Hello!I am trying to read some blocks from a iso 15693 tag. I can do it with Android without any problem. But when I try to do it with iOS I always receive the response [255,255]. What does it mean?For example:22 33 E0 02 51 00 02 4E BE 55 08 00 32 0...
I'm using FP-SNS-SMARTAG1, but I can't write strings correctly with code, and I can't write anything, what should I do? while (1) { /* Wake Up due to RTC timer */ if(WakeUpTimerInterrupt) { WakeUpTimerInterrupt =0; WakeUpTimerCa...
在目前的项目中，已经实现ST25R3911B作为主机，ST25R3916B作为从机，使用透明模式收发数据。我希望可以在透明模式中使用负载调制，以实现自定义的协议，我尝试使用ST25R3916B在透明模式中使用负载调制，但是没有成功，现象是将位targ=1之后，ST25R3916B的MISO没有收到主机的任何数据，且没有办法使用MOSI发送任何数据。请问ST25R3916B如何在透明模式中使用负载调制？位targ需要如何配置？Here is the machine translation:In t...
