ST25R3911B DISCO

[John63]

Hi,

I currently have a LabVIEW 32 bit application that uses the ST M24LR-DISCOVERY evaluation kit via the CR95HF.dll, and now have a need to update this application to use the ST ST25R3911B DISCO DISCOVERY kit via the ST25R3911DISCOComm.dll

Is there and documentation regarding the ST25R3911DISCOComm.dll available

Ideally a xRef document between CR95HF.dll and ST25R3911DISCOComm.dll so that I can match the correct function names.

Regards

John

Hi John63, 

unfortunately there is no cross-reference document. The two DLLs were developed fully independently (even inside different companies).

For ST25R3911B-DISCO the DLL functions are mostly direct forwards from the functions with the same name inside the firmware. In the firmware source you will find more detailed documentation.

Hi,

I cannot seem to find the equivalent commands for the ST25R3911DISCOComm.dll

for the CR95HF.dll In LabVIEW I am using 

Function Name: CR95HFDLL_USBconnect

Function Prototype: int32_t CR95HFDLL_USBconnect(void );

Function Name: CR95HFDll_Select

Function Prototype: int32_t CR95HFDll_Select(CStr Command, CStr Answer);

Function Name: CR95HFDll_SendReceive

Function Prototype: int32_t CR95HFDll_SendReceive(CStr Command, CStr Reply);

Which commands do I need to use with the ST25R3911DISCOComm.dll

This is for ISO 15693.

Regards

Hi John,

For the mentioned functions you will need to use something like the following functions (in order):

• GetST25R3911()
• iso14443aInit(), iso14443bInit(), iso15693Init()
• txrxBytes()

The existing project shows how to use these functions.

Alternatively you could also use the more modern functions rfalSetMode(), rfalFieldOnAndStartGT(), rfalStartTransceive(), rfalGetTransceiveStatus().
