想用TIM1做一个基本的定时器练习，结果编译不过去，代码如下：
void NVIC_Configuration(void)
{
   NVIC_InitTypeDef NVIC_InitStructure;
   NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
   NVIC_InitStructure.NVIC_IRQChannel =TIM1_UP_IRQHandler;
   NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
   NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
   NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
   NVIC_Init(&NVIC_InitStructure);

}
编译的错误提示为：
user\main.c(132): error:#20: identifier "TIM1_UP_IRQHandler" is undefined
指示TIM1_UP_IRQHandler这个中断未定义，我把它换成TIM1_CC_IRQChannel，结果编译后提示：
user\main.c(133): error: #20: identifier "TIM1_CC_IRQChannel" is undefined
后来发现所有TIM1的中断都不能编译，芯片是F107VC, 请教这是怎么回事？

这个不能乱改的，你要找它的定义才行。

在stm32f10x.h里有定义

是不是弄错了库的版本
或者没有设定好库, 以及包含合适的 .h 文件.
在 2.0 的库 TIM1_UP_IRQHandler 定义在 stm32f10x_nvic.h 里
在 3.0 以上的库. 用 TIM1_UP_IRQn 了, 定义在 stm32f10x.h 里

很抱歉，我没明白2楼的意思，我没有改动任何头文件里的内容，我打开头文件确实看到你列出的这些内容，但不知道你帖出来是为什么。我把整个项目放在附件里，求高手看看，这里先谢了。

我帖出来的是中断向量表。你的程序每次进中断都会查询这个表。

你的NVIC初始化的时候，通道名字要与定义的相同，例如：

  NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);

  NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
