Raspberry Pi GPIO Safe Shutdown and Wakeup Solution

Overview

This project provides a simple and reliable way to safely turn your Raspberry Pi on and off using GPIO pins and the run/reset pad at the backsite, preventing data corruption and ensuring safe operation. It's compatible with any Raspberry Pi model, including the Raspberry Pi Zero 2W.

Key Features

• Safe shutdown using GPIO pins.
• Optional LED indicator for power status.
• Prevents data loss and system corruption.
• Works with any GPIO pins on the Raspberry Pi.

Installation

Follow these steps to modify the config.txt for safe shutdown:

1. Open the config.txt file located in /boot/.
2. Add the following lines:

   
   gpio=27=op,dl
   dtoverlay=gpio-shutdown,gpio_pin=17,active_low="y"

From the command line:

sudo sh -c 'echo "gpio=27=op,dl" >> /boot/firmware/config.txt'
sudo sh -c 'echo "dtoverlay=gpio-shutdown,gpio_pin=17,active_low=\"y\"" >> /boot/firmware/config.txt'
