  1. Locate to the directory where the test code, basic_edge_detection.py, exists:
    1. Execute the following command to get the directory where VisionFive.gpio exists: 
      pip show VisionFive.gpio
      Result:
      Location: /usr/local/lib64/python3.9/site-packages

    3. Execute the following command to enter the sample-code directory: 
      cd ./VisionFive/sample-code/
  2. Under the sample-code directory, execute the following command to execute the demo code:
