I finally got around to finish and post the first release of the Phidget devices.

It is available here: http://blogs.msdn.com/irvingd/pages/biztalk-rfid-device-provider-dspi-for-phidget-devices.aspx

Additional updates will be posted in this blog.

I'll be posting sample snippets on how to access the devices using BizTalk's synchronous command model.

The code is based on a managed hardware abstraction layer I wrote to deal with the low-level hardware commands. I'll describe it and demonstrate how to use it in future articles and posts.

Please post comments and questions in my blog!
