STM32学习笔记—SysTick定时器

e the SysTick Counter 允许SysTick计数器*/

SysTick_CounterCmd(SysTick_Counter_Enable);

TimingDelay = nTime;

while(TimingDelay != 0)

; //等待计数至0

/* Disable the SysTick Counter 禁止SysTick计数器*/

SysTick_CounterCmd(SysTick_Counter_Disable);

/* Clear the SysTick Counter 清零SysTick计数器*/

SysTick_CounterCmd(SysTick_Counter_Clear);

}

中断函数，定时器减至零时调用，放在stm32f10x_it.c文件中
