QSerialDevice v 0.2.0 released

[kuzulis]

Hi

So, announces release: QSerialDevice v 0.2.0

Many amendments, write makes no sense, therefore, give a brief clipping annotations:

QSerialDevice - a cross-platform library for serial devices, which uses framework Qt4 (see http://qt.nokia.com/).

Requirements:

OC: Win2K/WinXP/WinVista/Win7 or any GNU / Linux distribution
Qt4:>=4.5.0
Processor: any (which is supported by Qt4)
Compiler: any (which is supported by Qt4)

Notes:

Due to the fact that I (the author) do not have the opportunity to test the library at all possible operating systems, all compilers, processors, etc. - It is possible that the library in some cases will not work: (.
Library tested only on:
OC: Windows XP Pro Sp3 (win32) and GNU ArchLinux x86_64
Qt4: from 4.5.3 to 4.6.2
Processor: AMD Athlon 4400 + 64x2 Socket AM2
Compiler: gcc, MinGw
Theoretically (with minor fixes source code) can ensure that the library has worked on other platforms.

QSerialDevice Library contains the following classes:

* AbstractSerial
* SerialDeviceWatcher
* SerialDeviceInfo

AbstractSerial

Class AbstractSerial - provides a self-contained set of methods and properties for light and easy to work with serial devices (serial port) of your PC (or other device).

The class supports the following features:
- to set the speed of data exchange
- to set the number of bits of data
- to set the number of stop bit
- set modes parity
- to establish regimes of control flow
- set timeout symbol
- write data to the serial device
- read data from serial device
- manage such lines as a port: DTR, RTS
- reading of such lines as a port: CTS, DSR, DCD, RI, RTS, DTR, ST, SR
- automatically receive notification when:
- receiving at least one byte (character) in the input buffer
- writing the last byte in the output buffer
- change of status of the serial device (for errors, etc.)
- to get the current value of the number of bytes in the receiving buffer
- set timeout joining at least one byte (character) in the input buffer

(see further description AbstractSerial and source code)

SerialDeviceWatcher

Class SerialDeviceWatcher - is a helper class for the monitoring of serial devices.

Class provides the following features:
- to obtain a list of names of all serial devices that are available in the system
- automatically receive notification when adding / removing of any serial device

(see further description SerialDeviceWatcher and source code)

SerialDeviceInfo

Class SerialDeviceInfo - also is a helper class to obtain information about the serial device.

Class provides the following features:
- to get "friendly" name interesuyushego us serial device
- to obtain the "description" interesuyushego us serial device
- to get VID and PID interesuyushego us serial device (experimental)
- we are interested to check the serial device to the existence of
- we are interested to check the serial device on employment (lock)
-, etc.

(see further description SerialDeviceInfo and source code)

Is there something special I need to do to build QSerialDevice on an Ubuntu Linux platform? I have no trouble building and running successfully on windows, but building on Linux I get

/moc_serialdevicewatcher.cpp:12: error: #error "The header file 'serialdevicewatcher.h' doesn't include <QObject>."

If I add "#include <QObject>" to serialdevicewatcher.h I get

/moc_serialdevicewatcher.cpp:78: error: invalid use of incomplete type ‘struct SerialDeviceWatcherPrivate’

and

/../QSerialDevice/serialdevicewatcher.h:33: error: forward declaration of ‘struct SerialDeviceWatcherPrivate’

moc_serialdevicewatcher.cpp:78 is

case 1: d_func()->_q_processAvailableNotifier(); break;

case 1: d_func()->_q_processAvailableNotifier(); break;

As I try to fix these, the errors start to multiply. Any ideas?

[kuzulis]

I just checked the compilation of: svn checkout svn://scm.fireforge.net/svnroot/qserialdevice
and I have all good compile. OS ArchLinux x86_64.

Try has make the so:
- Remove from the project all Makefile, *. moc, *. obj files and then compile. (Or equivalent to do: # make distclean)

[jnadelman]

Thanks. That was helpful. Builds fine now.

[cutie.monkey]

QSerialDevice is very helpful! I'ved been using this in LINUX and WINDOWS. Thanks to the author..

[kuzulis]

NEWS!

QSerialDevice moved to Git: http://gitorious.org/qserialdevice

Now the main line (master) and the development will be on Git!!!

[pherthyl]

Cool. I've been using QextSerialPort, but it isn't without its problems. How is QSerialDevice different/better than QExtSerialPort? Why was it created?

[kuzulis]

Cool. I've been using QextSerialPort, but it isn't without its problems.

What's the problem with QextSerialPort?

How is QSerialDevice different/better than QExtSerialPort?

Difference is enormous. As in the very architecture of the library, and additional opportunities.
There are only a small minus, which lies in the fact that at the moment fully supported by OS Win 2k/XP/Vista/7 + GNU / Linux. Other OS partially supported.
More information you will find viewing the source code and documentation. And compare for yourself.

