Hi,
I installed OAP in my car last week but the reverse camera view is not being brought up automatically when I shift into reverse. I set the trigger pin to GPIO 23 within Open Auto's camera settings but nothing happens when I shift. I can manually bring up the camera view by pressing the camera button on the home screen, but that is clumsy and inconvenient. I need it to bring up the camera automatically.
I attached my wiring diagram below (DC barrel jack represents power from the car battery and LED represents the reverse lamp light bulb). I used a PC817 opto-coupler with a 680 ohm resistor between the reverse lamp and the Raspberry Pi to mitigate risk of power spikes impacting the Pi. Any help is appreciated.
