NVIC_InitStructure.NVIC_IRQChannel = EXTI0_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority =0x02;
NVIC_InitStructure.NVIC_IRQChannelSubPriority =0x03;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_Init(&NVIC_InitStructure);
这段代码编译后出现
..HARDWAREEXTIexti.c(80): error: #20: identifier "EXTI0_IRQn" is undefined
神马情况，求大神指教