Why was it created?

Yes just like that! You will not believe it!
I am not happy QextSerialPort. I could add a functional - but this would alter the entire architecture QextSerialPort. But then it was already not QextSerialPort - but something else!
So I decided to create a new library from scratch.

----
Another remark for all:
Need help in implementation of native support for classes SerialDeviceWatcher and SerialDeviceInfo for MacOSX and other operating systems (if possible).
It would be nice for that "steal" code from QextSerialPort - but I do not know MacOSX and I have no time! Still, it's summer - a summer to relax!

[pherthyl]

What's the problem with QextSerialPort?

I never got the enumerator to work properly, and also never got it working by listening for readyRead. It seems to only work using polling.

More information you will find viewing the source code and documentation. And compare for yourself.

Thanks, will do. I guess the other difference is that QextSerialPort is BSD or public domain instead of GPL...

[jnadelman]

I was able to get QSerialDevice working on linux and windows without too much trouble. I was only able to get QextSerialPort working on windows.

Hello all,

I'm trying to compile QSerialDevice v 0.2.0 on windows with VisualStudio 2008.
* I've created a CMakeLists file (attached)
* When I compile the project i have the two (similar) following errors:

- in moc_serialdevicewatcher.cxx, I get a compiler error because I use the undefined type SerialDeviceWatcherPrivate in the function SerialDeviceWatcher::qt_metacall (the d_func() is supposed to return a SerialDeviceWatcherPrivate object)

- in moc_serialdevicenotifier.cxx, I get a compiler error because I use the undefined type SerialNotifierPrivate in the function SerialNotifier::qt_metacall (the d_func() is supposed to return a SerialNotifierPrivate object)

If in moc_serialdevicewatcher.cxx I replace the include file
#include "../../qserialdevice/serialdevicewatcher.h"
by the include file
#include "../../qserialdevice/serialdevicewatcher_p.h" in

And in moc_serialdevicenotifier.cxx I replace the include file
#include "../../qserialdevice/serialnotifier.h" in
by the include file
#include "../../qserialdevice/serialnotifier_p.h"

I can compile everything without problem. However I get linker errors like this :

warning LNK4006: "public: virtual struct QMetaObject const * __thiscall SerialDeviceWatcher::metaObject(void)const " (?metaObject@SerialDeviceWatcher@@UBEPBUQMetaObjec t@@XZ) déjà défini dans moc_serialdevicewatcher.obj

which i think suggest that i have problems with my .moc files

Would anyone have some insight on why I get this compiler error and how I could compile the library correctly with MSVS2008 ?

Thanks a lot,
Best

I have the same problem, but also distcleaning the problem is still present.
I am able to correclty compile the integrated library

here is the project:
http://dl.dropbox.com/u/7966431/testQSer.zip

I run Ubuntu 9.10 64 bit, gcc 4.4.1, qt 4.5.2

thanks

Maybe I am wrong but I can check only tomorrow morning

thanks

Unfortunately I must confirm the problem, even if I delete all generated files:

the errors are:

Try download current Git snapshot and rebuild library.
Classes SerialDeviceWatcher and SerialDeviceInfo more is not supported (deprecated). Try class SerialDeviceEnumerator.

Hello, I´m using QT4.6.3 in conjunction with VS2008.... so i downloaded QSERIALDEVICE 2.0 and tried to compile the QserialDevice.Lib in the way documented in the file readme_en.txt....... so qmake BuildIntegr........... works fine....the when i type the command "make" ther appears the Error Message "makefile:83: *** missing separator. Stop" so the tree under the directory build stays nearly empty..... Do anyone have an Idea? Without the Lib there ist no way to try serial programming Thanks for every help -Ralf-

1. Try download from Git : http://gitorious.org/qserialdevice
2. The current version (Git) is not 0.2.0! (It is closer to 0.3.0).
3. Do not use "readme_en.txt" and etc.
4. To build the library, use only "BuildLibrary.pro":

#qmake BuildLibrary.pro
#make

(Preset project to build DEBUG or RELEASE)

[rmeeh]

Thank´s for your mail.
I don´t have a cvs system in use, so i´m not able to download the sources.
Is there no way to get a ZIP or rar archive with an actual snapshot? Normaly i develop small projects for Amateur Radio (technical things) so i don´t need a cvs. This time i need a serial asyncronus communication to an ATMEGA Microcontroller which controlls an Axis.......and i´ve never used a CVS in my life ;-)
best Regards, -Ralf-

[QUOTE=kuzulis;158746]2 rmeeh,

You're not looking for and inconsiderate!

Thank´s very much, you´re right, how could i belive that you would not be prepeared..
with a little trouble the library compiled using Visual Studio 2008
Now the work will start understanding the classes.
Have a nice weekend
