Sending data over serial

Blad2021

Hello all,

I'm working on a program that will be sending a text file to a machine over serial communication. So far the program looks great however I have not been able to find how to program the application to start and stop bits, and even or odd encoding. Is this possible to be done using the serial library? Again this is still a work in progress.

Please advise, - M

My code so far:

//import processing.serial.*;
import controlP5.*;
import java.io.*;

//Serial myPort;
ControlP5 cp5;
int waitTime = 500;
boolean connectionStatus = false;
String fileName = "textfile.txt";
char endChar = '\n';
boolean stopTrigger = false;
Textarea consoletext;
//Println console;

void setup()
{
  noStroke();
  size(800, 520);
  cp5 = new ControlP5(this);
  cp5.enableShortcuts();

  cp5.addTextlabel("title")
    .setText("Monarch Interface Application")
    .setPosition(10, 10)
    .setFont(createFont("Arial", 22))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addButton("stopButton")
    .setSize(90, 50)
    .setFont(createFont("arial", 22))
    .setCaptionLabel("STOP")
    .setPosition(20, 70)
    ;
  cp5.addButton("sendButton")
    .setFont(createFont("arial", 22))
    .setSize(90, 50)
    .setCaptionLabel("SEND")
    .setPosition(20, 140)
    ;

  cp5.addTextfield("waitTimeInput")
    .setId(6)
    .setPosition(20, 420)
    .setSize(200, 35)
    .setFont(createFont("arial", 20))
    .setAutoClear(false)
    .setCaptionLabel("Wait per Line")
    .setText(Integer.toString(waitTime))
    ;
  cp5.addTextfield("fileNameInput")
    .setId(6)
    .setPosition(20, 340)
    .setSize(200, 35)
    .setFont(createFont("arial", 20))
    .setAutoClear(false)
    .setCaptionLabel("Filename")
    .setText(fileName)
    ;
  cp5.addTextlabel("statusLabel")
    .setText("Status:")
    .setPosition(20, 220)
    .setFont(createFont("Arial", 20))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addTextlabel("statusLabelb")
    .setText("DISCONNECTED")
    .setPosition(55, 255)
    .setFont(createFont("Arial", 20))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addTextlabel("ctext")
    .setText("Console | Serial Injection")
    .setPosition(365, 3)
    .setColor(color(200, 0, 0, 255))
    .setFont(createFont("Arial", 18))
    ;
  consoletext = cp5.addTextarea("txt")
    .setPosition(370, 30)
    .setSize(420, 480)
    .setFont(createFont("", 12))
    .setLineHeight(14)
    .setColor(color(255, 255, 255, 255))
    .setColorBackground(color(100, 100))
    .setColorForeground(color(255, 100))

    ;

  //console = cp5.addConsole(consoletext);
