求教：315MHz问题

xiaoesky

[pre lang="arduino" line="1" file="send_315"]#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

void setup() {

  Serial.begin(9600);
  
  // Transmitter is connected to Arduino Pin #10  
  mySwitch.enableTransmit(10);

  // Optional set pulse length.
  // mySwitch.setPulseLength(320);
  
  // Optional set protocol (default is 1, will work for most outlets)
  // mySwitch.setProtocol(2);
  
  // Optional set number of transmission repetitions.
  // mySwitch.setRepeatTransmit(15);
  
}

void loop() {

  /* Same switch as above, but using decimal code */
  mySwitch.send(13846320, 24);
  delay(5000);  
  mySwitch.send(13846464, 24);  
  delay(5000);  
}[/code]

采用Micro pro arduino + 315MHz收发模块

  mySwitch.send(13846320, 24);
  mySwitch.send(13846464, 24);  
这两段代码中的“13846320”，“13846464”是用例程中的接收程序来获得的。
为何程序写到arduino 中后，执行过程中，通过315MHz发射模块发出信号后，所控制的灯一灭一亮地闪了一下，然后保持了原状态。这是什么问题呢？请教各位高人指点，谢谢！

把接收端的代码放出来看看

使用这个程序，接收到的信号：

风扇开关

Decimal: 13846320 (24Bit) Binary: 110100110100011100110000 Tri-State: 1F01F0F10100 PulseLength: 266 microseconds Protocol: 1
Raw data: 8264,784,268,784,272,260,804,780,276,256,804,260,804,784,268,784,268,260,804,784,272,260,800,264,800,260,804,784,268,784,272,780,272,260,804,256,808,780,272,780,272,260,804,260,804,256,808,256,804,

如何发送这类的信号呢？

发送代码是不是改成这样子呢？

1. int fan_on[266]={8264,784,268,784,272,260,804,780,276,256,804,260,804,784,268,784,268,260,804,784,272,260,800,264,800,260,804,784,268,784,272,780,272,260,804,256,808,780,272,780,272,260,804,260,804,256,808,256,804};
   
2. for(int i = 0;i<266;i++)
   
3.   {
   
4.     if(bWriteLow)digitalWrite(pin, LOW);
   
5.     else digitalWrite(fan_pin, HIGH);
   
6.     delayMicroseconds(fan_on[i]);//这里延迟上面取到的微秒数，轮流一高一低一高一低
   
7.     bWriteLow = !bWriteLow;
   
8.   }

如果将发送程序改成这样呢？

1. #include <RCSwitch.h>
   
2. 
   
3. RCSwitch mySwitch = RCSwitch();
   
4. 
   
5. void setup() {
   
6. 
   
7.   Serial.begin(9600);
   
8. 
   
9.   // Transmitter is connected to Arduino Pin #10  
   
10.   mySwitch.enableTransmit(10);
    
11. 
    
12.   // Optional set pulse length.
    
13. mySwitch.setPulseLength(266);
    
14. 
    
15.   // Optional set protocol (default is 1, will work for most outlets)
    
16.   // mySwitch.setProtocol(2);
    
17. 
    
18.   // Optional set number of transmission repetitions.
    
19.   // mySwitch.setRepeatTransmit(15);
    
20. 
    
21. }
    
22. 
    
23. void loop() {
    
24. 
    
25.   /* Same switch as above, but using decimal code */
    
26.   mySwitch.send(13846320, 24);
    
27.   delay(5000);  
    
28.   mySwitch.send(13846464, 24);  
    
29.   delay(5000);  
    
30. }

你这个接收端我咋没看到控制灯的代码呢
