现象

卡西欧太空人表盘显示时间

注意

问题：增加上时间显示的时候，明显感觉到屏幕右半边有闪烁
分析方法：在显示前后打上log，然后通过串口监视器查看log，发现显示图片前后时间差为0.047s.
我们常见的视频需要24帧，即每张图的间隔时间不能超过0.417s，否则人会感知到。
所以出现了闪烁。

display.clear();Serial.println("start pict");display_bmp_watch();Serial.println("end pict");display_time();display_weather();display.display();

在这里插入图片描述

原因：
这是因为我在display_bmp_watch()中增加了display.display();
将其删除，然后在所有数据都打印好后再显示。

void display_bmp_watch(){
    
// display.clear();drawImageDemo_64_64_w(watch_image_current);display.display();
}void pattern_solution1()
{
      display.clear();		//清空Serial.println("start pict");display_bmp_watch();Serial.println("end pict");display_time();display_weather();display.display();	//显示delay(100);
}
