STM32和PN5180的NFC开发包

STM32和PN5180的NFC开发包如果开发者对于本文件有需要的可以参考。
STM32和PN5180的NFC开发包，可实现ISO15693和ISO14443A协议读写卡。

uint16_t ATQA = 0;
uint16_t Length = 0;

uint8_t Command[3];

Command[1] = 0X07; /* LSB先发，只发送0X52的7bits */
Command[2] = 0X52;
if (ISO14443_CommandSendAndRecvData(Command, sizeof(Command), Buffer, &Length) == 0)
{

{
ATQA = (Buffer[1] << 8) | Buffer[0];
}
}
// printf(" ----REQA");
return ATQA;
