* Visual Studio 2008 or newer (for Windows development).
* Windows XP or newer (for Windows development).

* 96 MB RAM (Minimum); 256 MB RAM (Recommended)
* 50 MB hard drive space.
Developers can download the Octane SDK libraries though the Impinj Support Portal.
If you've read my Hello World LLRP post, you realize how much code is required just to read tags. The equivalent C# code for the Octane SDK is posted below. Before you give it a try, you need to take care of a few things first:
1. Download the Octane SDK from the Impinj Support Portal.
2. Create a new Visual Studio console project.
3. Create a new sub-directory under your project called 'lib'.
4. Extract the SDK files (.DLL) to the lib directory.
5. Add references to these libraries by selecting Project->Add Reference from the menu.

tag.Epc, tag.AntennaPortNumber);
}

// Write the log message to the console.
LogEntry entry = args.Entry;
