求助,我用mega2560作接收端,uno作发射端,也是用这个315模块通讯
接收端代码用的是RCSwitch库的ReceiveDemo_Simple,如下:
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
void setup() {
Serial.begin(9600);
mySwitch.enableReceive(0); // Receiver on inerrupt 0 => that is pin #2
}
void loop() {
if (mySwitch.available()) {
int value = mySwitch.getReceivedValue();
if (value == 0) {
Serial.print("Unknown encoding");
} else {
Serial.print("Received ");
Serial.print( mySwitch.getReceivedValue() );
Serial.print(" / ");
Serial.print( mySwitch.getReceivedBitlength() );
Serial.print("bit ");
Serial.print("Protocol: ");
Serial.println( mySwitch.getReceivedProtocol() );
}
mySwitch.resetAvailable();
}
}
发射端代码用的是RCSwitch库的SendDemo,如下:
#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() {
/* See Example: TypeA_WithDIPSwitches */
mySwitch.switchOn("11111", "00010");
delay(1000);
mySwitch.switchOn("11111", "00010");
delay(1000);
/* Same switch as above, but using decimal code */
mySwitch.send(5393, 24);
delay(1000);
mySwitch.send(5396, 24);
delay(1000);
/* Same switch as above, but using binary code */
mySwitch.send("000000000001010100010001");
delay(1000);
mySwitch.send("000000000001010100010100");
delay(1000);
/* Same switch as above, but tri-state code */
mySwitch.sendTriState("00000FFF0F0F");
delay(1000);
mySwitch.sendTriState("00000FFF0FF0");
delay(1000);
delay(20000);
}
接收端收不到数据,求大神解答 |
