Some of you may have seen the program named "screen receiver" which is part of their "fx-9860G Manager" software package. It lets you show a USB connected calculators screen on your PC, which is neat for some reasons;
- because it makes demonstrations easy, in for example a teaching environment with a PC+projector.
- because it can be used to make "screenshots", of for instance an Add-in you are making. Much easier than using CAPT and then transferring/converting files afterwards.
- because you can.

I made "screenstreamer" which does this as well, but is available for OSs where libusb 1.0 works. This means Linux and Mac OS X, as of july 2009. screenstreamer is open source software.

To get the source code, you need subversion ('svn').To compile and link the sources you will need GCC, make, Qt (for development) and libusb 1.0. They should be easy to get on most Linux distributions.
Once you have that you can follow this video guide for Linux. (I don't use Mac OS X, but if you do and are able to get the program working, I'd love to hear about it.)


or follow written instructions at http://fxsdk.sourcef...=screenstreamer if you don't have flash.

I hope this can be useful, and know there is at least one linux user here

Yeah, It's great. I'll build it.

I think it would be cool to add a Qt GUI in xfer9860 too.

PS: I love the music, what's its name?

I try screenstreamer, it work perfectly!! Excellent job.

EDIT:
After a while, I have an error : libusb:error [handle_bulk_completion] CANCEL: completed URB not awaiting reap?
Why?

Hello,
I tried the screenstreamer, too, but I don't have Linux, so I installed VirtualBox on Windows.
When I connect my fx9860 G2-2 with the virtual Ubuntu, screenstreamer says "Connected!" but no Window appears, like the Video shows.
xfer9860 doesn't work, too.
What may be wrong?

Yeah, I get the same problems.

I think the issue is that they were made for the fx9860G, and we have fx9860GII's, so the code probably needs to be modified.

Unfortunately, I don't have the programming skill to do it at this point.

[Casimo]

Is there any other way to have a screenstreamer?

[flyingfisch]

If you have window$ just use the default casio screen receiver.

[Casimo]

Free?
Link?
Must have...

[flyingfisch]

Just install the trial version of fx-manager. fx-manager will put a shortcut to screen receiver on your desktop. Don't worry, even after the trial period expires, screen receiver will still work.

[Casimo]

Just tested: Screenstreamer only works if GetKey is called, so I can't record my addins .

Screenstreamer does this or casios screen receive function does? They are two different things

[Casimo]

I don't know exactly but I think there's no data sent.

[flyingfisch]

So are you using casio's program or the one in this thread?

[Casimo]

Casio's, because the other one doesn't work, you remember?

[flyingfisch]

OK, you called it screenstreamer, thats why I asked

[Casimo]

I found a solution: SimonLothar showed me syscall 02A0 . Use: void USB_CaptureDisplay( void );.
It is a bit slow, so you should not use it every screen refresh.
