Serial port communication in Java - FTDI D2XX, HID API, X/Y modem

SerialPundit : Serial port communication and much more...

SerialPundit is a Software Developer Kit (SDK) for serial port and HID communication. It has been ported to Linux, MAC, Windows and embedded SE Linux platforms for both 64/32 bit architectures.

It is powerfully configurable for both poll and event driven application designs be it low volume low frequency data or high volume high frequency data.

It eliminates the complexities of serial port programming for different operating systems, allowing engineers to concentrate on their application logic, facilitating faster engineering and development, reducing development cost and time to market.

It is consistent, portable, efficient, testable, reliable, extensible and modifiable.

serialpundit's Issues

SerialComManager.setRTS() causes exception

Hi Rishi,

I'm running Test23 under Win7 64bit and it causes an exception when setRTS() is called (scm.setRTS(DTE, true); )

com.serialpundit.core.SerialComException: The data area passed to a system call is too small.

scm.configureComPortData error

I am getting an error when using the library on a Raspberry3, connecting to a serial port (/dev/ttyACM0).
The error is : Inappropriate ioctl for device when scm.configureComPortControl is called as below.
I tested the port with other libraries and it works so I am sure the serial port is set up correctly.

` private void setSerialComms(String portName, BAUDRATE baudRate, DATABITS dataBits, STOPBITS stopBits, PARITY parity,
FLOWCONTROL flowControl) {

	System.out.println("Creating serial port : " + portName);

	try {
		scm = new SerialComManager();
		serialPort = scm.openComPort(portName, true, true, false);
		scm.configureComPortData(serialPort, dataBits, stopBits, parity, baudRate, 0);
		scm.configureComPortControl(serialPort, flowControl, 'x', 'x', false, false);
		serialBuffer.clear();
	} catch (IOException e) {
		throw new RuntimeException("Could not open serial port: " + e.toString());
	}

}`

Latency timer

I am unable to use the getLatencyTimer and setLatencyTimer methods.
When I use getLatencyTimer I get:
com.serialpundit.core.SerialComException: CM_Get_DevNode_Registry_Property CR_xxxx error code : 0x25

When I use setLatencyTimer I get:
com.serialpundit.core.SerialComException: Given COM port does not exist or may not be a FTDI com port !

But if I use find method findComPortFromUSBAttributes I get the COM port name correctly "COM3".

Why am I unable to use these latency timer methods?

Google Group - Issues and support - Do not use github

Please use google group only to raise issues and support etc. https://groups.google.com/d/forum/serialpundit

Sometimes I can not access github. If your country does not allow accessing google facilities than only raise issues in github.

setBreak/clearBreak for manual break control

Could you please update dynamic libraries so that it is possible to use this library for DMX? It requires microsecond precision.
Even 1/10th of a millisecond (1e-4 s) would be OK.

sp-usb.jar contains wrong win32 DLL

The sp-usb.jar contains a wrong win32 DLL that is not picked up. The name is spusbwinx32.dll instead of spusbwinx86.dll.
Renaming this file solves the problem.

OS X 10.9.5 PortListener and DataListener

Hi,

I am on mac OS X 10.9.5 and running into issues with listeners when the USB port is disconnected.
I create and register the required listeners via, where app implements the ISerialComPortMonitor as following:

    scm = new SerialComManager();
    System.out.println(scm.getOSType());
    System.out.println(scm.getLibraryVersions());
    dataListener = new DataListener();
    eventListener = new EventListener();
    comPortHandle = scm.openComPort("/dev/cu.usbmodem1421", true, true, true);
    scm.configureComPortData(comPortHandle, DATABITS.DB_8, STOPBITS.SB_1, PARITY.P_NONE, BAUDRATE.B57600, 0);
    scm.configureComPortControl(comPortHandle, FLOWCONTROL.NONE, '$', '$', false, false);
    scm.registerPortMonitorListener(comPortHandle, app);    
    scm.registerDataListener(comPortHandle, dataListener);
    scm.registerLineEventListener(comPortHandle, eventListener);

