PHP-based web front-end for WiringPi's gpio utility at drogon.net
Based on the original work and concept by Travis Brown.
This is a single-page interface to the gpio command line utility used on Raspberry Pi.
It displays the pin names, modes, values, and physical locations as shown with gpio readall.
You can use this utility to change pin modes and values simply by clicking their links. This is quite useful for prototyping, testing, and quickly controlling the Pi from another computer on the network.
This version handles the new double column layout of gpio readall. In addition, it no longer uses
WiringPi-PHP. My version simply uses PHP's exec()
function to call gpio directly.
This is a completely self-contained single page solution, but does require PHP running from a web server,
and of course gpio.
I designed it to run on a Raspberry Pi 3 Model B using apache2 and PHP 5.6, but I see no reason why
it couldn't run in other similar environments. The exec() function must NOT be disabled in the php.ini
file, and the PHP web account will obviously need the ability to run gpio. For standard installations,
I don't expect that this will be an issue.
Ensure that gpio is installed first, which is a utility in the WiringPi package:
cd ~
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build
Ensure that you have a web server:
sudo apt-get install apache2 -y
sudo apt-get install php5
Clone this repository to your web server:
cd /var/www/html
git clone https://github.com/steveeidemiller/gpio-web-utility.git
You can then test with Chromium directly on the Raspberry Pi. Open a new tab in Chromium and type in the following URL:
http://localhost/gpio-web-utility/index.php
This utility is NOT intended to be exposed directly to the Internet or any other insecure network. Because it can control your Pi and has no security features, you should NOT use it in a production environment. It is intended for testing and experimentation only. You have been warned!
