Panasonic projector IR Remote decoding

Other Hardware Sensors
1

Hi everyone!

I am making an art project which involves reverse engineering of a Panasonic projector IR Remote and sending the decoded signal back to the projector.

I made a simple decoder and I use IR.Remote Recieve Demo for it.

It works well with NEC remotes and any other remote I could get my hands on but the Panasonic remote, code for which I so desperately need because the deadline is near, makes the sketch behave weird - it tends to return the same result for any button pressed (and that result once sent to the projector does nothing) and also makes the reciever sketch go into the endless loop of returning that same result over and over again every fraction of a second until the Arduino is turned off. And it happens after pressing any Panasonic remote button only once. No other remote does that to it. I tried to recieve and send raw data, change pins, etc. to no avail. But as it is the only projector I can use for many reasons I need to solve this ASAP.

Any help would be really appreciated!

Thank you!

Volodymyr

How many bytes are you getting from the Panasonic remote! Can you provide us with a sample?

And the code you are using…

Yes, sure, here you go! Here's the data example

Protocol=PANASONIC Data=0x4011200 Address=0x4004 (48 bits)
rawData[101]: -2020600 3550 -1700 500 -400 450 -1250 500 -400 500 -350 500 -400 500 -350 500 -400 500 -400 500 -400 450 -400 500 -400 450 -400 500 -400 500 -1250 450 -400 500 -400 500 -350 500 -400 500 -350 500 -400 500 -400 450 -400 500 -350 550 -1250 500 -350 500 -400 500 -350 500 -1250 500 -400 550 -350 450 -1300 450 -400 500 -400 450 -400 500 -400 450 -400 500 -400 500 -350 500 -400 500 -400 500 -1250 450 -400 500 -1250 500 -1250 500 -1250 500 -350 500 -1300 450 -400 500 -1250

The code I use is from IRRemote library (v.2.8) examples called IRrecieveDemo

#include <IRremote.h>

#if defined(ESP32)
int IR_RECEIVE_PIN = 15;
#elif defined(ARDUINO_AVR_PROMICRO)
int IR_RECEIVE_PIN = 10;
#else
int IR_RECEIVE_PIN = 11;
#endif
IRrecv IrReceiver(IR_RECEIVE_PIN);

// On the Zero and others we switch explicitly to SerialUSB
#if defined(ARDUINO_ARCH_SAMD)
#define Serial SerialUSB
#endif

void setup() {
    pinMode(LED_BUILTIN, OUTPUT);

    Serial.begin(115200);
#if defined(__AVR_ATmega32U4__) || defined(SERIAL_USB) || defined(SERIAL_PORT_USBVIRTUAL)
    delay(2000); // To be able to connect Serial monitor after reset and before first printout
#endif
    // Just to know which program is running on my Arduino
    Serial.println(F("START " __FILE__ " from " __DATE__));

    // In case the interrupt driver crashes on setup, give a clue
    // to the user what's going on.
    Serial.println("Enabling IRin");
    IrReceiver.enableIRIn();  // Start the receiver
    IrReceiver.blink13(true); // Enable feedback LED

    Serial.print(F("Ready to receive IR signals at pin "));
    Serial.println(IR_RECEIVE_PIN);
}

void loop() {
    if (IrReceiver.decode()) {
        IrReceiver.printResultShort(&Serial);
        Serial.println();

        IrReceiver.resume(); // Receive the next value
    }
    delay(100);
}

Why do you use an acient version of the lib?

5

Mostly because the sketch I use for sending uses the same version

UPD: I could not make it work with this library but managed to make it work with VEGA_IRremote library instead