I receive the disconnect/connects events properly, but right after the disconnect ISerialComDataListener starts to flood with errors at:
@OverRide
public void onDataListenerError(int arg0) {
System.out.println("onDataListenerError called");
}

I tried couple of things to unregister and reregister the listeners (event,data) which just guides to detachment of listeners and registration exceptions. Reconnection to the port fails, since the port is still open. Rerun and create new scm instance helps, but detaches the listeners on and I get "Listener not registered" errors on next USB detachment.

How can I avoid the onDataListenerError calls or am I missing something?

Expected behavior.

1. USB connected
2. Create SCM instance and register all listeners Port,Serial,Data
3. Unplug USB -> Port event == 2 should result in stopping serial and data Listeners from interfering with a dead scm connection
   4.Reconnect USB -> Port event == 1 properly should reuse register serial and data listeners without errors.

Another remark: I can kill the JVM by simply trying to unregister the portListeners when onPortMonitorEvent == 2 is called. Which is a stupid circular parent destroy access I know, but it should be handled properly without killing the VM. Again all OSX.

Thanks,
Rtg

If i use scm.writeBytes other threads always freeze

If i use scm.writeBytes other threads always freeze

Example:

runProgressBar();
// WriteToPort
            Object[] openPort = openComPort(selectedComPort.getSelectedItem().toString());
            scm = (SerialComManager) openPort[0];
            handle = (long) openPort[1];
            try {
                // Write delayInbytes
                scm.writeBytes(handle, messagesData.getBytes(), speedSlider.getValue());
                //System.out.println("WRITE COMPLATE : ");
                //System.out.println("write : " + scm.writeString(handle, textSpeedSliderStringValue, 0));
                portRepeatingRead();
            } catch (Exception e) {
                e.printStackTrace();
            }

public void runProgressBar() {
    loadingBar.setVisible(true);
    loadingBar.setStringPainted(true);
    threadProgressBar = new Thread(new Runnable() {
        @Override
        public void run() {
            int i = 0; 
            try { 
            while (i <= 100) { 
                // fill the menu bar 
                loadingBar.setValue(i + 10); 
  
                // delay the thread 
                Thread.sleep(messagePercent1); 
                i += 1; 
            } 
        } 
        catch (Exception e) { 
        } 
        }
    });
    threadProgressBar.start();
}

//-------------------------------------------------------//
runProgressBar(); function start before scm. But always freeze. after finished write port loadingBar.setVisible(true); work. why?

Maven repository is not updated

Hi,

i have seen in the documentation that maven link is:

<dependency>
            <groupId>com.embeddedunveiled</groupId>
            <artifactId>scm</artifactId>
            <version>1.0.4</version>
        </dependency>

but this is not correct, the last version is 1.0.3

the other link with 1.0.4 is
org.bidib.com.embeddedunveiled

also the latest build in the prebuild folder is very new and v1.0.4 is back to Nov 2016

I hope Maven repo is updated with the latest always

Timeout for RX and TX on ISerialIOStream

Hello,
I settled your lib which seem to works (I can transmit and receive in BLOCKING mode) I'm currently on Windows but project will need to work on Linux Desktop and Windows.

I wanted to add timeout for the receive parts, so it seem I need to use NONBLOCKING mode:

_outputStream = (SerialComOutByteStream) _serial.getIOStreamInstance(SerialComManager.OutputStream, _handle, SMODE.NONBLOCKING);
_inputStream = (SerialComInByteStream) _serial.getIOStreamInstance(SerialComManager.InputStream, _handle, SMODE.NONBLOCKING);

Now I'm stuck because I cannot find a place where I can set the Timeout for RX parts.
I saw the following function:

fineTuneReadBehaviour(long handle, int vmin, int vtime, int rit, int rttm, int rttc)

But I don't know how to use it. What are the parameters values. I need for example 3000ms of read timeout.
Also I need to differenciate a timeout exception from an error on the stream (ie: if read function on byteStream return -1 for error on stream, what is returned when it timeout? An exception?).

