Dear all
for a photobooth project I want to use different (Remote buzzer) hardware buttons and a rotary encoder (KY-040), which should be connected to the GPIO pins.
I have a working configuration on a Raspberry Pi 4.
The webserver application will watch GPIOs for a PIN_DOWN event - so the hardware buttons need to pull the GPIO to ground, for to trigger. This requires the GPIOs to be configured in PULLUP mode.
The used GPIOs are defined in the boot/config.txt as follows:
gpio=16,17,20,21,22,26,27=pu
Can I use the same configuration / GPIO pins on the Rock 5?
For further information on the project please see: https://photoboothproject.github.io/FAQ#can-i-use-hardware-button-to-take-a-picture
Thx Frank
