What is NETMF?

.NET Micro Framework (NETMF) is an open source platform that expands the power and versatility of .NET to the world of small embedded applications. Desktop programmers can harness their existing .NET knowledge base to bring complex embedded concepts to market on time (and under budget).  Embedded Developers can tap into the massive productivity gains that have been seen on the Desktop.

The F20 SoC (System on Chip) is now in production and ready to ship. Products can now have full access to files and folders on SD cards with very minimal resources. Priced at around $6, it is a more economical option than investing in building and debugging file system libraries. The F20-uSD board is a low-cost OEM board with the F20 SoC at it's core, an ideal board for quick integration or evaluation of the F20 SoC.

We are also improving the overall file system offerings. First, the original ALFAT chipset has been renamed as the F40 SoC. Only the product name has changed, the ordering part number is the same, ALF2X-SC-512. Second, we are introducing the GHI Electronics' File System Command's Manual, which covers all commands for all of GHI Electronics' file system products. There are also datasheets that cover the specifics of the individual products.

We are also excited to release a new firmware for the F20 family that adds a few useful features. The new datasheet has more information on what is now supported and an updated pinout. See the developers' guide for more information on updating the firmware on the F20 SoC and related products. Unfortunately, the new firmware and any future releases are not compatible with the F20-uSDs shipped to date (those that have a GHI bootloader version of 2.0.2). They will still work great with the full-featured existing 0.5.0 version of the firmware.

We would like to introduce the newest member of the Octavo Systems family of products (drum roll please), please welcome the OSD3358 TH Module! The OSD3358 TH Module is based on Octavo's OSD335x System in Package (SiP) which incorporates Texas Instruments' powerful Sitara™ AM335x processor with an ARM® Cortex®-A8 core. With all of the complex and sensitive components being handled internally by the OSD335x SiP, designers can easily harness this significant horsepower for their designs.

For those of you wanting a low-cost option for taking the OSD335x SiP for a test drive, the OSD3558 TH Module is the perfect solution for you! We added 60 holes exposing everything from ethernet to CAN, all you need is a breadboard and an idea! We even made it Fast and Easy for you to add displays by providing the pinout for the Display NHVN Module. To get started creating your next master piece, all you have to do is plug in a USB cable and you will be on your way to greatness.

But that's not all, in preparation for accepting preorders, we have added pricing to all products in the Octavo Systems ecosystem. Take a look around and start making your Octavo Systems wish list!

Guess who is going to be at the 2016 Bay Area Maker Faire? You guessed right, we will be making the 2,090 mile trip from Detroit to San Francisco in just a few days! If you are in the area and would like see to us in all of our embedded glory then stop by booth 2434 and say "Hello".

Why are we going? We will be volunteering in the BeagleBoard.Org Foundation booth and talking about how awesome we are and how much we love the team at the BeagleBoard.org Foundation (but mostly about how awesome we are!) We even helped in creating a couple of demos, so please feel free to stop by and see what's cooking with GHI and the Foundation!

Today, we are excited to announce the partnership between GHI Electronics and Octavo Systems. Octavo's OSD335x System in Package (SiP) incorporates Texas Instruments' powerful Sitara™ AM335x processor with an ARM® Cortex®-A8 core. With all of the complex and sensitive components being handled internally by the OSD335x SiP, designers can easily harness this significant horsepower for their designs. On the software side, the processor used is the same processor utilized by the BeagleBone Black designed by the BeagleBoard.org Foundation. The entire ecosystem, from the community to the software, is available to be used on the OSD335x SiP.

GHI Electronics' OSD3358 Development Board is the official development and evaluation board for the OSD3358. The OSD3358 System on Module (SoM) provides yet another foot print for the OSD3358 family of products. The OSD3358 SoM simplifies the design even further by adding 4GB FLASH memory, crystals and other required circuitry. A power source is the only thing needed to utilize the OSD3358 SoM. The SoM can be hand placed for prototypes and also machine placed for full-blown production needs.

For fans of Microsoft products, the good news continues! We are working with Microsoft and other partners to make all of these amazing offerings easier to use with Microsoft technologies such as Microsoft Visual Studio. Click here to learn more on how to use Visual Studio to program the OSD3358 family of products.

Today we're releasing the NETMF SDK 2016 R1 Pre-Release 2. As long as there are no major issues, this is planned to be the last pre-release for this SDK. Changes in this pre-release are mostly minor. See the release notes for complete details.

- Fixed built in Ethernet LEDs not working
- Fixed various minor issues around CAN, USB client, CDC, and SPI
- Fixed COM2 handshaking on G120 failing due to a pin reservation issue
- Minor networking improvements
- Minor Gadgeteer fixes
- Added SmsSent to Cellular Radio
- Added TinyBooter update in IFU to EMX
- Added the ability to select the COM port used for loader updates in FEZ Config
- Improved loader update instructions and choices in FEZ Config

There are two bigger changes though:

First, we have updated our code signing certificate. You may get warnings that the SDK installer, USB drivers, and FEZ Config are not well known from Windows since it is a new certificate. This will go away as the SDK is used more.

Next, our devices no longer need the USB driver for MFDeploy, Visual Studio, and FEZ Config to see them. They now expose the proper USB configuration needed for Windows to automatically configure them as WinUSB devices and for Micro Framework to discover them. This requires a new TinyBooter for every device though and will only work for devices using the 4.3.8.1 firmware or later.

Additionally, Windows 10 also automatically configures USB serial ports. This means that the USB driver for the GHI Bootloader Interface is no longer needed on Windows 10 and above.

So if you are on Windows 10, are using the 4.3.8.1 firmware or later, and do not need the signed CDC driver, installing the USB driver package is now optional, though everything will still work fine if you do install it. Our SDK installer will still install it by default for now.

Lastly, while we still do not officially support it, we are making an unsupported patch available that allows you to use Visual Studio 2015 with our SDK. The issue with unsupported IL can manifest itself in very weird and subtle ways causing your program to behave erratically or in seemingly impossible ways. We recommend Visual Studio 2013 for production use.

Make sure you are using the latest Gadgeteer core as well.
