SysTick_IRQn

SysTick_IRQn是一个用于处理系统滴答定时器（SysTick）中断的中断号。在提供的引用中，它被用于启用SysTick中断。在main()函数中调用NVIC_EnableIRQ(SysTick_IRQn)会导致硬件错误（HardFault）发生。然而，如果移除对NVIC_EnableIRQ(...)的调用，即只调用SysTick_Config(SystemCoreClock * SYSTICK_INT_FREQ)，则不会出现硬件错误。SysTick_IRQn也在裸机代码中被使用，在HAL_InitTick函数中，用于配置SysTick中断的优先级。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
