CR95HF DLL compatibility issue?

Hi everyone,

I’m currently working with the CR95HF evaluation kit and looking into using the provided DLL (CR95HF.dll) for PC-side communication for a legacy project

However, the DLL seems to be compatible with 32-bit systems and I am looking for the 64-bit compatible version. As clarified in other discussions, the DLL needs to be recompiled for x64 compatibility. (CR95HF DLL x64 compatibility – is a 64-bit version available? | Community)

So my questions are:

  • Is there now an official x64-compatible version of the CR95HF DLL available?
  • Or is the recommended approach still to request/use the source code and rebuild the DLL for x64 systems?

Regards,

Aman

Hi Aman,

M24LR-DISCOVERY evaluation kit which includes the CR95HF transceiver board is Not Recommanded for New Design (NRND). The ST25R95/CR95HF is NRND too. See ST25R100/ST25R200 readers and STEVAL-25R200 evaluation kit for replacement.

The CR95HF.dll is an x32 DLL. In case you need to rebuild it for 64-bit systems, the source code can be provided to you.

Hi Brian, 

Thank you for your quick response. I am working on a legacy project that was setup on a 32-bit environment and I need to port it to a 64-bit version. 
 

If you can help me source code as you mentioned, it would be really helpful.

Thank you, 

Aman
