stm32中断使能-新

Sheet1 寄存器相应位置1，中断使能 中断分组优先寄存器设置（AIRCR）只设置一次，只用高4位表示 中断优先寄存器地址 寄存器地址: 0x4000E100 寄存器地址： 0xE000ED00 中断函数名（具体查看stm启动文件） 组 AIRCR[10:8] 分配情况 分配结果 0xE000E400 WWDG_IRQHandler bit:0 WWDG_IRQChannel((u8)0x00)/*WindowWatchDogInterrupt*/ 0 111 .xxxx0000 0位表示 抢占优先级，4位 表示 相应优先级 0xE000E401 PVD_IRQHandler bit:1 PVD_IRQChannel((u8)0x01)/*PVDthroughEXTILinedetectionInterrupt*/ 1 110 y.xxx0000 1位表示  抢占优先级，3位表示  相应优先级 0xE000E402 TAMPER_IRQHandler bit:2 TAMPER_IRQChannel((u8)0x02)/*TamperInterrupt*/ 2 101 yy.xx0000 2为表示  抢占优先级，2位表示  相应优先级 0xE000E403 RTC_IRQHandler bit:3 RTC_IRQChannel((u8)0x03)/*RTCglobalInterrupt*/ 3 100 yyy.x0000 3位表示  抢占优先级，1位表示  相应优先级 0xE000E404 FLASH_IRQHandler bit:4 FLASH_IRQChannel((u8)0x04)/*FLASHglobalInterrupt*/ 4 111 yyyy.0000 4位表示  抢占优先级，0位表示  相应优先级 0xE000E405 RCC_IRQHandler bit:5 RCC_IRQChannel((u8)0x05)/*RCCglobalInterrupt*/ AIRCR设置好后，再设置相应中断优先寄存器 0xE000E406 EXTI0_IRQHandler bit:6 EXTI0_IRQChannel((u8)0x06)/*EXTILine0Interrupt*/ 例如:先选择系统分配情况为yy.xx000(AIRCR=AIRCR|0xA0) 0xE000E407 EXTI1_IRQHandler bit:7 EXTI1_IRQChannel((u8)0x07)/*EXTILine1Interrupt*/ 再设置串口1优先寄存器(具体地址看A列)设置UART1=0x70(0111000)说明串口1设置为1级抢占优先,3级相应优先级 0xE000E408 EXTI2_IRQHandler bit:8 EXTI2_IRQChannel((u8)0x08)/*EXTILine2Interrupt*/ 再设置串口1中断使能寄存器在地址为0x4000E104的bit:5位把该位置1即可 0xE000E409
