Periodic task implementation

[lucazanesco]

Hello, here's Luca, I'm a computer science student. I'm trying to implement periodic tasks using zephyr on my NUCLEO board. Do you have any advice for implementing it? Actually I've tried with sys_clock_nanosleep() and with ksleep() using K_TIMEOUT_ABS_MS for absolute timing. What I'm trying to do is to implement a thread A that runs each 10ms and a thread B that runs each 20ms. Thanks for help

using event in task

#define EVT_500HZ BIT(0)
#define EVT_200HZ BIT(1)
#define EVT_100HZ BIT(2)
#define EVT_50HZ BIT(3)
#define EVT_10HZ BIT(4)
#define EVT_1HZ BIT(5)
/* timer tiger event */
while (1) {
        if (events = k_event_wait(&worker_event,
				 EVT_500HZ | EVT_200HZ |
				 EVT_100HZ | EVT_50HZ | EVT_10HZ,
				 false, K_FOREVER)) {
	if (events & EVT_200HZ) {
		event_period_exec(EVENT_PERIOD_5MS);
	}

	if (events & EVT_100HZ) {
		event_period_exec(EVENT_PERIOD_10MS);
	}

	if (events & EVT_50HZ) {
		event_period_exec(EVENT_PERIOD_20MS);
	}

	if (events & EVT_10HZ) {
		event_period_exec(EVENT_PERIOD_100MS);
	}

	if (events & EVT_1HZ) {
		event_period_exec(EVENT_PERIOD_1000MS);
	}
}

Okay thanks. Do you think this is the native zephyr method that allows periodic tasks? what do you think about the methods that i tried?
