CLRC663 library use question

[lisong6080]

Hello，

           Currently，I use NFC Reader Library for CLEV663B on linux  platform. I   use

"phpalI14443p3a_Sw_Init " fuction   and  "phpalI14443p3a_Sw_ActivateCard"  fuction,but it has a probelm.When both of them have been called in same funtion，the card can be active.When the two fuction are been  separated into unsame  funtion,the NFC Reader Library will point out  segmentation fault. The "phpalI14443p3a_Sw_DataParams_t" Structure is a global variable.

       Can you tell me how I can solve this probelm? I use "SW3693"  NFC Reader Library.

       Thank you very much!

Hi LiSong,

Would you please specify NFC Reader Library version number? and how did you implement "phpalI14443p3a_Sw_Init " fuction   and  "phpalI14443p3a_Sw_ActivateCard"  fuction in two different APIs? can you make sure "phpalI14443p3a_Sw_ActivateCard" is always called after "phpalI14443p3a_Sw_Init " ?

Thanks for your patience!

Have a great day,
Kan Li

Hi Kan Li,

              Thanks for you replay, I find some buffer(Tx buffer,Rx buffer) must be defined global variable.
