VS2010 Support coming for the .NET Micro Framework

Microsoft have announced plans for v4.1 of the .NET Micro Framework! 

We are working on a version 4.1 release that includes (pending any last minute contributions):

  • – VS 2010 support
  • – The Hashtable proposed on the discussion and contributed by Ed Harlow
  • – Open Source TCP/IP and SSL
  • – DPWS enhancements
  • – Big Endian support

We don’t have any dates to share yet – but we will have beta firmware for Tahoe-II and Meridian/P as soon as we are able.

BETA firmware for .NET Micro Framework v4.1 available for Tahoe-II

Microsoft released a refresh to the 4.1 beta late last week and we have firmware available for you to try out on Tahoe-II!

One of the biggest reasons to take a look at this is the support for Visual Studio 2010 (including the express edition).  Other features are listed in this post.

The downloads page has the new Tahoe-II firmware and a new SDK. 

Something to watch out for when converting your projects: VS2010 does a good job most of the time, but we have found at least one instance where it wasn’t 100%.  If your application is not working correctly (especially when deploying or starting), either review the .csproj file and make sure it is not referencing the 4.0 tools, or create a new project in VS2010 and move your code into it.

Let us know what you think.

Micro Framework v4.1 Firmware Released

Yesterday, Microsoft announced the availability of v4.1 of the .NET Micro Framework.  This has a number of new features (including support for Visual Studio 2010) and is the first release to include code contributed from the community.

You can try out this new release on Tahoe and Tahoe-II boards.  The new firmware, and supporting SDK is available for download here.  An update to our Board Support Package and firmware for Meridian/P will follow in the next few days.

.NET Micro Framework Board Support Package for Meridian CPU

Today we are very pleased to announce the release of a .NET Micro Framework Board Support Package (BSP) for our Meridian CPU and development boards.  The BSP adds Meridian specific code to v4.0 of the .NET Micro Framework Porting Kit released by Microsoft late last year.   It means you now have control over every aspect of the code on a Meridian device AND all the tools to do so are FREE!  Yes – the BSP is available to download from our web site at no charge.

You need the Board Support Package to develop custom images for use on Meridian based hardware.  We have included everything you need to build the same firmware we build for Tahoe-II, Tahoe and Meridian/P boards.  With the BSP, you can:

  • Support custom Meridian-based hardware.  You can ensure the right set of software features are included in your image, and that they are configured for your new hardware.
  • Develop custom device drivers.  Sometimes you need to support custom devices and can’t do it in C#.  You may also need to modify existing drivers.  Native code is the place to get this done.
  • Speed-up time-critical code.  For that algorithm that has to go as fast as possible, you can use the interop functionality in the .NET Micro Framework and move it into native code.  This will give you a significant performance improvement.
  • Support a new LCD.  You can do this with the tool from Jan Kucera, however you will speed up production time by creating dedicated firmware that supports your display.

The Porting Kit is quite a complex beast – especially when compared with writing applications in C#!  Before you jump in, you should have a reasonable knowledge of C.  We have provided some batch files and a step-by-step guide to get you started with setting up the build environment and doing your first build.  From there you can dive into the porting kit documentation.

Just like the Micro Framework Porting Kit, we are providing the BSP for free!   Of course, we are not able to include any support at this price :-)  We will try to answer simple questions posted on the forums, but you will need to purchase support for complex questions and issues that require investigation.

As always, we value your feedback on all of our products and love hearing about your projects!

5 Ways to get Support for Tahoe-II and Meridian

Here are the best ways to get answers to questions about our products:

  1. FAQ.  Check out our just added Frequently Asked Questions section.
  2. Forums.  Search the forums to find answers or sign up and post a question.  You are also very welcome to answer questions!  We will have more about opportunities to join our support team in a future post.
  3. Check the Help File.  The SDK comes with a help file that integrates into Visual Studio.  The reference section covers all Meridian and Tahoe specific functions.
  4. Check the downloads page for new SDK or firmware releases.  We may have fixed the issue you are struggling with.
  5. Premium Support.  We do our best to answer simple questions on the forum, however issues that need engineering time need to go through our paid support channel.

.NET Micro Framework v4.0 is shipping

We have just released final v4.0 firmware for Tahoe-II and a new SDK to go along with it.  This is what you need to get v4.0 working with the latest Microsoft release.  Download it here.

Why should you look at 4.0?  Apart from some nice new features, there have been a lot of small changes in both the Microsoft code and our code, which adds up to a faster and more stable product.

This Microsoft blog post has  all the details on features and changes in 4.0, as well as download links for their new SDK.

We have Tahoe-II firmware available now, but expect to see support for our other boards (including the original Tahoe) in the next week.  Once that is done, we will be finishing up a Board Support Package (BSP) so you can work with the Porting Kit on Meridian and Tahoe.

UPDATE: v4.0 firmware for Tahoe, Tahoe with Ethernet add-on board, and Meridian/P is available now.

UPDATE: v4.0 firmware for Meridian/P with the Ethernet board is now available.

Supporting a new LCD

Supporting a different LCD on the Tahoe-II (and MeridianCPU) has just become a whole lot easier thanks to Jan Kucera and a new configuration tool he has released.

The .NET Micro Framework includes a dedicated space for configuration data, and we use this to store the LCD configuration (and a few other things).  This new tool allows you to setup the LCD parameters from a PC.  This means you don’t have to use the porting kit if all you need is a different display.

You can also:

  • Specify screen rotation
  • Choose to show or hide the logo (if you have the porting kit and BSP you will be able to change the logo)
  • Remove the green debug text that appears at startup.
  • Setup the debug transport (Serial, USB or Ethernet).  Useful for Meridian/P where there are no buttons programed for this task.
