One down

I spent another half day on one of the two challenges I mentioned yesterday.  While I wasn't able to get the result I wanted, I have come to the conclusion that (within a reasonable amount of effort) it not possible to accomplish what I want.  Specifically, I am dealing with software (a kernel) that is too out of date to take advantage of modern electronics.  While this will eventually lead to different ideas to solve my problem, for now I am falling back to a previous, albeit less optimal, approach.  At end of the day I worked on my other programming problem and while the issue is still unresolved, I am continuing to learn through the process.
