初衷是控制步进电机旋转方向和速度，但12864的显示不正常，

2019-07-15 18:49发布

简单介绍下，我的初衷是控制步进电机旋转方向和速度，并以12864显示

设计中有四个按钮开关，从上到下依次是：控制旋转的开关；控制方向的开关；增加速度的按钮；减少速度的按钮。我遇到的问题是：1、点击“增速按钮"和”减速按钮“时，12864显示屏都会出现故障。但如果把sp（speed）从中断程序中放到main函数里，就不会出现显示故障。请问sp（speed）放到中断程序中，哪里出了问题？怎么改？（注：sp（int i）作用是当按下加减速按钮时，12864的显示不同的速度等级）

2、proteus 仿真遇到这个问题，怎么解决？

我发现第2个问题和main函数一开始的这一段有关： LCDMcs=1; //右屏开显示 LCDScs=0; hz_LCDDisp16(4,0,hz_ji); LCDMcs=0; //左屏开显示 LCDScs=1; hz_LCDDisp16(0,0,hz_zhuang); hz_LCDDisp16(0,16,hz_tai); hz_LCDDisp16(0,32,hz_maohao); hz_LCDDisp16(2,0,hz_fang); hz_LCDDisp16(2,16,hz_xiang); hz_LCDDisp16(2,32,hz_maohao); hz_LCDDisp16(4,0,hz_su); hz_LCDDisp16(4,16,hz_du); hz_LCDDisp16(4,32,hz_maohao); hz_LCDDisp16(4,48,s1);
