如何停止循环的Arduino [英] how to stop a loop arduino

问题描述

我有这样的循环，我将如何结束循环？

 无效循环（）{
      //读取按钮输入引脚：       一个++;
      Serial.println（一）;
        analogWrite（speakerOut，NULL）;      如果（一个大于50＆放大器;＆放大器;一个与所述; 300）{
      analogWrite（speakerOut，200）;
      }      如果（A＆LT; = 49）{
        analogWrite（speakerOut，NULL）;
      }      如果（一个或GT; = 300＆放大器;＆放大器;一个与所述; = 2499）{
          analogWrite（speakerOut，NULL）;
      }
 

解决方案

Arduino的具体规定绝对没有办法退出的循环功能，展出由code实际运行的：

 设置（）;为（;;）{
    循环（）;
    如果（serialEventRun）serialEventRun（）;
}
 

此外，在微控制器上有没有什么退出到摆在首位。

你能做的最接近的是刚刚暂停处理器。直到它的复位，将停止处理。

I have this loop, how would I end the loop?

 void loop() {
      // read the pushbutton input pin:

       a ++;
      Serial.println(a);
        analogWrite(speakerOut, NULL);

      if(a > 50 && a < 300){
      analogWrite(speakerOut, 200);
      }

      if(a <= 49){
        analogWrite(speakerOut, NULL);
      }

      if(a >= 300 && a <= 2499){
          analogWrite(speakerOut, NULL);
      }

解决方案

Arduino specifically provides absolutely no way to exit their loop function, as exhibited by the code that actually runs it:

setup();

for (;;) {
    loop();
    if (serialEventRun) serialEventRun();
}

Besides, on a microcontroller there isn't anything to exit to in the first place.

The closest you can do is to just halt the processor. That will stop processing until it's reset.
