Camera Drivers and SDK

roysalisbury

I've begin writing some capture software so I can crate an All-Sky camera with my ASI174MM. I'm trying to make this a simple setup and very low power. With that in mind I have tried a few fanless Micro-PC's that are powered via 12V. I'm doing this under Windows and C# (not a linux guy).

I've finding that they are just not powerful enough to both capture AND encode video and anything over 10 fps. Then the system will also need processing time to do motion detection and other tasks.

I have one of the new Intel Joule 570 dev boards that I want to try. This is an ATOM 1.7GHz quad core and I think it may do the trick. Problem is, I need to Run Windows 10 IoT on it and not the full Windows 10. This is both good and bad. The good part is it will have very little overhead. The bad, I don't know if the Windows drivers for the camera will install. It is a 64bit intel OS (not ARM).

So my question, will the drivers for the camera install and will the .dll's for the SDK work ok?

Thanks

Well, I tried creating the necessary driver package from the existing x86/x64 drivers, but I'm not able too. Looks like they need to be signed by the manufacture.

Could the SDK devs please provide the necessary drivers for Windows 10 IoT devices (x86, x64, arm).

Thanks!

P.S. Here is a possible starting point...

https://developer.microsoft.com/en-us/windows/iot/docs/peripheraldrivers

Well, I went another route. I copied the x64 drivers directory from:

C:\Program Files (x86)\ZWO Design\USB3_Cameras\driver\x64

to a temporary directory on my IoT device (it the Intel Joule 570x)

Then ran the following command on my device

C:\devcon dp_add C:\TEST\x64\ASICAMUSB3.inf

Then rebooted. Not it lists the ASI174MM as a connected device... So now I'll write a simple program to see if the SDK works.

Fingers crossed!

Does not look like the SDK will work. Seems to be two reasons...

1. The 64 bit version of the dll is not the same as the ASICamera2.dll .. Different signatures. I can change the signatures, but not sure what other issues I might come up with (not for this camera?).

2. There may be some dependencies that the .DLL relies on that are not part of Windows 10 IoT (SETUPAPI, KERNEL32, USER32, ADVAPI32).

Will need assistance from the SDK developers...

Found something else... Looks like API's on normal Windows (e.g, ADVAPI32.DLL) have been moved to other modules (e.g., API-MS-WIN-CORE-REGISTRY-L1-1-0.DLL).

So will need a windows universal version of the .DLL for the SDK. Would have been nice if MS released proxy .DLL's for changed locations...

If the source for the SDK was available, I might try updating it myself, but its not...

we will try to build a new version of Iot although we don't have one board for testing

roysalisbury

I'll be happy to test it for you... I can do both 64 bit Intel and ARM.

Any chance you have had time to look at this?

Hi Roy

do you know where to download the compiler?

I would assume that its going to be the same compiler that you used for the standard Windows drivers. You would just need to change some of the c++ linker settings and target the right SDK versions.

This might help:

Since it looks like this may take awhile, I'll be done the initial proof for this project an a micro PC (http://fitpc.com/shop/product?id=121337) that run full Windows 10. Here is an example of the snap shot from my observatory. This was just a test and once the enclosure is fabricated it will be mounts away from the building.
