ラズパイ4デジカメ計画①〜格安の(サポートの終了したWiringPI系)液晶タッチパネルを使えるようにする

            + Bookworm以前、以降でシステムの中身におおきな壁がある
+ WiringPiはもうサポートされないため、BookwormやRPi5だと論外

            This is wiringpi.com.
As of the end of 2023, you'll not find anything here anymore. It's gone.
Email if you want - if you know my email address. Work it out.

            As of 31st October 2023 nobody has shown an interest in properly maintaining it.
Between this, and changes to GPIO in Rasberry Pi OS Bookworm and on the Raspberry Pi 5,
this project is going nowhere.
It has been archived to more clearly indicate this status.
