Problem air conditioner

[josep112]

Hello The air conditioner uses a raw 199, this has to change the IRremote.h -> #define RAWBUF 100 to 200 and change IRremoteInt.h #define _GAP 5000 change to 50000, the problem is that there are over 300 air and the string only accepts 255 to solve this?

Hi josep112, i can change typedef struct { uint8_t recvpin; // pin for IR data from detector uint8_t rcvstate; // state machine unsigned int timer; // state timer, counts 50uS ticks. unsigned int rawbuf[RAWBUF]; // raw data uint8_t rawlen; // counter of entries in rawbuf } irparams_t;

to typedef struct { uint8_t recvpin; // pin for IR data from detector uint8_t rcvstate; // state machine unsigned long timer; // state timer, counts 50uS ticks. unsigned long rawbuf[RAWBUF]; // raw data long rawlen; // counter of entries in rawbuf } irparams_t; you can change rawbuf to 800 for all AIR (Daikin..). Sketch leaning rawbuf 800 for arduino of Link analysir.com #define LEDPIN 5 #define maxLen 800

volatile unsigned int irBuffer[maxLen]; //stores timings - volatile because changed by ISR volatile unsigned int x = 0; //Pointer thru irBuffer - volatile because changed by ISR

void setup() { Serial.begin(115200); //change BAUD rate as required attachInterrupt(0, rxIR_Interrupt_Handler, CHANGE);//set up ISR for receiving IR signal }

void loop() { // put your main code here, to run repeatedly:

Serial.println(F("Press the button on the remote now - once only")); delay(5000); // pause 5 secs if (x) { //if a signal is captured digitalWrite(LEDPIN, HIGH);//visual indicator that signal received Serial.println(); Serial.print(F("Raw: (")); //dump raw header format - for library Serial.print((x - 1)); Serial.print(F(") ")); detachInterrupt(0);//stop interrupts & capture until finshed here for (int i = 1; i < x; i++) { //now dump the times if (!(i & 0x1)) Serial.print(F("-")); Serial.print(irBuffer[i] - irBuffer[i - 1]); Serial.print(F(", ")); } x = 0; Serial.println(); Serial.println(); digitalWrite(LEDPIN, LOW);//end of visual indicator, for this time attachInterrupt(0, rxIR_Interrupt_Handler, CHANGE);//re-enable ISR for receiving IR signal }

}

void rxIR_Interrupt_Handler() { if (x > maxLen) return; //ignore if irBuffer is already full irBuffer[x++] = micros(); //just continually record the time-stamp of signal transitions

} Sorry for my english thank you

Hi Annhan, Thanks for the reply, I changed the code but did not work my code is below

include

long rawlen; uint8_t RECV_PIN = 2; //an IR detector/demodulatord is connected to GPIO pin 2

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup() { Serial.begin(9600); irrecv.enableIRIn(); // Start the receiver }

void loop() { if (irrecv.decode(&results)) { Serial.println(results.value, HEX); irrecv.resume(); // Receive the next value } delay(100); }

Sorry I had not seen the link, I could change my raw and went from 254 to 347 will test the air thanks for the help

Hi Annhan, Not quite understand what you need, you had said that does not speak in English which his country talves can talk in another language

Hi all.

I've just solved the similar problem. The issue is only with long IR reading. There are good solution with hardware interrupt driving reading: http://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/ It works almost out of the box for ESP8266. Just change this code from 0 to your pin number (I used 12 (D4 on nodemcu aka lolin):

   attachInterrupt(0, rxIR_Interrupt_Handler, CHANGE);//set up ISR for receiving IR signal
   detachInterrupt(0);//stop interrupts & capture until finshed here
   attachInterrupt(0, rxIR_Interrupt_Handler, CHANGE);//re-enable ISR for receiving IR signal

So I've successfully got unsigned int rawData [439] for my Panasonic HVAC.
Than you can use irsend.sendRaw() from this library.

Please safari2 where is the irsend.sendRaw() ? and how to send the obtained code? Thanks

helio58, see link below.

Closing this issue. Versions of the library later than v2.0 now support larger (256+) capture buffers.
