I am new to working with the serial port library and serial ports in general so please excuse me if this is a simple question.

I am simply trying to write out a 64 to the serial port multiple times in a loop.

The problem is that after the first iteration the serial port never becomes available again.

can someone please explain to me what exactly is going on. Should I be doing something to reset the port on each iteration? Thank you for your help.


This is what my code looks like.



import processing.serial.*;

// The serial port:
Serial myPort;
void setup(){
// List all the available serial ports:
println(Serial.list());

myPort = new Serial(this, Serial.list()[1], 2400);
}
void draw(){
println(myPort.available());


if (myPort.available() == 0) {
delay(600);
myPort.write(65);

}
}

Thank you that is a big help.
