Reading/Writing specialty register with ST25R3911B DLL files

Hi All, 

I having been using the st25R3911B-disco board for the past several months as a development tool for a project using the ST25DV chipset. Up until now I have really only had to use the iso15693writ/readblockblock functions that I saw in the cpp example project. Now however I need to write to and read from special registers on the tag i am communicating with, such as the dynamic registers on the ST25DV chip. Its not obvious to me which functions from  ST25R3911B header file I need to use to do this, can someone point me in the right direction? 

 

Thanks,

Patrick

    Hi Patrick,

    iso15693TxRxNBytes function can be used to send custom commands such as Read Configuration or Read Dynamic Configuration to a ISO15693 tag. Just format the content of your buffer according to the command specification in the tag datasheet and then sent it with iso15693TxRxNBytes.
