ANT Forum

Hello,

I saw this older thread, http://www.thisisant.com/forum/viewthread/3795/

and it mentions there are no version of the ANT_DLL.DLL for 64 bit

I understand 32 bit windows apps work fine under 64 bit, but if an application itself is 64 bit obviously it cannot use a 32 bit DLL.

Has any one compiled it under 64 bit? How about the other 2 DLL's,

DSI_SiUSBXp_3_1.dll, DSI_CP210xManufacturing_3_1.dll ?

I guess we would need 64 versions too?

The only alternative I would see is create a 32 process to communicate via Ant_DLL.dll and have the 64 bit application communicate with it using some IPC (interprocess communication). But that is quite a bit more complex than having a 64 bit version of Ant_Dll.dll.

Any other options?

Thanks,

Michel

     

Your assumption is correct (32 bit DLLs can't be loaded into a 64 bit application).
Another solution would be: compile your application as a 32 bit app. Is there a read need to have a 64 bit application, e.g. huge address space, loading other DLLs that are only available in 64 bit versions, ... ?
     

I agree 32 bit apps are fine, and I don't see an issue with them. But the reality is many users are expecting 64 bit apps on their 64 bit OS. It's a matter of perception.

Forcing an entire application to be 32 bit just because the ANT interface is only available in 32 bit is quite a limitation nowadays. It would nice if the ANT_DLL library would be updated to 64 bits.

Thanks,

So it's more a psychological matter than a technical one?

Well, the source code for ANT_NET.dll and ANT_DLL.dll are available as part of the "ANT Windows Library Package". However, the two driver DLLs DSI_CP210xManufacturing_3_1.dll and DSI_SiUSBXp_3_1.dll are only available as binaries, probably supplied by the chip designers (Silicon Labs).
So to my best knowledge you won't get a full set of 64 bit DLLs and would have to build your IPC solution.
