration: Ubuntu 18.04, ROS1 melodic, x86 intel CPU)

I am struggling with creating a custom message to use in Arduino script later.

My idea was to generate header file (EodImuData.h) and put it into the folder Arduino/libraries/ros_lib/my_folder_with_custom_messages so I can #include std_msgs/EodImuData.h later

I followed the ROS manual: roscustommsg

Basically here is the sequence what I did:

1. Inside existing ros package, begginer tutorial

2. I've created msg folder

3. And added EodImuData.msg file to it. Which looks like that inside the file: C:\fakepath\msg_file.jpg

show it here too:

Header header  
float32 acceleration_x 
float32 acceleration_y  
float32 acceleration_z  
float32 gyro_x 
float32 gyro_y  
float32 gyro_z

• According to the ROS guide, all I need to do is to modify CMakeList.txt and package.xml which I did, attached the screenshots of changes for these two files inside beginner_tutorials

for CMakeList.txt

C:\fakepath\cmakeminrequred.jpg

C:\fakepath\cmakefindpackages.jpg

and for package.xml

C:\fakepath\packagemessagegeneration.jpg

C:\fakepath\cmakeaddmsg_files.jpg

• after these changes to CMakeList.txt and package.xml I go to the ~/catkin_ws folder and apply catkin_make command

After these actions I am expecting that folder catkin_ws/src/devel/include/beginner_tutorial will appear with EodImuData.h file inside, which I can copy to the Arduino/libraries/ros_lib/myfolder and #include it in my arduino script.

But, folder catkin_ws/src/devel/include/beginner_tutorial never has been created, so EodImuData.h file

I've tried another way, but looks like this one isn't correct one, I mean the command:

rosrun rosserial_client make_libraries Arduino/IMU beginner_tutorial

This command, yes, creates the folder Arduino/IMU with all standart libraries (headers files for bunch of common messages), but not a folder beginner_tutorial with header file which based on my custom EodImuData.msg file.

What am I missing/don't understand?

How can I get header file based on my .msg file to use it in Arduino script after?

Unfortunately can't attach CMakeList.txt and package.xml files, only pictures are allowed.

Thank you in advance!

Best, Andrey
