出现Selected text cannot be mapped to a symbol name警告问题
for (i = 0; i < uiRecvLen; i++)
lcd_Printf(“%02x “, ucRecvBuf[i]);
iRet = rfid_exchangedata(5, “\x00\xB0\x95\x00\x0a”,

for (j = 0; j < uiRecvLen; j++)
lcd_Printf(“%02x “, ucRecvBuf[j]);
函数原型:
int rfid_powerup(uint cardtype, uint *puiOutLen, uchar *pvOut);
int rfid_exchangedata(uint sendlen, uchar *psenddata, uint *precvlen, uchar *precvdata);
