使用STM32控制NXP的NFC读�?�器芯片CLRC663读写ST公�?�的NFC标签芯片M24SR64的问题? 现在项目上�?求把NXP公�?�的 CLRC663芯片用STM32�?�控制读写�?作。 有没有大佬�?�过这方�?�的移�?啊，

HELLO DaLao，

May I ask you a question about how can I shoud use clrc663 to read 14443a tag (m24sr64) by a wireless way?

Now,I can read and write MIFARE tag succesful, but can't do with 14443A tag?

This do sucessful:

status = phpalI14443p3a_ActivateCard(&I14443p3a, NULL, 0x00, bUid, &bLength, bSak, &bMoreCardsAvailable);

This failed:

PH_CHECK_SUCCESS_FCT(status, phKeyStore_SetKey(&Rc663keyStore, 0, 0,PH_KEYSTORE_KEY_TYPE_AES128, &Key[0], 0)); this function return 0x201.

And I find that PH_KEYSTORE_KEY_TYPE_AES128 is not supported by this software lib, in that function the case of "PH_KEYSTORE_KEY_TYPE_AES128" is EMPTY!

Finally, may I ask if the clrc663 can read/write with 14443a tag produced by other company?

And, wether the software lib is complete to support to read/write with 14443a tag?

Tanks a lot,

have a nice day!

我现在就是读出�?�TAG的UID，但是无法匹�?密�?密钥。�?知�?�RC633对支�?的NFC芯片厂家有没有�?制。现在读写NXP公�?�的MIFARE�?�没有问题，但是我现在想用的TAG是ST公�?�的M24SR，读出UID之�?�始终�?能读写。

想问问是�?是就算TAG没有密�?，也需�?进行密�?密钥匹�?�?能进入读写�?程啊。我试了�?用密�?密钥匹�?函数，读写函数也执行�?了啊。

此外我想问问NXP的CLRC663和ST的M24SR兼容�?�

May I ask if this kind of reader can read/write with this kind of tag?

thanks a lot! ​

​Dear customer,

according to the CLRC663 reader datasheet, it should be capable of reading any 14443-A tag correctly. M24SR Is  based on the ISO/IEC 14443-A specification so there should not be any problem for the M24SR product to be read from CLRC663.

Device activation in 14443-A does not require an AES128 encryption/decryption, so it is possible that the functions that are referred to above are not the proper functions to be called in this case. I advise to contact the customer support of the CLRC663 reader for getting more information.

Or please refer to our STMicroelectroncis readers' product line which are fully compatible with M24SR.

Have a good day.

Regards
