mbed rtos定时器的工作原理

写个代码验证下：

#include "mbed.h"
#include "rtos.h"

DigitalOut led1(PTB7);
DigitalOut led2(PTB6);
DigitalOut led3(PTB5);
DigitalOut led4(PTB4);

DigitalOut LEDs[4] =
{
	led1, led2, led3, led4
};

void blink(void const *n)
{
	LEDs[(int)n] = !LEDs[(int)n];
}

int main(void)
{
	RtosTimer led_1_timer(blink, osTimerPeriodic, (void *)0);
	RtosTimer led_2_timer(blink, osTimerPeriodic, (void *)1);
	RtosTimer led_3_timer(blink, osTimerPeriodic, (void *)2);
	RtosTimer led_4_timer(blink, osTimerPeriodic, (void *)3);

	led_1_timer.start(2000);
	led_2_timer.start(1000);
	led_3_timer.start(500);
	led_4_timer.start(250);

	Thread::wait(osWaitForever);
}
