Hi As we have already talked on xenomai-help, I've done a first example with rtdm. It's very simple and the goal is just to show how to register and use a rtdm device. This is the first release, so it isn't perfect (comments and feedback welcome). If this example is good enough, I have to plane next one. I think about shawdow_task (to use device in rt mode) and synchronization. If people have idea for others example, I would be pleased to read them. regards, trem
