When calling (from C#):ST25R391xNativeMethods.iso15693Initialise(Handle, 0, false)I am getting an error response that decodes to "No Memory". I have had this error before when supplying a buffer that was too small for the response, however, no data i...

I recently purchased a STEVAL$25R3916BA evaluation kit because I was given to understand that this had a 64-bit DLL available, whereas the older 3911-based kit didn't.However as I have started to write code based on the DLL, I have found it is actual...

I'm working on code that uses the Windows DLL that came with the "Discovery kit for the ST25R3916B" and ST25DV04K tags.The tag is hosted within an embedded system, and I'm working on Windows PC software that communicates with the EVAL boards/reader.I...

attn @Brian TIDAL et alI have yet another issue I don't understand. I have code that I have run against two similar products using the same ST25DV04K tag. The products differ in that one has a slower CPU clock. On the product with the faster clock, m...

Dear all,I'm attempting to use fast transfer mode with a ST25RDV04K type 5 tag and the STEVAL board for 3916B. I know this theoretically works because I have some Java code that is able to do it successfully, but I'm porting the code and I keep runni...

First, apologies for my lack of information.You have presumed correctly. I am developing a Windows app in C# and using the DLL supplied with the ST25R3916B Discovery Kit.That's an interesting thought. So if I understand correctly, you think my receiv...

OK good, thanks. That's good to know.What I'm seeing in my code is that at some point I don't get a reply, and often a nonsensical error code such as "no memory". I _presume_ that is the clue that interface arbitration has occured. What would I need ...

That did it - thank you Brian :thumbs_up:

Would you mind helping me a bit further? It would be helpful if you could walk me through how to understand a specific example, for example, how to present a password to unlock writing to user memory.There is nothing in the DLL that refers to a passw...

Thanks for your reply. That is actually quite helpful, I didn't know the firmware source was available. The software support for these devices is actually pretty terrible unless you happen to be using Java (which we are not). As a complete novice to ...
