@DerkJ, is the Raspberry Pi working for you?
Here are the modified quickstart steps that work on my 4B Pi:
• New MicroSD (32GB) formatted
• Install Imager and follow directions
• Raspberry Pi OS is now installed
• sudo apt-get update //(This updates the install files)
• sudo apt-get upgrade //(This command performs updates on apps)
• sudo apt-get dist-upgrade //Updates the OS distribution
• sudo rpi-update //Updates the firmware
• Reboot needed
• Install library (sudo apt-get install libunwind8) (should be installed)
• The pigpio is automatically installed and is bundled with the Raspbian Operating System
• Run the command ‘sudo systemctl enable pigpiod’ to start the daemon after rebooting
• Run ‘sudo systemctl daemon-reload’ to reload the boot programs
• Check to make sure it works with ‘sudo systemctl status pigpiod’
• Download Eugene’s free library at Github: https://github.com/eugenedakin/pigpio-GPIO
• Drag and Drop the class into your project
• Add an LED and resistor to Pin #18
• Compile Example5-2
• sudo chmod +x Example5-2
• sudo ./Example5-2
• LED turns on and off when pushing buttons
Edit: Thanks for your help Derk.
