关于stm32启动问题急！希望大家帮帮忙！

下面是在网上找到的资料，大家帮忙看看是不是对的，如果是对的，那复位中断服务程序在哪？我用的启动文件是 startup_stm32f10x_hd.s
STM32的启动文件和启动过程。首先对栈和堆的大小进行定义，并在代码区的起始处建立中断向量表，其第一个表项是栈顶地址，第二个表项是复位中断服务入口地址。然后在复位中断服务程序中跳转C/C++标准实时库的__main函数，完成用户堆栈等的初始化后，跳转.c文件中的main函数开始执行C程序。假设 STM32被设置为从内部FLASH启动（这也是最常见的一种情况），中断向量表起始地位为0x8000000，则栈顶地址存放于0x8000000处，而复位中断服务入口地址存放于0x8000004处。当STM32遇到复位信号后，则从0x80000004处取出复位中断服务入口地址，继而执行复位中断服务程序，然后跳转__main函数，最后进入mian函数，来到C的世界。

以上为中断入口的名字，例如你要写个定时器7的中断程序，那可以这么写：

void TIM7_IRQHandler(void)
{
    //在这输入你的代码

}