Any help or answer will be appreciated :-)

Regards.

Where is the native c code?

Cannot make it work on Windows 10 x64

Hi
The library works without a hitch on Linux but I cannot make it work on Windows 10 AMD x64. Every time I try ranning it, the JVM crashes with EXCEPTION_ACCESS_VIOLATION (0xc0000005). I tried on 3 different machines with the same crash. I checked all the libraries (msvcr120.dll, setupapi.dll, advapi32.dll, kernel32.dll) and there they are. There is no consistency in crash log files (hs_err_pid...log). I attach some of these files. It seems like Windows 10 (x64) is not supported but how can I be sure.

Drop "SerialComManager.BAUDRATE baudRate" parameter of SerialComManager.configureComPortData() function

The "SerialComManager.BAUDRATE baudRate" parameter duplicates the "int custBaud" parameter. Nothing prevents from invoking
SerialComManager.configureComPortData() with e.g. BAUDRATE.B115200.getValue() as "custBaud" value.

The first scenario of using configureComPortData() which comes into mind is:

DATABITS db = DATABITS.DB_8;
STOPBITS sb = STOPBITS.SB_1;
PARITY p = PARITY.P_NONE;
int userTypedBaudRate;

// Some code affecting db, sb, p and userTypedBaudRate here

...configureComPortData(handle, db, sb, p, BAUDRATE.BCUSTOM, userTypedBaudRate);

javax.comm Implementation

Hi, I'm trying to wrap SerialPundit into Javax.comm API, cause javax.comm works only on linx86 or solaris

I need it to be able to connect to serial devices running on any OS and x86 or x64 Java, because a lot of legacy code used javax.comm API.

Currently i cannot test it, but i have a question, in legacy code i have something like:

serialPort.addEventListener(myListener);
serialPort.notifyOnDataAvailable(true);

and in MyListener ->

public void serialEvent(SerialPortEvent arg0) {
	if(arg0.getEventType() == SerialPortEvent.DATA_AVAILABLE) {
		while(serialPort.getInputStream().available() > 0 ) {
		    byte b = (byte)serialPort.getInputStream().read();
                //SomeCode
                }
               //SomeCode
       }
}

In my implementation of javax.comm.SerialPort i have:

public void addEventListener(SerialPortEventListener spel)  {
		
		//TODO Handle EVENTS SerialPortEventListener wrap to ISerialComDataListener or ISerialComEventListener
			scm.registerDataListener(handle, new ISerialComDataListener() {
				@Override
				public void onNewSerialDataAvailable(byte[] data) {
					// TODO Auto-generated method stub
				}
				
				@Override
				public void onDataListenerError(int errorNum) {
					// TODO Auto-generated method stub
				}
			});
	} 

And now i see some problem. Cause in javax.comm API code i'm recieving event that data is available and then reading bytes from input stream.

But in your code i see onNewSerialDataAvailable(byte[] data), so that means that data is already readed, it's in data variable, so serialPort.getInputStream().read() will not work? Or Im wrong?

ISerialComEventListener and CTS change

Hello Rishi,

The ISerialComEventListener is only called once if linestatus CTS changes from 1 to 0 but not if line status changes from 0 to 1.
I'm testing on Windows 10 64-bit and I use FLOWCONTROL.RTS_CTS.

Get InputStream from SerialComManager

I'm about to make use of marine api.

To start off, an InputStream is needed, but I don't know whether the first line is correct or not:

InputStream is = (InputStream) scm.getIOStreamInstance(SerialComManager.InputStream, handleGps, SMODE.NONBLOCKING);
SentenceReader sr = new SentenceReader(is);
sr.addSentenceListener(this);
sr.start();

If not, is there any other way?

