great to have someone to share experiences. I know that it won’t be a real-time OS, but I am trying to find the DotNet components that make it as “real-timish” as possible. Maybe I described it too complicated, but the only difference between our ideas seems to be, that I want to use a timer-triggered WaitOne instead the Sleep to pause the measurement thread. The rest is planned to be similar. Based on our experiences, maybe we could suggest some easy-to-use-classes for the project afterwards.
