You missed all the directives that use ticks in the Classic API. There is rtems_task_wake_after for one. Almost every service that had a delay or timeout is in ticks. The length of a tick is configurable in microseconds.
POSIX has different services and specifies time intervals and delays differently. See clock_nanosleep for an example where you can even pick the clock source. --joel On Thu, Dec 24, 2020, 5:13 AM Karel Gardas <karel.gar...@centrum.cz> wrote: > > I'd try to use POSIX API and POSIX timers.