Thanks!

Add support for armv7 to sp-usb.jar

Hi Rishi,

Could you add support for ARMv7 to sp-usb.jar? Running on a Bananapi it complains about missing spusblnxarmv7hf.so .

Regards,
Andreas

A better readme.md?

Nice work! perhaps a few trivial fixes for people to better understand what your library can do?

• Github parses README.md as markdown so take advantage of it.
• Include example usage (its now in PDF which github can't show) in the README.md or INSTALL.md?

2018-03-25 20:40:59 JNI call ThrowNew failed to throw exception !, FormatMessageA(), error code : 15100

Hi;

I'm try only this:
`class HotPlugEventWatcher implements ISerialComUSBHotPlugListener {

@Override
public void onUSBHotPlugEvent(int event, int usbvid, int usbpid, String serialNumber) {

    if(event == SerialComUSB.DEV_ADDED) {
        System.out.println("DUT added, running automated tests for this device !");

    }else if(event == SerialComUSB.DEV_REMOVED) {
        System.out.println("DUT removed, running tests, if any, to be run after device removal !");
        System.out.println("usbvid : " + usbvid);
    }else {
    }
    
}

}`

If I'm unplug my usb Device from USB port netbeans show this message:

serial library seems to be missing from maven

Hi, I tried to import core and serial using gradle from the Maven repository.
I could only find the core module, not serial, in the repo.
Is this by design? Or can you add it?
Thank you for your interest.

Windows DLL depends upon debug DLL

Based upon this discussion: https://groups.google.com/forum/#!topic/serial-communication-manager/pZIrrdn43nY it appears that the windows DLL depends upon MSVCR120D.DLL (as well as IESHIMS.DLL).

I'm not a Windows C++ developer, but from what I've read it appears that the *D.DLL files are debug only and not redistributable, and I've been unable to figure out how to get a copy of MSVCR120D.DLL (I installed VS 2013 Community edition, but still can't find the DLL anywhere - not sure if I need to build something that uses it?).

Ideally the binaries included with the Java library should not require additional DLLs to be installed - but if this is not possible it would be preferable if the libraries were available from the Microsoft Visual C++ redistributable download.

occasionally corrupted data when sending on macOS + CP2102

I observed occasionally corrupted data (about every 20 times) when sending a simple String (about 10 chars) as byte array via writeBytes(serialHandle,data) on macOS 10.12.3 using CP2102 USB-Serial converter.

The same code using Bluetooth serial connection works (to HC-05 BT-UART-Dongle).
The same code on Win10 works with both, CP2102 and Bluetooth.

When using jssc, there are no issues with the combination macOS + CP2102

I assume some issue with the driver communication.

SerialComUSB: Raspi 4 is not supported

Hello Rishi,

On a Raspi 4 the SerialComUSB shows the following exception:

tty2com -- cannot read meta info

Hi,

i just compiled and installed tty2com driver. All seems OK, I am able to communicate with picocom and by python serial library and no errors in log. But i am not able to read meta info, as described in README:

head: error reading '/proc/sp_vmpscrdk': Invalid argument

The cat provides the same error message. The sp_vmpscrdk permissions:

Shared library not in sp-tty.jar

Hi!

I want to test my USB-Relay/CP2104 with your test77 example. Unfortunately the lib cannot load the shared lib:

"Can not get shared library spcp210xrwinx64.dll resource as stream from sp-tty.jar file !"

Indeed, in the sp-tty.jar there is no such file. Currently not implemented?

Native libraries

Is the source code for the native libraries available ?

I created an web apps with spring boot. When application start, I start to do a blocking read on the serial port. I use serialPundit library.

If a member don't have a card assigned, I don't want to suspend the thread, do another process on the serial port and resume the thread.

When a user don't have a card assigned, I have this code who need to be called.

