這個(gè)程序真的花了我好長的時(shí)間調(diào)試，終于寫好了，大家可以看看我的密碼鎖，有點(diǎn)花哨嘔??！

下面是密碼鎖簡約版本：

main.c

#include

#include"12864.h"

#include"keyscan.h"

#include"baojin.h"

uchar mima[5]={1,2,3,4,5};

main()

{

uchar length,i,flag,inputtimes,flagkaimeng;//tempê??ü??μ?áùê±±?á?

uchar itouch,flaggaimima;//ó?à′???????yê?è?μ??ü??μ???êy

uchar mimatemp[5];

init_12864();

lcd_pos(0,2);

write_string("welcom!!");

delay1ms(2);

lcd_pos(1,0);

write_string("PSW:");

write_cmd(0x0f);//′ò?a1a±ê

f3:

while(1)

{

i=0;

if(inputtimes>=1)//ê?è?′í?óoóμ??￠μ÷?êìa

{

lcd_pos(1,2);

write_string(" ");

lcd_pos(1,2);

}

while(1)

{

num=keyscan();

if(num!=0xff)

if(num==15)//?¨ò??aè·è?

lcd_pos(1,2);

write_string(" ");

lcd_pos(1,2);

if(i==-1)//±ü?a?à′?°′???ì3ébug

}

}

}
