/*****中断服务程序*****/
void intersvr0(void) interrupt 0 { KY=~KY; //每个摇动来回水银开关会在摆幅两端分别产生下降沿中断，只提取其中一次（从左向右摇才显示） if(KY==0) { num++; //计算中断次数 switch(pic) //选择画面 { case 0:{display1_ltor();}break; case 1:{display2_ltor();}break; case 2:{display3();}break; case 3:{display4();}break; default:{display1_ltor();} } } } 上面是中断程序 控制变量ky初值为0，摇摇棒从左往右或者从右往左都会产生一个中断，按照程序所描述是不是说 第一次中断不送数据，第二次中断送数据，第3次又送。。。。。 那这样来分析的话摇摇棒有可能从左往右的时候送数据，也有可能从右往左的时候送数据， 但是实际上之后摇摇棒从左往右时才送数据啊， 有点搞不懂 哪位大神能看看我的分析哪里出了问题，感激不尽！！！

在这里，我只能祝愿楼主早日能找到这个问题的解决办法了，另外还是想问一下楼主，你所说的“摇摇棒”是不是演唱会里观众手中挥舞的发光棒么？  补充：刚才必应一下，原来是这个，关键部件是水银开关，回到题目，在这里，设A为左边，B为右边，因为摇摇棒在摇晃的时候，路径是一个扇形，即A与B的路径也是一个扇形，在摇摇棒摇摆的时候，在A点位置首先程序会将变量KY设置为1，然后调用中断显示画面，那个变量pic用来设置显示哪一幅画面，在摇摆到B点位置时程序将变量KY设置为0，然后调用中断，显然无法显示画面，至于程序如何知道摇摇棒在A点还是B点，关键还是水银开关。 |

我现在的理解是KY初值为0，在A点触发中断，执行KY=~KY,取反之后为1，调用不了显示程序。 看你的解释是说在触发中断之前还有个让ky由0变1的操作吗 |

那个KEY变量绑定到P3_7引脚，这个变量比较重要，P3_7引脚的高低电平会改变KEY的值，KEY=0调用中断，KEY=1不调用中断，至于ZD的值只是用于判断是否显示画面，这个没有什么好深究的，主要还是KEY。 |

晓晓江南 发表于 2017-6-1 21:42 sorry 发的这个程序和我刚开始给的变量名有点不一样，原来那个KY是下面这个程序的ZD。。 p3.7引脚电平变化不会触发中断，水银开关是连p3.2（into） |
