Procedure:

1. Create New Project  

2. Name the project, Select Board teensey 4.1

3. Create src/main.cpp, paste the code present in src folder. Change the CPR Value for adjusting the angle rotation of motor.    

4. Go to Include folder and make a file named RMCS2303.h and paste the given code:

 

5. Go to src folder and create a file named RMCS2303.cpp and paste the given code:

6. Go to libraries section and search for ros. Download the Rosserial Arduino Library by Michael Ferguson. Select the project name and add project dependency.  

7. Compile the Code and upload to teensey.

8. Run the below commands in separate terminals:-

9. Terminal 1:

roscore

10. Terminal 2:

rosrun rosserial_arduino serial_node.py /dev/ttyACM0 _baud:=9600

11. Terminal 3:
