TFT 屏 每一整秒更新顯示

dicklaw795

arduino mini pro + ds1307

想做的是屏上顯示 "時:分",時分中間兩點每一整秒閃一次,應該不難,但搞了兩整天仍沒搞好....

1. DateTime now=RTC.now();
   
2. if (temp_sec!=now.second()){
   
3.     temp_sec=now.second();
   
4.     //dot_color=!dot_color;
   
5.     if (temp_sec%2==0) {
   
6.       tft.fillRect(80,70,9,9,GREEN);
   
7.       tft.fillRect(80,90,9,9,GREEN);
   
8.       Serial.print(temp_sec);
   
9.     }
   
10.     else{
    
11. 
    
12.       tft.fillRect(80,70,9,9,WHITE);
    
13.       tft.fillRect(80,90,9,9,WHITE);
    
14.       Serial.print(temp_sec);
    
15.     }

复制代码

if temp_sec 不等 now.second
temp_sec=now.second
if temp_sec除2餘數=0 兩點綠色 否 則兩點白色

就只這樣,那兩點就是不閃,所以加了句 serial.print(temp_sec)測試,發現在serial運行正常,

再試... if (temp_sec%3==0) { ...那兩點會閃了.但是每兩秒閃一次!

最後發現不加每秒執行,順loop而行是沒問題,加了if (temp_sec!=now.second()){就出事

求大大高人打救
