Power off button (on GPIO) #2404

Open AN4LOG2K opened 4 years ago

AN4LOG2K commented 4 years ago

Is there a way to add a physical button (such as a momentary switch connected to GPIO 3 or a combination such as GPIO 21 & ground) to power off safely both motioneyeos & the rasp pi. I am using a pi zero W / dev20200223 / pi cam v2 .

The reset (RUN) button could be used to switch the whole system up again.

The goal is to make a portable camera that can be activated and deactivated with the push of a switch when needed without the need for SSH or a Browser.

Cheers

Yes. There is a GPIO pin and a dtoverlay file that can be copied into the /boot partition and a couple of lines into config.txt There is a good set of instructions at https://forums.balena.io/t/dtoverlay-gpio-shutdown-and-gpio-poweroff-options-not-working/36467

Hi there thank you for your answer. I haven't had the chance to work on this project yet unfortunately. But I will get back to you once I have successfully managed to do it.
