Is it possible to write unmanaged code for the Netduino but still take advantage of all the drivers, etc. available to C#??

[Chris Walker]

Hi Charles, Yes, you can write native C++ and compile it directly into the open source Netduino firmware. We're also working on a way to integrate C++ code at compile-time...but it'll take a while to get that completely implemented. C# is great for "command and control", and your native C++ code can do the time-sensitive tasks... Chris

Hi Chris, So how would I go about doing this? I get your Netduino firmware project and then write some C++ classes which I have to include in the firmware somehow? Thanks.

Thanks.

You can write C++ code--and then create C# wrappers to call it. You can also write C++ code that runs behind the scenes (via IRQs, FIQs, completions, etc.)

Here's a good example/tutorial:

Cool - I'll have a look at the example/tutorial. Thank you very much.

You might also want to check out Steve Maillet's Using Interop in the .NET Micro Framework V3.0, and Adding Features to the .NET Micro Framework by Interoperating with Unmanaged Code chapter in the Porting Kit documentation.

Additionally, several interop projects with complete source code have been already published in the forum (BitBanger by sweetlilmre, OneWire, Corey Kosak's famous Fluent Interop 1.6/1.4/1.2/1.0, and others).
