momentary off button advice

[davezx]

I've been looking at this guide for a off button with script for shutdown procedure.

These pins here.

It looks like it is for the pi 1 as mine is a pi2 b+ and I don't have the pins advised in the guide to use.
Can someone please advise on the pins to substitute the one's on the guide for the pi2 please.
Thankyou.

You can use any pin you like, GPIO 31 isn't connected to the header op the Pi 2B.
In the code of the tutorial, just change:

Code: Select all

GPIO.setup(31, GPIO.IN, pull_up_down = GPIO.PUD_UP)
GPIO.add_event_detect(31, GPIO.FALLING, callback = Shutdown, bouncetime = 2000)

to:

Code: Select all

GPIO.setup(x, GPIO.IN, pull_up_down = GPIO.PUD_UP)
GPIO.add_event_detect(x, GPIO.FALLING, callback = Shutdown, bouncetime = 2000)

where x is the GPIO number you used.

That's good news thank you.
Can I write this in terminalx? And save it there.
