Just got the K8055 assembled, and planning to use it on a windows 7 64 bit system.
There are numerous posts on the topic of getting K8055 running for the first time, and between the softs provided with the kit on the VPCD4 CD-ROM and the softs available for download on the website, I don’t know which step to take first.
So, since Win7 has become the new standard, I think it could be useful to write a “step-by-step” guide and publish it here for all new users. What do you think ? Anyway, it could be for me.
What do I do now? What do I have to install before plugging in the K8055 for the first time ?
Thanks for your answer, and for considering my suggestion.
You can just plug in the card without installing anything before it.
The K8055 is a HID class device. The driver is included to the Windows 7.
Then you may download these two packages and run the demo software using the latest DLL version 3.0.2:
Software DLL (Rev 3.0.2)
supports Windows Vista, VC++ version and executable examples
Software DLL Rev 2
older DLL with examples and source code (source can also be used with DLL rev 3)
This package includes also the documentation of the use of the DLL.
OK, I connected, LD8 blinked, and after about 10 or 12 seconds (time for the system to install the driver), it went off. Everything seems allright so far.
I then copied the K8055D.DLL (version 3.0.2.0) to the Windows\system32, and tried to run the K8055_Demo.exe program, to test the card.
The window opens as expected, but when I click on the “Connect” button (with default adress 0, that is SK5 and SK6 checked, and jumpers in place on the board), I receive an execution error 53: Cannot find k8055d.dll
I rebooted the PC, just in case, but it didn’t help.
Then I tried by moving the K8055D.DLL to the Windows folder: and then it worked !
I didn’t change any setting in the way K8055_Demo.exe is executed (no change in “compatibility” or “run as…”), and I didn’t recompile the program either.
I just wanted to post this so that if other users experience the same difficulty, they can find a quick answer.
I will now go on with some development with VB.
Thanks for your help, and please continue to provide us with the high quality kits we know.
Indeed, in Windows 7 x64 the DLL must be either in Windows folder or in the folder of the .exe file.
You may get this kind of error message when running the Visual Basic 2008 program:
“[color=#BF0000]An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)[/color]”
