The minimal (kernel) example uses a kernel timer, that is usually not a good timing source at all. The userspace example uses the setitimer() function to generate SIG_ALRM signals, which has the same behaviour. These two examples use on-board methods go create cyclic-tasks to get something running without great efford. They're not meant to create jitter-free cycles. Do you have the possibility to try RTAI or an RT-preempt kernel? -- Best regards, Florian Pose http://etherlab.org _______________________________________________ etherlab-users mailing list [email protected] http://lists.etherlab.org/mailman/listinfo/etherlab-users
