I'll give a few hints to the *coding*, not the rt-patch series itself: For a general guide to the coding, I'd say have a look at http://rt.wiki.kernel.org/index.php/HOWTO:_Build_an_RT-application Also, look into - mutex/semaphores - threads - message queues have a look at https://computing.llnl.gov/tutorials/pthreads/ If your system becomes very large (and you have very formal requirements) perhaps you should look into using Ada? Good luck with the project - share some photos/videos of the aircraft in action! :-) -- mvh Henrik Austad
