Running Demo Code

To run the demo code, perform the following on VisionFive 2 Debian:

  1. Locate to the directory where the test code, LED_Matrix.py, exists:
    1. Source into the Python3 Virtual Environment: 
      source ./myvenv/bin/activate
    2. Execute the following command to install dependency: 
      python3 -m pip install pillow
    3. Execute the following command to get the directory where VisionFive.gpio exists: 
      python3 -m pip show VisionFive.gpio
      Result:
      Location: /home/user/myvenv/lib/python3.11/site-packages
      Note:

      The actual output depends on how the application is installed.

    4. Execute the following to enter the directory, for example, /home/user/myvenv/lib/python3.11/site-packages as indicated in the previous step output: 
      cd /home/user/myvenv/lib/python3.11/site-packages
    5. 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 run the demo code: 
    sudo python LED_Matrix.py

    Alternatively, you can execute the following command:

    sudo python3 LED_Matrix.py
    Result:

    The Led Matrix module displays with the StarFive logo.