            }
            return new ResponseEntity<>(HttpStatus.NO_CONTENT);
        }

It's seem to have an issue about the thread.

When I start the application,

run is displayed.

I do a call to this URL: http://localhost:8080/members/1/card No card assigned.

theses string are displayed

updatedCardId
suspend

run 2: I/O operation unblocked !

I pass a card over the scanner

theses string are displayed
id
resume

Thread don't seem to run anymore because if I try to scan the card again, nothing happen. Nothing is displayed. Just don't understand because there is only one who have access to serial port.

Sometime get another result

run
run before read
updateCardId
suspend
updateCardId: before read

scan the card, but nothing happen,
scan the card again and get

updateCardId: after read
updateCardId: E00124ABF84CE001
resume

Card id should be E004010024ABF84C, seem like some issue can happen with the read

OS X 10.9.5 Library Versions

Hi,

I am on mac OS X 10.9.5 and use System.out.println(scm.getLibraryVersions()) to get the versions of the libs. However it looks like there is a mismatch between the Java and native lib.

Java lib version: 1.0.3
Native lib version: 1.0.2

Are the Versions compatible?

Thanx,
Rtg

JNI call ThrowNew failed to throw exception

Hello Rishi,
I tried to run the example but I got this error in the Eclipse console, what does it mean or why it happens?

JNI call ThrowNew failed to throw exception !, FormatMessageA(), error code : 15100
com.serialpundit.core.SerialComException:

	at paquetePruebaSerial.Example.main(Example.java:14)

The line 14:

            long handle = scm.openComPort("COM5", true, true, true);

I was working on a machine with Win8.1 (AMD64)

XP Compatibility

Is SCM compatible to Windows XP ?
I tried to run the prebuilt-release scm-1.0.4.jar on Windows XP SP3 but I can't get it work.

Exception in thread "main" java.lang.UnsatisfiedLinkError:

I added the missing MSVCR120.DLL to system32 directory but
still Dependency walker shows a problem with the following 2 DLLs.

ADVAPI32.DLL  (RegGetValueW  *function is marked red)

How to detect Parity errors?

The library won't enable parity check on Windows 10 x64.

I've tried this example that you provided https://github.com/RishiGupta12/SerialPundit/tree/master/applications/d1-blocking-read-com

with enabling ParFraError like this:

scm.configureComPortControl(handle, FLOWCONTROL.NONE, 'x', 'x', true, false);

after this i printed:

System.out.println(Arrays.toString(scm.getCurrentConfiguration(handle)));

and i got this:

[DCBlength : 28, BaudRate : 19200, fBinary : TRUE, fParity : FALSE, fOutxCtsFlow : FALSE, fOutxDsrFlow : FALSE, fDtrControl : DTR_CONTROL_ENABLE, fDsrSensitivity : FALSE, fTXContinueOnXoff : TRUE, fOutX : FALSE, fInX : FALSE, fErrorChar : FALSE, fNull : FALSE, fRtsControl : RTS_CONTROL_ENABLE, fAbortOnError : FALSE, fDummy2 : NA, wReserved : NA, XonLim : 2048, XoffLim : 2048, ByteSize : 5, Parity : 1, StopBits : 0, XonChar : �, XoffChar : �, ErrorChar : , EofChar : , EvtChar : , wReserved1 : NA]

fParity is false, but it should be true

can you provide com.embeddedunveiled.native, thanks

This project is very excellent, com.embeddedunveiled.native folder is invisible, can you provide it.

Application Crash when starting multiple instance even using new prebuilt releases

Hi
Thanks for maintaining this great library.
I Imported the serilapundit application "serial terminal emulator" in my eclipse workspace,
and opened two instance. As soon as I clicked open button selecting one of the port the other instance terminated, throwing a fatal error and producing an error file. I tried it on Windows as well as on Linux both 32bit and 64bit platform and the problem is same. I am attaching the eclipse console output and the generated error file. Kindly look into the matter.
