OV5116摄像头求解

qq342653239

求教原子哥
最近在弄OV5116摄像头
在主函数开启场中断（外部中断线3），然后进入场中断后，先把场中断关掉，然后再在场中断里面开行中断（外部中断线1），结果在行中断设断点全速运行调试发现进不去行中断，场中断可以进去，两个的配置是一样的，只是优先级不同而已，但是我都把场中断关了啊？？ 求解

void EXTI3_IRQHandler(void)

{

if(EXTI_GetITStatus(EXTI_Line3) != RESET) //确保是否产生了EXTI Line中断

{

EXTI_ClearITPendingBit(EXTI_Line3);     //清除中断标志位

DISABLE_VS();

EXTI_ClearITPendingBit(EXTI_Line1);     //清除中断标志位

ENABLE_HS();

// EXTI->IMR|=1<<1;//  开启line BITx上的中断

//  EXTI->EMR|=1<<1;//  开启line BITx上的事件触发 (如果不屏蔽这句,在硬件上是可以的,但是在软件仿真的时候无法进入中断!)

   //DISABLE_VS();

    c_lie=0;

lie_count=0;

image_show(50,50+hang_end,50,50+lie,image);

---------------------------------
看错，不好意思。
眼花了...
你的配置看起来没问题哦，单独测试下中断试试吧。

qq342653239

照理说我退出场中断之后，即使优先级错了的话也应该能进入行中断，我只开启一次场中断，第二次场中断是在行中断里的一个读完图像后才再次开启的，不会有有影响吧。但是就是进不去行中断，好纳闷

怎么你把两个中断都接在一个中断线上啊？

不是Line1 和 Line3吗？ 场中断是3 行中断是1
