Question

“我正在尝试制作一个程序，我通过一个按钮控制了6种模式，问题是在SOS例程之后，例程会一直持续，并且不符合按钮按下直到除非我时间与SOS的最后一个S完全吻合。下面是程序，请解释如何只需按一下按钮即可退出例行程序。

其次可以将此程序转换为.hexfile吗？对于PIC12微控制器？问候， Fawad“

// Uses button presses to switch an LED between off, dim, medium, high brightness & SOS.

更频繁地使用digitalRead。

在每个＆＃34; SOS＆＃34;的中间和末尾添加一个验证例程的按钮。字母以清除ledMode。

像：

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(dit);                // wait
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(blankTime);          // wait
  if (digitalRead(buttonPin) == HIGH) //READ
  {     delay(100);                   //DELAY
  ledMode = ledMode + 0;              //CLEAR
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(dit);                // wait
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(blankTime);          // wait  
  if (digitalRead(buttonPin) == HIGH) //READ
  {     delay(100);                   //DELAY
  ledMode = ledMode + 0;              //CLEAR      
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(dit);                // wait
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(blankTime);          // wait
  if (digitalRead(buttonPin) == HIGH) //READ
  {     delay(100);                   //DELAY
  ledMode = ledMode + 0;              //CLEAR
