After seeing Simplecam was released for OS3.x today I thought about it
would be nice to use it. But these tools from MorphOs use poseidon.library,
so we need some sort of library wrapper between poseidon.library and the
OS4 USB libraries. Maybe - is there anybody outthere already working on this ?

@Beeblebrox

afaik the source code of simplecam is also available for download.
so a straight port to os4 (using the os4 usb stack) should be the easier solution.

byebye...

Not sure about Poseidon compatibility, but I believe someone is working on an OS4 port of libusb.

simplecam and canontoolbox are tools to acces a canon
digital camera. Have a look on

http://member.ycn.com/~hausrup/

so far just for OS3.x and Mos. I thought a bridge/wrapper between
poseidon and os4 USB would let us use USB drivers written for
poseidon (OS3.x/Mos)

@gnarly

Yes, there is work being done on libusb by the OOo team

@Beeblebrox and the rest

I read up on SimpleCam, then went and read up on libptp2 to see what cameras it supports. It's more than just Canon, cause my Kodak CX4200 is one of the supported ones!

There are quite a few brands that this covers, so it would be a welcome addition for my A1.

The other program is the one that is Canon only, I believe.

This would be a good short term solution, as it would bring a lot of 68K software supporting usb (Turboprint, VHI Studio, etc) to OS4. That would be a nice bridge while waiting for native software packages. Anyone familiar with the poseiden api???

Before anyone else comments, it does depend on the functionality of the AOS4 usb stack, which may not do everything poseiden currently supports (waiting for update #3..).

Though I would appreciate somebody writing a hardware driver for PCI cards in OS4 to run Poseidon on it (the 68K version, as far as concerned there won't be OS4 PPC native binaries in the (near) future), trying to write a wrapper to use the Poseidon classes with the OS4 stack is a breach of licence terms and I would be forced to take measurements to inhibit this. It would be sad, if I had to add code to protect my work from being used illegally in other projects or OS4 in general.

Please, don't be offended for this statement. Anyway, writing a "wrapper" would probably be a waste of time, as Sirion and Poseidon handle things quite differently IMO.

hm, dont think this is clear for now.. What I mean is something like a library emulation.
Somethink like the powerup emulation library for warpos. Using the same interface
from your library for making it compatible. This is also beeing done by various icq
clients that dont rely on mirabilis code. So none of your code is beeing used. If
you dont have a patent on your poseidon driverinterface it would not be illegal.
Furthermore you wouldnt get any damage on poseidon sales, because poseidon is not
and I think will not become part of OS4. At least you could even write a library emulation
yourself and get a shareware amount on distributing it..

aargh.. (edit)

me again. I thought the driver is f.e. simplecam. Did not understood these classes
in poseidon are drivers.. So please explain me what simplecam does - is there any code
supporting canon cameras or is it just a gui and the drivers are all in poseidon ?

So are you are saying is that it is illegal to take Poseidon files that I obtained from a legal purchase of MorphOS and copy them over to my OS4 box which I obtained legally and run them via some form of an emulator? In fact, you would put in code to prevent this from working if you had to?

Am I interpreting this correctly?

That depends. Does the Poseidon license say that those files can only be used with the copy of MorphOS with which they were supplied (or something along those lines)?

Reading yet another license isn't what I'm after. What I'd like to know if I am interpreting the intent of the license correctly. Usually these licenses forbid you from running on more than one computer at a time--standard stuff and very understandable. This license seems to go a step further and limit what kind of computer you can run the software on. I'd like Chris to clarify this himself so there is no question as to the intent.

That is what I was suggesting as well, a "fake" poseidon library that presents that api to applications, but implements the functionality with calls to the OS4 usb stack. No actual poseiden executable would be used at all. That should be possible even if the internal operation of the two is implemented differently, though I'll admit I haven't looked at either one closely to see if there are any issues.

@Beeblebrox

Any parts of Poseidon (executables, documentation, includes, SDK, etc.) may not be used outside the scope of the package. Hence, if somebody would write a wrapper library, that would allow the original Poseidon classes to run, I would consider this illegal. Writing a wrapper that allows third party programs (e.g. SimpleCAM) to work under the OS4 stack would be okay, I suppose. But then again, I doubt somebody will write such a wrapper, because it is a lot of work. It would be easier to rewrite the usb parts of the applications to the OS4 stack than going for a wrapper library.

Yes, if you only use parts of the package, but not the whole package (especially a faked poseidon.library). Poseidon V2.2 is licenced to MorphOS, as to some OEMs on AmigaOS3.x. It is not licenced yet to OS4. It is a similar case like saying Roadshow from OS4 cannot be used on MorphOS, because of the licence involved.

If somebody tries to do something with Poseidon that it was not intended to be used for, e.g. to get around the licencing fee/keyfile, and therefore do damage to me (morally or monetary), I would quickly take countermeasures. Or as well, take my hat and go.

@Beeblebrox

On the site there is actually also the source-code of SimpleCam. Maybe someone with
clue about USB can just port those tools to the OS 4 USB-Stack ? I think it would be very
useful to have (myselves I got a Camera supported by SimpleCam...).

Thanks for the explanation Chris.

Do you have any interest in making a wrapper library for the OS4 usb stack yourself (I'm assuming that the real Poseiden couldn't run at the same time as the OS4 stack)? I would be willing to pay for something like this, and you certianly know the Poseiden API. While I agree that apps can be ported directly to OS4, there are existing 68k comercial apps that may never get updated that I could use now, like VHI Studio.

@d_w_cook

I neither have time, nor the interest, nor the hardware, nor the documentation to develop a wrapper library for the OS4 stack.

Talking about IOSpirit applications, at least FxScan is supposed to go through a library supporting both the Poseidon API and the Sirion stack (which later became the OS4 stack). Regarding VHI Studio: The PenCamTool and pencam.vhi driver sources are included in the Poseidon SDK.
