Answer 1

首先，这代码不全……
其次，你需要解释哪些东西？这程序主体包含读卡头初始化、液晶初始化、显示时间/字符串等多种功能，基本上就是做个带液晶显示的读卡器。

追问

IC门禁 功能就是显示时分秒，液晶显示lcd1602
M500PcdConfigISOType( 'A' )
unsigned char idata UID[4],Temp[4]
unsigned char Count,Countf,Count1,Count2,Count3,Count4,Count5,C_flag
LCD1602_Disp_ZF(0x8a+0x40,"OK ",5)
Table[0]=UID[0]/100+0x30;
LCD1602_Disp_ZF(0x80+0x40,"Num: ",16)
uchar Dis_Table[8]="11:22:33"
不知道那几句定义了什么，还有就是上面几句含义，麻烦解释下
如果要完整代码我可以发给你
