Declarar puertos Serial para Arduino con nombres personalizados

21 Jun 201529 junio 2015 giltesa 2 comentarios

Si estamos cansados de usar el nombre Serial, o tenemos varios puertos como en el Arduino Mega/Leonardo: Serial, Serial1, Serial2, Serial3, etc. y queremos usar unos nombres más descriptivos, puede hacerse de la siguiente forma:

HardwareSerial &pc        = Serial;
HardwareSerial &bluetooth = Serial1;
HardwareSerial &wifi      = Serial2;

void setup()
{
    pc.begin(9600);
}

void loop()
{
    pc.println(millis()/1000);
    delay(1000);  
}

HardwareSerial &pc = Serial;

HardwareSerial &bluetooth = Serial1;

HardwareSerial &wifi = Serial2;

void setup()

{

pc.begin(9600);

}

void loop()

{

pc.println(millis()/1000);

delay(1000);

}
