In the documentation for IowKitCloseDevice it state that:
void IOWKIT_API IowKitCloseDevice(IOWKIT_HANDLE devHandle);
...
As of dynamic library version 1.4 the function ignores the parameter completely. Since it closes all
opened IO-Warriors anyway, there is no real need to check if the parameter ...

Is it possible to access different IOWarriors from separate programs on the same machine?

thanks, the examples where helpful, is there a version of iowkit.lib in OMF format as i am using Borland Turbo C++ and I think that converting the .lib from COFF to OMF may have impaired the functionality. I can get it to work as i want in VC++ 2010 but i need to use it with borland.

Hi,
Im have trouble trying to use multiple IOW24's, i have two connected and am trying to acquire the serial numbers from each device, i used the SimpleIIC example as a guide but both devices are returning the same number.
WCHAR s[9];
IOWKIT_HANDLE ioHandle;
IOWKIT_HANDLE handles[16];
IOWKIT ...

I have read through the data sheet but it didn't help much, it seems more directed to the electrical side of things, and I couldn't get the SimpleIo example to work, I simply want to write 1 byte to my device:

DeviceId = 40;
Address = 1;
Data = 0 - 255;

i have been using the following code:
for ...

After tracing through the source code for Simple-IIC i got it work with this code:

IOWKIT_SPECIAL_REPORT report;
memset(&report, 0, IOWKIT_SPECIAL_REPORT_SIZE);

report.ReportID = 2;
report.Bytes[0] = 196;
report.Bytes[1] = 80;
report.Bytes[2] = 40;
report.Bytes[3] = 01;
report.Bytes[4 ...

I downloaded the Visual Studio 2010 trail and traced through the code, when using IOWKIT_SPECIAL_REPORT i noticed that report.Bytes[2]-[4] contain my 40,1,255. But what do ReportID, Bytes[0] and Bytes[1] represent?

report.ReportID = 0x02;
report.Bytes[0] = 0xC1 + send;
report.Bytes[1] = adresse;

It compiles with this but still nothing happening.

I am trying to use the device to control a light source,
to turn the light on I need to send 255 to it so I entered this to the example in hex and it worked, so the address is correct, I would step through the example source code to find my answer but I am using Visual Studio Express and cannot ...

I am having trouble trying to write to a device, i tried using the example in the Help Doc-


ioHandle = IowKitOpenDevice();
ULONG numPipe=1;
IOWKIT24_IO_REPORT report;
report.ReportID = 40;
report.Value = 255;
ULONG rc=IowKitWrite(ioHandle,numPipe,&report,IOWKIT24_IO_REPORT_SIZE ...

Thanks for the help, I included windows.h and it worked.

I have started trying to use the sdk, but when I try to compile my code about 140 errors are returned from iowkit.h, I am running VC++ Express 2008, I have included the .lib file in the linker and added the .lib, .h and .dll files to my project directory, any help getting around this would be great ...
