求教：315MHz问题
#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);
}
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！

#include <RCSwitch.h>

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？
int fan_on={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};
for(int i = 0;i<266;i++)
{
if(bWriteLow)digitalWrite(pin, LOW);
else digitalWrite(fan_pin, HIGH);
delayMicroseconds(fan_on);//这里延迟上面取到的微秒数，轮流一高一低一高一低
bWriteLow = !bWriteLow;

如果将发送程序改成这样呢？
#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(266);
// 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);
}
你这个接收端我咋没看到控制灯的代码呢
