I recently bought a Velleman PVM110N. By having to my IUT exactly the same, so I took the dll, the header and the library that goes with it.
I want to program in C.
I set code compiler options for Blocks, and Linkers.
The program is already done and already checked, it works. The problem is that he says that access to the card is impossible …
Knowing that in my IDE everything is good, and that my program too, that the riders are well set to choose the address of the card, I do not understand … for me it’s a DLL pb but I have put with the same file, in Windows, in System 32 and in Code Blocks even to be on, and its access to the IDE designates one of them …
Please help me debug the situation …
Thank you very much in advance!
PS: Here is the program in C:
// TEST PROGRAM FOR USB CARD K8055 (flashing output 1)
int main ()
test = OpenDevice (3);
if (test! = 3)
puts (“opening USB card impossible!”);
printf (“USB card% d open \ n”, test);
while (kbhit () == 0);
printf (“USB card% ld closed \ n”, test);
I just want to add that…I’ve got 2 computers, the first is on Win8 and the second on Win7. On the first, with my program, it is written that it’s not possible to open the USB; With the Win7 computer, it’s written that it’s open but the program doesn’t work whereas it worked at my school…
