Seeking guidance using Windows SuperCAN app and DLL

[brunjc337]

Hi, I have built a CAN bus Analyzer software that targets Kvaser, Vector and PEAK hardware, and would like to include SuperCAN support. I am very interested and enthusiastic about SuperCAN. I've been researching SuperCAN on and off for several months. Each time I research the subject, I seem to answer questions I previously had, and solve the problems that I have come across, as the information generally seems to be here in the repo.

Currently, I am able to build and deploy firmware to a SAME54 XPlained board. I am trying to understand the SuperCAN App and driver. I have been able to successfully build each project in the solution, however I have the following issue:

1.) trying to install the DLL using cmd regsvr32 (error -- "The module "supercan64.Dll" was loaded but the entry point DllRegisterServer was not found. Make sure that "supercan64.dll" is a valid DLL or OCX file and try again")

I realize the high probability I have overlooked the documentation. If that's the case, can you please kindly point me in the direction on how to run the app so I can understand the driver through the example SuperCAN App? If not, I would very much appreciate support in how to get it running, and would be happy to provide support to the project if needed, as well.

Thank you!!

Thank you for your kind words. I am glad you find the project helpful.

Currently, I am able to build and deploy firmware to a SAME54 XPlained board. I am trying to understand the SuperCAN App and driver. I have been able to successfully build each project in the solution, however I have two issues: 1.) trying to install the DLL using cmd regsvr32 (error -- "The module "supercan64.Dll" was loaded but the entry point DllRegisterServer was not found. Make sure that "supercan64.dll" is a valid DLL or OCX file and try again")

The COM server is located in the supercan_srv.exe binary. That's the one, you need to register. There are two ways to use SuperCAN devices from an application. Exclusively, through supercanXX.dll or shared with other apps through the COM server.  Have a look at the demo app, both ways are implemented there (option --shared).

2.) running/debugging the actual SuperCAN App-- do I need a device connected before I run the app?

No, you don't. The search (scan) for devices will simply come up empty.

Thank you for your speedy response!

I was able to get the Supercan App to find my Supercan Device (on XPlained SAME54 board) successfully. I will continue to research tx/rx from the app, evertything from there on out seems straightforward enough.

As for the DLL/COM Server, is it correct that --shared uses the SRV/CPP COM Server, and the --single uses the DLL? and the DLL is runtime loaded, i.e. does not have to be installed?

Thanks again for your input!

That's right on both accounts.
