I have added another release to the Grommet Library (an extension to the .NET Micro Framework). This release adds default comparers to OrderBy and ThenBy to allow the use of the orderby C# keyword. The code sample from the previous post can now be simplified with the orderby keyword: var feedsToUpdate = from feed in feedList orderby ((RssFeed)feed).LastUpdate descending, ((RssFeed)feed).Name where ((RssFeed)feed).LastUpdate > new DateTime(2009, 03, 20) select (((RssFeed)feed).Name); Also, this...

To be honest, I haven’t been working on my entry to the Dare to Dream Different Challenge lately. I was distracted by a comment on my blog by Jens Kühner correcting my post where I stated that Linq was not possible without generics. Well, that got me searching, and I could only find proof implementations of Linq without generics, but not a full implementation of Enumerable.cs targeted to the Micro Framework. So I started writing one. Although, it is not complete yet, I thought it was far enough along...

I have been busily working away at building infrastructure for the Dare to Dream Difference Challenge. Since my last post, I have finished the hardware prototype, although I still need a cabinet. The project now consists of a Device Solutions Tahoe II development board, an XBee Series 2 module, an AR1010 FM Receiver, an LM4832N audio amplifier, and two 0.5 watt speakers (pictured here). Not pictured is the ZigBee base station. I have made a shift in the approach I was taking for the software. Originally,...

After a week of coding, I now have the first signs of a bedside clock! The first milestone of my project was to get the XBee network stack up and running where I would have a desktop computer and an embedded device talk to one another. To reduce the risk of getting both devices talking I wanted to have the exact same code run on the desktop and the embedded device. I went about this by creating a class library project targeted at the .NET Micro Framework and another class library targeted at the...

Now I am officially in round 2. I didn’t realize I had to fill out some forms to make sure that I met the contest rules. Fortunately, that is all behind me now, and my development board is on it’s way. Which doesn’t give us contestants a lot of time. Round 2 ends March 31, 2009, which is a little over 2 months away. I plan to blog about my progress. Right now, I am in the “getting reacquainted with Micro Framework” that I last looked at a couple of versions ago. I had bought the book “Embedded Programming...
