Java Connect To Serial Port
Possible Duplicate: Java Serial Communication on Windows Friends, I want to connect and transfer data to COM PORT (either virtual or original) in JAVA? Using Java for Serial Communication Introduction. Because of Java's platform-independence, serial interfacing is difficult. Serial interfacing requires a standardized API with platform-specific implementations, which is difficult for Java. Unfortunately, Sun didn't pay much attention to serial communication in Java.
The Arduino Reference text is licensed under a Creative Commons Attribution-Share Alike 3.0 License. Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Arduino serial include. Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/.
Java Connect To Serial Port In Linux
Jan 22, 2014 An Asynchronous port on the computer used to connect a serial device to the computer and capable of transmitting one bit at a time. Serial ports are typically identified on IBM compatible. How to connect to serial port using java Sat Jun 30, 2007 4:27 pm This is the code of connecting to serial port and writing streams and reading from it.This project was already exists on some page. Class SerialPort java.lang.Object javax.comm.CommPort javax.comm.SerialPort. Public abstract class SerialPort extends CommPort. An RS-232 serial communications port. SerialPort describes the low-level interface to a serial communications port made available by the underlying system. In the first episode of the Ultimate Arduino Tutorial Series Edition 'Advanced Programming', I demonstrate how to establish a serial connection from a Java application to the Arduino Uno, and then. Connect directly to a port. Use a network client to connect to the service network Base Port + serial port number e.g. The SSH base port is TCP port 3000, so SSHing to TCP port 3001 directly connects you to serial port 1 SSH to the Opengear device, login adding:portXX to your username.
First of all, I know this question has been asked a lot but I can't find any answer that solves my problem. So when I try to use processing to write stuff to the serial monitor of the Arduino it says that the port (in my case 'com3') is busy. I have no idea with what it could be busy because I already set a delay on the reading of the serial-monitor.
Arduino code:
Processing code:
I know it is really basic but I made the code as small as possible while still showing the problem
For example, if the function of TIME$ and DATE$ are entered then the output is time and date that is known by the system. Numeric Functions are mathematical calculations. While String Functions are strings based. Free download gw basic software. Another part of GW-BASIC is Functions i-e numeric functions or string functions.
Thanks in advance

It seems, that you try to access the Serial port from your running Processing sketch at the same time as from the Arduino Serial Monitor.
It is important to note, that the Arduino IDE Serial Monitor is itself a process, that communicates with your Arduino. The Arduino can not, at the same time, talk to the Serial Monitor and another Program.
But you are halfway to monitor what your Arduino has to say. Use Processing instead.You are already sending the message back. All you have to do is to log incoming Serial messages in your Processing app.

Just add this to your Processing draw loop:
Close the Arduino Serial Monitor, run the Processing Sketch and you should see whatever you sent (using Serial.print in Arduino) in the Processing Console.
Serial.print, just like Serial.read are functions to communicate with any program on the computer once you plugged the USB cable. Serial Monitor is one of them, but there are many others and among them is Processing.
