Banana Pi GPIO nutzen

Hallo,

ich dachte mir die ganze Zeit, was ich mit einem Arduino machen kann, kann ich mit dem Banana Pi, der sowieso seine Kreise dreht, auch machen: Der hat ein Multitasking-OS und kann IPv6, das ist viel

Aber, so richtig mit "GPIO" beschriftete Pins hat der gar nicht.

Ich gehe mal davon aus, dass gpiochip0 der auf dem Board (im SOC?) befindliche GPIO-Controller ist, die anderen gpiochips sehen mir von

Raspberry-Pi-Doku verwenden oder gibt es signifikante Unterschiede zum Banana Pi?

Pullup-Widerstand versehen und dann mit einem Optokoppler gegen Masse ziehen kann. Ich vermute, dass man fast jeden Pin aus seiner dokumentierten Funktion rausnehmen und zum "normalen" GPIO machen kann, aber wie?

Hat jemand schonmal die GPIO-Pins eines Banana Pi verwendet?

Leider stirbt die Plattform ja langsam aus :-(
