How to simultaneously read and transfer all joystick values to a usb port

[Arpitgarg]

Hi, i am emulating joystick, so far i am able to read joystick values and display them on screen, but i want to send them to another computer using tcp socket. I am able to create a socket but can any one tell me how can i gather all the values and send them to tcp socket

Hi everybody
i am new to Qt.I am trying to emulate joystick so far i am able to read joystik value and display it.i want to simulataneous gather all(4) the values and send ot to a port.

I am reading joystick values using getAxis().
I will appreciate any help from ur side.

There is similar thread already : link. Aren't you the same person ?
If not, then well, Qt does not offer any usb-port access methods, you'll need to implement it on your own. On windows, maybe you could use libusb ?

[wysota]

If you are able to read all the values then what's exactly the problem?

[ChrisW67]

Aren't you the same person ?

Or perhaps two people in the same class at school with the same homework assignment.

[Arpitgarg]

Well I want to send all the values simultaneously to tcp socket, and I am not able to figure out how??.

[SixDegrees]

You call socket.write(). See the documentation.

[wysota]

And the same IP? Doubtful. Users merged, merging threads.

[Arpitgarg]

Well, may be I wasn't clear last time, the problem is how to gather all the values together .

[wysota]

What do you mean "together"?

[ChrisW67]

Well, may be I wasn't clear last time, the problem is how to gather all the values together .

The clarity hasn't changed much.

You can store joystick values in a QVector, QList, some user-defined structure with appropriate streaming operators if needed, or just send them one at a time. There is no QBundleOfJoystickValues class to rely on, and there is no universal right way to bundle data. If the receiver imposes a certain format then you should send your data in that format.
