Use Phidgets Wirelessly with the SBC

The project described here is a self-contained web server on the Phidget Single Board Computer (SBC). We compose and serve a complete HTTP page within C, and include Phidget data on it. We also accept data to control attached Phidgets in our request.

As with any of our described projects, Phidgets takes care of the electrical component design. Here, we also provide in-depth instructions on installing external libraries on the SBC from source, and from an SVN trunk. We then show how to use the microhttpd.h library within C code to communicate with and control attached Phidgets.

Note: This is a complex way of doing something that the SBC can do much more simply. This page uses the simple example of using an Interface Kit over the network to demonstrate the much more complex concept of using embedded C HTTP servers. An embedded server is a powerful beast, and wanting to create one probably means you've grown needs above and beyond our simple Application Guides. The simpler guides are:

• If you just want to get Phidget data over the network, the SBC already does this naturally from the time it ships. We show an application in the Use Phidgets Wirelessly with the SBC guide.
