Welcome

The Dallas .NET Micro User Group focuses on the .NET Micro Framework (NETMF) from Microsoft. The group meets on the 4th Wednesday of each month at Improving Enterprises and our meetings are free to attend. Please RSVP according to the monthly meeting announcement to assure plenty of food and drinks for everyone.

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.

A question that I am frequently asked is where NETMF is used commercially. This would be an easy question to answer if we charged for the platform, because then we would know who our customers are. But as an Open Source project, we only hear anecdotally...(read more)

For years, we have tried several of the available serial JPEG cameras and we were very unsatisfied with the performance, the horribly translated documentation and the non-existent manufacturer support. Well, thanks to the creative engineers at GHI Electronics and to the community support, we will finally have a USA made, well supported and well documented serial time-lapse camera with much more to offer. Allow me to introduce you to ALCAM.

When we decided to create ALCAM we did not stop at just making a camera that captures images through UART. We also added SPI and I2C to the supported interfaces, we added an SD card to allow the capturing of images directly to the SD card and then added video Time-Lapse and Stop-Motion recording as well. ALCAM supports resolutions that range from 160x120 to HD 1080 format.

As if that wasn't enough, we also added a stand-alone mode where the camera can be used without any serial commands (without a micro). In this mode, a pin is used to trigger image and video capturing. This pin can be connected to a simple button or it can be connected to a sensor, like a motion detector.

ALCAM was designed to work with ANY micro or development system with access to the serial bus. This includes but is not limited to Arduino, mbed and NETMF. If you can use UART, SPI or I2C then you can use ALCAM!

We have spent months on researching image sensors and lenses but we are not done. While we continue our search for the best suited image sensor and lense, we decided to host a campaign on Kickstarter. We decided to host this campaign to involve our community and the world in helping us make ALCAM a reality. Currently ALCAM is being offered as an OEM board, however, with a successful Kickstarter campaign, ALCAM will also be available as a System-on-Chip. Please back us and let us know how you think we can make this camera even better.

Last but not least, we would like to give a special thanks to the "GHI insiders" for the valuable feedback they provided to us.

We come to you today with two amazingly awesome announcements. The first one is related to the NETMF SDK and discontinued modules. In light of the previous news post about locking the SDK for the entire year combined with the feedback we received from the community, we will be putting most, if not all, discontinued modules back into the NETMF SDK. This should make it much simpler for everyone as we guarantee that these will be in the NETMF SDK for entire 2015 year release!

Speaking of the discontinued modules, we cleaned up our warehouse and will be adding all stocked discontinued modules on the website, as a last time buy and at a ridiculously low price! Make sure you grab what you need before they are all gone.

The second amazingly awesome announcement is about the sale that is happening this weekend. We are giving you 20% off everything in the catalog, however we have also hand picked a few products that will be sold at an amazingly awesome discount. So here it is, your chance to get all of your holiday gifts stocked and ready, without breaking the bank.

We spent the last two years working on major changes on our NETMF SDK, from completely changing the TCP/IP stack to reorganizing the GHI extensions. With the urgent needs of our customers, we had no choice but to make multiple public releases skipping over beta and private releases. This will not be the case moving forward. Here is how we are going to make things easier.

Less frequent releases

Starting with the new year 2015, we will be providing very few public releases, maybe just one. Any updates and fixes will go into a separate optional beta release. We will have as many beta releases as necessary. We will detail what changed in every beta release to make it easy to determine if anyone would need to update or wait for the next official non-beta release. An important note here is that all beta releases will be available only until the next full release is available.

Locking the GHI extension API

The library API is guaranteed not to change for the entire year. Also, any changes in the future will be as backward compatible as possible. Our goal is to make it as easy as possible for you to move to the next release, with no or minor changes on your code.

Old confusing information

There are months old forum posts that talk about the APIs that changed, same goes for codeshare and documentation. We solved the documentation by removing all the old documentation and only showing the new and locked API documentation. Please note that the library references for old SDKs will always be available inside the SDK itself. As for the forum, we will move all old NETMF topics into a separate archive. Finally, codeshare will show a note on any older contributions indicating the new API. We will continue to make our website and offerings easy for new users but also provide support for experienced users.

And the voting begins.....

As we begin our new SDK release cycle in 2015 it is important that the community tell us what they think is important. Please visit Task Tracker, http://www.ghielectronics.com/tracker/list/open , and vote on the issues that you would like to see addressed first.

A special thanks to our community and to the loyal customers who helped in making all this happen.
