Unable to load DLL 'mpusbapi.dll'
PostPosted: Sun Jun 25, 2006 3:44 pm     Reply with quote

When I build PicUSB in Visual C# 2005 Express, then run it, I get an exception:
"Unable to load DLL 'mpusbapi.dll': The specified module could not be found. "
It seems to me that I read something about this in another post, but couldn't find it. Sad
Can you help me?

"Unable to load DLL 'mpusbapi.dll' solved

Oops! Embarassed
mpusbapi.dll was not in folder bin\Release (where my output application goes).
Copied it in there, as Mat said, and now it is working.
The SW is always right, no?

Hi all,

I´ve updated this article and I´ve published on my webpage an example called PicWinUSB which is possible to make your own apps based on Windows Vista using WinUSB in Bulk USB mode Transmision. Check here:

Do you have a version that doesn't require .NET? or possibly any instructions that would help me make a version for Delphi?

thanks

Hi ratgod,

Actually this article (PicWinUSB) is only made in VC#, but it can be migrated to another language like PicUSB, originally in VC# was migrated to VC++, VB, Delphi, Labview. (Take a look at PicUSB (VC#) and PicUSB Stuff (PicUSB_Delphi) articles in my webpage). I´ve seen a C++ version of a WinUSB project. So if you take this Source Code (PicWinUSB) and compare it with older articles (PicUSB: VC# to Delphi) you will take the possibility to migrate to Delphi.

Good luck and Best Regards Smile

ps: Sorry for my complex way to express myself in english ^^

You still can use mpusbapi.dll and that is open source in my website. Donation is 5€, same that you pay for a cigarette box ;) If you are going to be poor if you pay that... tell me and I´ll send it to you free ... I think anyone can offer his 'intellectual properties' as he wants. And at the same way I did it, you can do it... I´m totally sure. You only need to invest your time... if you have no time, then make a donation for time spend from other people. Easy, it isnt?

Best regards

I've had a good play with the PICusb delphi port. it all works fine for me but does anyone know how to make the delphi side receive data streamed from the PIC without requesting it?

I want to stream data from a CANbus to a laptop via USB
I tried CDC but the software on the windows side always comes out flakey.

anyone have any ideas?

I only use delphi on the laptop btw

Dear Hobby PIC,
I just used your code and modified it too, its running good. Thanks.
But I have a problem, when I transmit a file from PC it is received at PIC18F2550, the speed of communication is very slow, it takes seconds to transmit Kbs. Please suggest what might be the issue?
