Serial Message Chopped

davidred15

Hi All,

I am using the default SimpleSerialRead example. I verified the serial is working on Arduino Monitor/ Putty and set the baud rate to 250000. I am only getting 2-digit numbers by println() to console instead 4 digit numbers with other serial monitor. I also tried to slow the baud rate to 115200. Still not working.

Please provide ino and pde code showing your approach.

commented code is the arduino code

    /**

    import processing.serial.*;

    Serial myPort;  // Create object from Serial class
    int val;      // Data received from the serial port

    void setup() 
    {
      size(200, 200);
      // I know that the first port in the serial list on my mac
      // is always my  FTDI adaptor, so I open Serial.list()[0].
      // On Windows machines, this generally opens COM1.
      // Open whatever port is the one you're using.
      String portName = Serial.list()[0];
      myPort = new Serial(this, portName, 250000);
    }

    void draw()
    {
      if ( myPort.available() > 0) {  // If data is available,
        val = myPort.read();         // read it and store it in val
        println(val);
      }

    }



    /*

        val = analogRead(3);    // read the input pin

      Serial.println(val);             // debug value
