serialEvent()

Descripción

Se llama cuando se dispone de datos. Utilice Serial.read(), Serial.readBytes(), Serial.readBytesUntil(), Serial.readString(), or Serial.readStringUntil() para capturar estos datos.

Sintaxis

void serialEvent() { //instrucciones }

Solo Arduino Mega:

void serialEvent1() { //instrucciones } void serialEvent2() { //instrucciones } void serialEvent3() { //instrucciones }

Parámetros

  • instrucciones: cualquier instrucción válida.

Ejemplo

void setup() { Serial.begin(9600); } void loop() { } void serialEvent() { int incomingByte = Serial.read(); // prints the received data Serial.print("I received: "); Serial.println((char)incomingByte); }
  • Compile and upload the above code to Arduino
  • Type "Arduino" on Serial Monitor and click Send button:

  • The result on Serial Monitor:
  • COM6
    Send
    I received: A I received: r I received: d I received: u I received: i I received: n I received: o I received:

※ Nota:

  • En la actualidad, serialEvent() no es compatible con el Esplora, Leonardo, o Micro
  • Serial functions are not only used for the communication between an Arduino board and Serial Monitor of Arduino IDE but also used for the communication between:
    • An Arduino board and other Arduino board
    • An Arduino board and other sensors/devices
    • An Arduino board and computer (any Serial software on computer)
