Java Rxtx Usb Serial Ch340 Software Serial Communication Port

You find here all steps needed to setup environment in Eclipse for development and testing using serial communication port.

Java Rxtx Usb Serial Ch340 Software Software Without Physical

Moreover described technics allow you to develop software without physical equipment and test it as well.

Implementations of the API are currently available only for Solaris SPARC, Solaris x86, and Linux x86.

Library provides the same API as Suns Java Communication API so migration to RXTX library is very simple - you have only to change imports declarations.

Java Rxtx Usb Serial Ch340 Software Zip Downlowded RXTX

Unzip downlowded RXTX package into temporary directory and copy RXTXcomm.jar, rxtxSerial.dll and rxtxParallel.dll files into lib directory.

Dll files are located in Windowsi368-mingw32 directory of RXTX library.

Next click the right mouse button on the JavaSerial project and go to the PropertiesJava Build Path.

To do this click the right mouse button on JavaSerial project and go to the PropertiesJava Build Path.

Click on Native library location: (None) and click Edit button.

After the Native Library Folder Configuration dialog window appears click on Workspace button and select JavaSeriallib folder.

After all start clicking OK buttons until you back to the begining.

If you do not see presented output please repeat configuration process again.

You will be able to connect end-point device software emulator to the one of serial ports available in the operating system and the application to the second of available serial ports.

Serial ports within each pair could be connected together through the virutal RS232 wire.

Then you can connect to the first emulated serial port an end-point device emulator and to the second serial port the application making a communication between these parts.

It is great solution if you dont have access to the device to which you develop RS232 communication software and if you dont have any serial port on your laptop or PC - the only thing you should have is a specification of RS232 communication between device and application.

Presented example will be very simple to show important communication issues and best practices.

You can extend this sample to create more sophisticated applications.

Each byte is passed to the protocol manager which handles all protocol issues (for example recognizes messages from raw bytes).

When end-point device breaks the opened InputStream then in.read() method starts to return -1 value without blocking.

Because waiting for external device in infinite loop without in.read() blocking method could be destructive for performence of operating system sleep method is introduced to decrease number of in.read() executions.

The interface of Protocol implementation allows to inform protocol manager about each incoming byte and about broken stream situation.

If you develop more complicated example (and I am sure you will do) logic of triggered actions depending on recognized message should be placed in external class (some kind of interpreter).
