Question

我有一个奇怪的问题：o 我在两个xbee之间建立连接，当我点击一个按钮连接到引脚13灯亮，然后xbee协调器发送信息以打开连接到xbee路由器的引脚D3的LED。问题是，当我点击按钮时有时不开启LED开关。我不知道问题出在代码中，或者只是一个连接问题

＆＃13;

int led = 13;
const int bouton = 2;
boolean state;
boolean laststate; 
void setup() {
  // put your setup code here, to run once:
pinMode(led, OUTPUT);
Serial.begin(9600);
pinMode(bouton, INPUT);
  digitalWrite(led, LOW);


}
void loop() {
  // put your main code here, to run repeatedly:
 state = digitalRead(bouton);
  digitalWrite(led, state);
  if (state == HIGH) {
    Serial.println("on");
    setRemoteState(5);
    delay(5000);
  } else {
    Serial.println("off");
    setRemoteState(4);
    delay(5000);

  }
}  

void setRemoteState(char value){
  Serial.write(0x7E); // start byte
  Serial.write((byte)0x0);
  Serial.write(0x10);
  Serial.write(0x17);
  Serial.write((byte)0x0);
  // id of recipient or use 0xFFFF for broadcast
  Serial.write((byte)00);
  Serial.write((byte)00);
  Serial.write((byte)00);
  Serial.write((byte)00);
  Serial.write((byte)00);
  Serial.write((byte)00);
  Serial.write(0xFF);
  Serial.write(0xFF);
  // 16 bit of reciepent 
  Serial.write(0xFF);
  Serial.write(0xFE);  
  
   Serial.write(0x02); 
   
   Serial.write('D');
   Serial.write('2');
   
   Serial.write(value);
   
   long sum = 0x17 + 0xFF + 0xFF + 0xFF + 0xFE + 0x02 + 'D' + '2' + value;
   Serial.write(0xFF - ( sum & 0xFF) );
   Serial.println(sum,HEX);
}

Answer 1

看起来问题在于延迟（5000）微控制器将在按钮状态的样本之间等待5秒。如果你删除延迟声明，它应该立即打开和关闭。

你应该尝试仅在状态改变时触发setRemoteState，因此它不会不断发送它。

之类的东西

$body = @{
    project_id = $project_id
    task_token = $task_token
}

$action = {Invoke-RestMethod -Uri http://localhost/temp.php -Method Post -Body $body}

Register-ObjectEvent -InputObject $timer -EventName Elapsed -SourceIdentifier MyTimer -Action $action

我想到像这样的剧本！

String inputString;
int led = 13;
boolean state;
boolean laststate; 
void setup() {
  // put your setup code here, to run once:
pinMode(led, OUTPUT);
Serial.begin(9600);
Serial1.begin(9600);

}
void loop() {
while (Serial.available() ) {
    // get the new byte:
    delay(3);  
    char inChar = Serial.read();
    // add it to the inputString:
    inputString += inChar;
    }
  if (inputString.length() >0) {
    Serial.println(inputString);
if (inputString == "on"){
 digitalWrite(led,HIGH);
  setRemoteState(5);

}

if (inputString == "off"){
 digitalWrite(led,LOW);
setRemoteState(4);

}
inputString=""; 
}
}

void setRemoteState(char value){
  Serial1.write(0x7E); // start byte
  Serial1.write((byte)0x0);
  Serial1.write(0x10);
  Serial1.write(0x17);
  Serial1.write((byte)0x0);
  // id of recipient or use 0xFFFF for broadcast
  Serial1.write((byte)00);
  Serial1.write((byte)00);
  Serial1.write((byte)00);
  Serial1.write((byte)00);
  Serial1.write((byte)00);
  Serial1.write((byte)00);
  Serial1.write(0xFF);
  Serial1.write(0xFF);
  // 16 bit of reciepent 
  Serial1.write(0xFF);
  Serial1.write(0xFE);  
  
   Serial1.write(0x02); 
   
   Serial1.write('D');
   Serial1.write('2');
   
   Serial1.write(value);
   
   long sum = 0x17 + 0xFF + 0xFF + 0xFF + 0xFE + 0x02 + 'D' + '2' + value;
   Serial1.write(0xFF - ( sum & 0xFF) );
   Serial1.print(sum,HEX);
}
