The project is a Windows Form that communicates (using XBee S1) to a FezSpider that has one button and a GHIElectronics.XBee module. The Honeywell HMC6343 compass and I2C pullup resistors (10K to 3.3Volts) are located on a GHIElectronics DuinoProto board. I am using Microsoft C# Express.
The complete source code is available at: http://hmc6343project.codeplex.com/
Be advised that the code I downloaded to Codeplex was missing the source code for the User Controls
ClassRotator and ClassSerial. Windows Form folder FezSpiderFormHMC6343.
Codeplex now has the corrected Zip.
Sorry for the error on my part.
