Serial Library: Connect and disconnect

in Core Library Questions • 2 months ago

I need to connect and disconnect the serial port while my draw() loop is running.

I can connect once (in setup()) using:

myPort =

new Serial ( this , Serial.list()[0], 9600);
And I can disconnect (in draw()) using:

Serial(close);

How can I re-connect again in draw()?

Just a guess as I don't have such devices. Create 2 methods:

createConnection() .
closeConnection() .

Within closeConnection() , make myPort = null; as also a flag to indicate it's not active anymore:

import processing.serial.*;
Serial myPort;

void draw() {
  if (myPort == null)  createConnection();
}

void createConnection() {
  myPort = new Serial(this, Serial.list()[0], 9600);
}

void closeConnection() {
  myPort.stop();
  myPort = null;
}
