IRreciver_cant_get

Other Hardware Sensors

Hi
trying to operate with remote control to switch on blynk.
used that code

#include <IRremote.h>

const int RECV_PIN = 7;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup(){
  Serial.begin(9600);
  irrecv.enableIRIn();
  irrecv.blink13(true);
}

void loop(){
  if (irrecv.decode(&results)){
        Serial.println(results.value, HEX);
        irrecv.resume();
  }
}

but when it comes to pressing any button I get FFFFFFFF code whatever button I press no matter how long either one time either for couple secs. Don't understand why can't I get normal code of each button?

Please help
Thanks so far.

I have moved your topic to Sensors....I don't think the topic was relevant to Emergency Response: Remote Learning.

Can you please give this demo sketch ago?

#include <IRremote.hpp> // include the library

void setup() {
    Serial.begin(115200);

    // Start the receiver and if not 3. parameter specified, take LED_BUILTIN pin from the internal boards definition as default feedback LED
    IrReceiver.begin(2, ENABLE_LED_FEEDBACK);

    Serial.print(F("Ready to receive IR signals of protocols: "));
    printActiveIRProtocols(&Serial);
    Serial.println(F("at pin " STR(IR_RECEIVE_PIN)));
}

void loop() {
    /*
     * Check if received data is available and if yes, try to decode it.
     * Decoded result is in the IrReceiver.decodedIRData structure.
     *
     * E.g. command is in IrReceiver.decodedIRData.command
     * address is in command is in IrReceiver.decodedIRData.address
     * and up to 32 bit raw data in IrReceiver.decodedIRData.decodedRawData
     */
    if (IrReceiver.decode()) {

        /*
         * Print a short summary of received data
         */
        IrReceiver.printIRResultShort(&Serial);
        IrReceiver.printIRSendUsage(&Serial);
        if (IrReceiver.decodedIRData.protocol == UNKNOWN) {
            Serial.println(F("Received noise or an unknown (or not yet enabled) protocol"));
            // We have an unknown protocol here, print more info
            IrReceiver.printIRResultRawFormatted(&Serial, true);
        }
        Serial.println();

        /*
         * !!!Important!!! Enable receiving of the next value,
         * since receiving has stopped after the end of the current received data packet.
         */
        IrReceiver.resume(); // Enable receiving of the next value

        /*
         * Finally, check the received data and perform actions according to the received command
         */
        if (IrReceiver.decodedIRData.command == 0x10) {
            // do something
        } else if (IrReceiver.decodedIRData.command == 0x11) {
            // do something else
        }
    }
}

Your code work OK @ simulator.
