The user-interface for this project is a GUI program that sends bytes to a real-time fifo using the same protocol used in project 2 (you can even test it with you project 2 ppservo module to verify that it works.) To run the interface you need to download the following two files:
The first file is the actual executable file. To run servo.py, you may have to make it executable first by running "chmod 755 servo.py". The proj3.glade file should be in the same directory as servo.py.
The value written to the real-time fifo is controlled with a scroll bar. By default the program writes to /dev/rtf4. The fifo used can be changed by replacing /dev/rtf4 with the appropriate real-time fifo device file.
