rc522讀寫，復制，修改密碼，所有扇區內容修改

ID:173447 · 發表于 2018-8-10 13:43

//讀寫扇區的例子：//全部扇區數據塊可單獨讀寫，也可全部扇區同時讀寫，可以復制全部扇區的內容，也可以重新賦值全部扇區的內容
#include <SPI.h>
#include <RFID.h>

RFID rfid(53,49); //D53--讀卡器MOSI引腳、D49--讀卡器RST引腳//2560板子
#define qh    43//功能切換讀取
#define d    44//LED燈，滅代表讀狀態，亮代表寫狀態
char b=0;
//4字節卡序列號，第5字節為校驗字節
unsigned char serNum[5];
//寫卡數據,45為數據塊數量，16為長度
//數據塊是1-15扇區相加，每個扇區3個數據塊故3*15=45；0號扇區固定不能改
