+ * @c last_wakeup should be set to ztimer_now(@p ztimer) before first call of the
+ * function.
+ * If the time (@p last_wakeup + @p period) has already passed, the function
+ * sets @p last_wakeup to @p last_wakeup + @p period and returns immediately.
+ * @param[in] ztimer ztimer clock to operate on
+ * @param[in] last_wakeup base time stamp for the wakeup
+ * @param[in] period time in ticks that will be added to @p last_wakeup
+void ztimer_periodic_wakeup(ztimer_dev_t *ztimer, uint32_t *last_wakeup,
+ uint32_t period);
+ * @brief Put the calling thread to sleep for the specified number of ticks
I bet that this is impossible, as e.g. a thread with higher priority might get the CPU at the very moment the caller wants to wake up. As far as I know, RIOT never had the goal to provide **hard** real time features, but **soft** real time features instead.
