Setup process

1. Unzip the source folder

Python

2. Install Python
   • Install listed modules
3. Create a startup task in task scheduler https://www.jcchouinard.com/python-automation-using-task-scheduler/ Use pythonw.exe for creating a background process (start at logon), usually located at e.g. C:\Python39\pythonw.exe

Alternatively, if you don't have Python installed, use the .exe file

Arduino and PlatformIO

3. Install VSCode and PlatformIO
   • Install listed libraries
4. Plug in the board (USB) and upload (arrow at bottom left)

Configuration file and debugging

6. Change the settings in rotate_screen_config.ini
   • You can execute the python script in a console for debugging purposes with py .\rotate_screen.py (open the terminal in the Source folder) or open rotate_screen_console.exe
