TFT 屏 每一整秒更新顯示
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....
DateTime now=RTC.now();
if (temp_sec!=now.second()){
temp_sec=now.second();
//dot_color=!dot_color;
if (temp_sec%2==0) {
tft.fillRect(80,70,9,9,GREEN);
tft.fillRect(80,90,9,9,GREEN);
Serial.print(temp_sec);
}
else{
tft.fillRect(80,70,9,9,WHITE);
tft.fillRect(80,90,9,9,WHITE);
Serial.print(temp_sec);
}
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
