Over the last few weeks I have been quite busy with my MPPT Solar Charger project. I’ve built up a first board and started writing firmware for it. Since the last version was not too different in terms of hardware I was able to re-use most of that code. But I hadn’t even touched on the whole USB stuff back then so there was still a lot of work to do. While the project is still far from being complete I am happy to say that I’ve made quite some progress. Most importantly, the new design seems to work well and so far I haven’t found any mistakes in the board layout. But let’s go through this step by step.

Have you ever tried to write a program that connects to some device via USB? I have done so a few years ago and was shocked how much of a pain that is (at least on a Windows plattform). I always thought there should be a nice little library that wraps all those uggly DLL imports, marshalling and COM API calls and offers a nice and clean C# interface to the outside world.
