前一段时间都没怎么学F1开发板，这段时间又从新开始学习F1的库，写到外部中断这发现了小问题，我用的另外一个ZET6的核心板写的外部中断，写进去发现只有WK_UP按键按下有效，我看了下程序后发现我的两个按键全部没有把GPIO和中断线映射在一起，但是为什么GPIOA0是有效的，我想可能是因为EXTICR1开机默认中断线0默认在PA0口，然后我就把两个按键IO口和中断线映射好，改了下    GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource2);函数把A映射到中断线2上，程序下进去另一个按键有效了，但是为什么WK_UP按键按下还是有效的，- -我试了下把原子外部中断历程改了吓到战舰V1中发现也是这样的，求解[mw_shl_code=c,true]void EXTI_Init_Config(void)

我代码中吧WK_UP设置在GPIO_PinSource2，按理说按下WK_UP键应该不会有效的
