Andrew's Project Blog: Hardware, Software, Stuff I find Interesting

I've been quiet on here recently as I've been working on a new open source project.

It's finally in a state to make public:

It's basically a microcontroller board that looks like a file system to the computer. So write "1" to a "io/pins/0" will turn on pin 0, write "0" and it will turn it off. There's also the ability to add a 'device' files which hide interface code behind a file. So you can write "1234" to a file and the phatIO device will do the interfacing to get it to a LED display etc.

No drivers, or serial libraries just files - it radically simplifies controlling things. Because its a filesystem, it can be upgraded by dragging a new system image to a boot directory.

Devices with beta software are for sale at along with a manual, and some example projects. More to follow..

Set a pin to 5V by saving "1" to its control file, set it back to 0V by saving "0".
