我正在做我最后一年的项目,但我遇到了一个找不到答案的问题。我尝试解码空调的红外信号。我已经使用 Arduino 和 Raspberry PI (LIRC) 解码了 raw 和 hex,但是当我发送信号时我的空调没有打开。AC 品牌是 Acson。我在做什么我认为这是正确的,因为当我发送解码信号时我的电视会打开和关闭。我还尝试以不同的频率(36 kHz、38、40、433 ......)发送原始代码。他们似乎都没有工作。请帮我......
这些是打开/关闭按钮的原始代码(它们每次都在变化):

这是我用于解码部分的代码:
int RECV_PIN = 2;
IRrecv irrecv(RECV_PIN);
decode_results results;
//#define RAWBUF 255
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
}
// Dumps out the decode_results structure.
// Call this after IRrecv::decode()
// void * to work around compiler issue
//void dump(void *v) {
// decode_results *results = (decode_results *)v
void dump(decode_results *results) {
int count = results->rawlen;
if (results->decode_type == UNKNOWN) {
Serial.print("Unknown encoding: ");
}
else if (results->decode_type == NEC) {
Serial.print("Decoded NEC: ");
}
else if (results->decode_type == SONY) {
Serial.print("Decoded SONY: ");
}
else if (results->decode_type == RC5) {
Serial.print("Decoded RC5: ");
}
else if (results->decode_type == RC6) {
Serial.print("Decoded RC6: ");
}
else if (results->decode_type == PANASONIC) {
Serial.print("Decoded PANASONIC - Address: ");
Serial.print(" Value: ");
}
else if (results->decode_type == JVC) {
Serial.print("Decoded JVC: ");
}
Serial.print(results->value, HEX);
Serial.print(" (");
Serial.print(results->bits, DEC);
Serial.println(" bits)");
Serial.print("Raw (");
Serial.print(count, DEC);
Serial.print("): ");
for (int i = 0; i < count; i++) {
if ((i % 2) == 1) {
Serial.print(results->rawbuf[i]*USECPERTICK, DEC);
}
else {
Serial.print(-(int)results->rawbuf[i]*USECPERTICK, DEC);
}
Serial.print(" ");
}
Serial.println("");
}
void loop() {
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX);
dump(&results);
irrecv.resume(); // Receive the next value
}
}
而这个用于向 AC 发送原始信号:
void setup()
{
Serial.begin(9600);
}
void loop() {
for (int i = 0; i < 1000; i++)
{
// send variable sonyPower in length 31 at 40 Khz
irsend.sendRaw(turnOff,131,433);
delay(3000);
}
}
更新
我使用 IrLib 获得了此信息...
