以下是我从 Arduino 读取原始 IR 数据的代码:
#define sprint Serial.print
#define sprintln Serial.println
#include <IRremote.h>
#define IR_RCVR_PIN 11
IRrecv ir_receiver(IR_RCVR_PIN);
decode_results results;
void setup() {
Serial.begin(9600);
ir_receiver.enableIRIn(); // Start the receiver
}
void loop() {
if (ir_receiver.decode(&results)) {
dump(&results);
ir_receiver.resume(); // Receive the next value
}
}
int c = 1;
void dump(decode_results *results) {
int count = results->rawlen;
sprintln(c);
c++;
sprintln("For IR Scope: ");
for (int i = 1; i < count; i++) {
sprint("0x");
sprint((unsigned int)results->rawbuf[i], HEX);
sprint(" ");
}
sprintln("");
sprintln("For Arduino sketch: ");
sprint("unsigned int raw[");
sprint(count, DEC);
sprint("] = {");
for (int i = 1; i < count; i++) {
sprint("0x");
sprint((unsigned int)results->rawbuf[i], HEX);
sprint(",");
}
sprint("};");
sprintln("");
sprint("irsend.sendRaw(raw,");
sprint(count, DEC);
sprint(",38);");
sprintln("");
sprintln("");
}
使用它我可以从遥控器上得到这个:

For IR Scope:
0x47 0x1F 0xB 0x17 0xA 0x17 0xB 0x6 0xA 0x6 0xB 0x6 0xA 0x17 0xB 0x6 0xA 0x6 0xB 0x17

0x6 0xA 0x7 0xA 0x6 0xB 0x6 0xA 0x6 0xB 0x17 0xA 0x6 0xB 0x6 0xA
For Arduino sketch:
unsigned int raw[100] =
{0x47,0x1F,0xB,0x17,0xA,0x17,0xB,0x6,0xA,0x6,0xB,0x6,0xA,0x17,
0xB,0x6,0xA,0x6,0xB,0x17,0xA,0x17,0xA,0x7,0xA,0x17,0xA,0x7,0xA,0x6,
0xB,0x17,0xA,0x17,0xA,0x6,0xB,0x17,0xA,0x17,0xB,0x6,0xA,0x6,0xB,0x17,0xA,
0x6,0xB,0x6,0xA,0x17,0xB,0x6,0xA,0x6,0xB,0x6,0xA,0x7,0xA,0x6,0xB,0x6,0xA,
0x6,0xB,0x6,0xA,0x7,0xA,0x6,0xB,0x6,0xA,0x7,0xA,0x6,0xB,0x6,0xA,0x6,0xB,
0x6,0xA,0x7,0xA,0x6,0xB,0x6,0xA,0x6,0xB,0x17,0xA,0x6,0xB,0x6,0xA,};
因此,在发送此数据时,我可以使用以下指令:
irsend.sendRaw(raw,100,38);
问题是我无法从我需要控制的设备获得任何响应。我已经检查了我的红外发射器,我的读数与上面相同。
我错过了什么吗?
