Anyone used the Velleman K8055 USB experiment
interface board?

I have been trying to figure out how to interface
my robot base and robot brain (laptop) and the
only thing on offer I could find in Australia was
the K8055 usb experiment interface board.

Previously I used the parallel port but my current
computer only has usb ports.

I have experience in soldering up such kits but
for some reason the test software that comes with
the kit fails to find the card.

I am using Windows Vista.

The demo code now works (bent pin on ic).

Has anyone used this board with their own c code?

Ah, that's will do it!  Good thing it was something simple like that vs the
more nasty problems like a burned out IC from some silly wiring mistake...

The card now works ok with the demo software.
The problem was a bent ic pin.

My next problem is how to use the dll to access the
card from plain C programs written with DevCpp.

I have not used dll's and the teach yourself C books
I have never covered the topic.

That points up the fact that if one is not an experienced
programmer, then stay away from boards that can only be accessed
via dll calls. Look for serial port based boards, either ones
that can be used with a USB to serial adapter, or ones that are
USB but appear as a virtural serial port. Programming is very
easy using many different programming applications.

My computer does not have a serial connection. It is not
that I haven't done a lot of programming I just haven't learned
the use of dll's because I haven't had any call for them in
the past. As it turns out I am now using two dlls with success
for a usb webcam and the above usb based K8055 card. All I
needed was some example code on how it was done.
