I need a Remote Control, but the Arduino only supports 32 bits. And the Panasonic is 48 bits.

CODE BELOW

```arduino
    // INCLUINDO A BIBLIOTECA IRREMOTE
    #include <IRremote.h>

    // CHAMANDO O OBJETO
    IRsend irsend;

    // SETUP
    void setup() {
      Serial.begin(9600); // Inicializa a Serial
    }

    void loop() {
      // CONTROLA A TV SE TIVER DADOS NO SERIAL
      if (Serial.available() > 0) {
        controlarTV();
      }
    }

    // ENVIA OS DADOS
    void enviarDados(unsigned long hexControl) {
      irsend.sendPanasonic(hexControl, 48); // Envia o código IR usando o protocolo NEC
      delay(1000); // Espera 1 segundo entre envios
    }

    // FUNÇÃO PARA CONTROLAR A TV
    void controlarTV() {
      char tecla = Serial.read(); // Captura o Serial para a Variavel Tecla

      // CONDICIONAL PARA CONTROLAR A TV
      switch (tecla) {
        
        // LIGAR E DESLIGAR
        case 'P':
          enviarDados(0x20DF10EF);
          break;
        
        // NÚMEROS DE 0 A 9
        case '0':
          enviarDados(0x20DF08F7);
          break;
        case '1':
          enviarDados(0x20DF8877);
          break;
        case '2':
          enviarDados(0x20DF48B7);
          break;
        case '3':
          enviarDados(0x20DFC837);
          break;
        case '4':
          enviarDados(0x20DF28D7);
          break;
        case '5':
          enviarDados(0x20DFA857);
          break;
        case '6':
          enviarDados(0x20DF6897);
          break;
        case '7':
          enviarDados(0x20DFE817);
          break;
        case '8':
          enviarDados(0x20DF18E7);
          break;
        case '9':
          enviarDados(0x20DF9867);
          break;

        // VOLUME
        case '+':
          enviarDados(0x20DF40BF);
          break;
        case '-':
          enviarDados(0x20DFC03F);
          break;

        // CANAL +
        case 'W':
          enviarDados(0x20DF00FF);
          break;

        // CANAL -
        case 'S':
          enviarDados(0x20DF807F);
          break;

        // MUTE`your text`
        case 'M':
          enviarDados(0x20DF906F);
          break;
      }
    }

I use a BigNumber Library, but no success.

Looking at [https://github.com/Arduino-IRremote/Arduino-IRremote](https://github.com/Arduino-IRremote/Arduino-IRremote)  
Version 4 of the IR library supports up to 64 bit data

Welcome to the forum

As your topic does not relate directly to the installation or operation of the IDE it has been moved to the Programming Questions category of the forum
