I looked for some time for a decent pi console for doing basic GPIO interaction. I was more interested "at the time" in making light chains and the such. After days of not finding what I wanted I decided to just make one. So attached is a zip containing the 'Simple Pi Console'. Hope you enjoy.
The Simple Pi Console is very basic, it displays status of the apache server on the pi and the mysql server on the pi. To the right it displays all the basic GPIO pins (for out mode) and their current status. We have the ability to make a gpio turn on, off and run through an interval. On the bottom we can manually type shell commands to your pi.
Install is as simple as dropping it into a directory accessible to Apache and navigating to the url.
