CR95HF DLL x64 compatibility – is a 64-bit version available?

[MoBH]

Hi everyone,

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

From the documentation and software packages I understand that a DLL is provided to interface with the CR95HF demonstration board (). However, it seems this DLL was originally built for older environments and is typically installed in x32 systems, which suggests it may be a 32-bit library.

I searched the community and found a previous discussion where someone asked about x64 compatibility ( Solved: CR95HF DLL for x64 - STMicroelectronics Community ) and was provided with source code instead of a precompiled DLL.

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?

If rebuilding is required:

• Is there any official guidance or updated project for generating a 64-bit version?

Thanks in advance for your help!

Hi,

the CR95HF RF transceiver Demonstration Board is part of the M24LR-DISCOVERY evaluation kit. This kit is Not Recommended for New Design (NRND). The ST25R95/CR95HF is also in NRND status. The existing tools and firmware are still available. The source code of the CR95HF DLL 32-bits version can be provided if you want to rebuild for x64. Adding  @cristianc72  to provide information about port to x64.

I recommend moving to ST25R200 reader and its STEVAL-25R200SA discovery kit.
