How to Use the GUI Log

The log screen in the GUI shows the serial data sent to

Arduino to control its API functions.

ii. Start Motor Rotation

iii. Stop Motor Rotation

iv. Free Motor Rotation

19. Saving the GUI Log

By pressing the “SAVE” button, the content
displayed on the work log can be saved as a .txt
file or a .csv file.

20. Clear GUI Log

By pressing the “CLEAR” button, the content
displayed on the work log will be erased.

21. Program Generation

Pressing the “Generate Program” will output the
executed API functions on the work log into a .ino
program file that can be uploaded directly with
Arduino. By writing the output of the .ino file to
Arduino, motor control can be executed
automatically through standalone operation
according to the procedure generated through the
GUI Log.
For more details regarding the Arduino program
generation function, refer to the attached Appendix
under 

21 Arduino Program Automatic Generation
