【NB-IoT模块显示屏逻辑显示】

• 一、最终按键控制文字滚动效果：
  
• 二、实验要求：
  
• 三、实现部分代码剖析：
  
• 
  
  
  
  • 1、对需要显示的汉字按要求进行取模并加入字库中
    
  • 2、初始化OLED外设
    
  • 3、进行按钮事件监听
    
  • 4、对Key2进行算法搭建
    
  • 5、Key3和Key4可以根据Key2的逻辑直接套娃就行
    
    
  
• 三、实现总结：
  
• 三、实验源码：[NB-IoT显示屏逻辑显示](https://download.caogenba.net/download/a6662580/75827632)
  

• 从上到下循环滚动时，需要将汉字旋转90度
  
• 把数据添加到字库中，并做好注释

• 添加了横屏和竖屏的汉字，并添加一个空白的汉字擦除汉字；
  

//初始化部分外设
  OLED_Init();
  OLED_Clear();
复制代码

KeyDownHandler();  //进行按钮事件监听
