A C++ program that handles the Pi Supply switch.
- Log in to your Raspberry Pi via SSH
ssh pi@111.222.333.444
- Make sure that you have git installed
sudo apt-get install git-core
sudo apt-get update
sudo apt-get upgrade
- Go to home directory and Install WiringPi
cd /home/pi
git clone git://git.drogon.net/wiringPi
cd wiringPi
git pull origin
./build
- Go to home directory again and clone this repo.
cd /home/pi
git clone https://github.com/kr15h/PiSupply.git
- Enter the newly created PiSupply directory and Compile using GCC.
cd PiSupply
gcc -o PiSupply -I/usr/local/include -L/usr/local/lib -lwiringPi main.cpp
- Launch application and see if it works. The code inside main.cpp uses GPIO pin 7 to listen for the soft shutdown signal.
sudo ./PiSupply
You might be interested to launch this in background so you can launch other apps and services. I doubt that the PiSupply could be the only reason for using the Raspberry Pi. To launch the application in background, use the following command:
nohup sudo /home/pi/PiSupply/PiSupply &
In my case I've added this to a startup shell script so it is launched when my RPi boots up. I won't explain it here now, there are a lot of different ways to do that.
Hope this will be useful for somebody.
