我在LED的例程里直接添加EXTI的C和H文件，也按照教程上的来做好相应配置了，但是还是会报错
....Userkeysp_exti.c(27): error: #20: identifier "NVIC_InitTypeDef" is undefined
....Userkeysp_exti.c(30): warning: #223-D: function "NVIC_PriorityGroupConfig" declared implicitly

....Userkeysp_exti.c(67): warning: #223-D: function "EXTI_Init" declared implicitly
都是中断部分的提示没有定义，找不到在哪里出错，求指教！谢谢！ |
