[KeilC51] 俄罗斯方块流水灯

Zhouzhi童鞋的作业,大家的思路差不多。。

 

 1 #include <reg52.h>
 2 
 3 
 4 void delay(unsigned int var){
 5     while(var--);
 6 }
 7 void main(){
 8    char idx1,idx2;
 9    unsigned char temp_P0 ;
10    unsigned char Onthego ;
11    unsigned char stack;
12    temp_P0 = 0x00;
13    stack = 0x00;
14    for(idx1=7;idx1>=0;idx1--){
15            Onthego = 0x01;
16           for(idx2=0; idx2<=idx1;idx2++){
17               temp_P0 =  stack;
18               temp_P0 |= Onthego;
19               P0 = ~temp_P0;
20               delay(30000);
21               Onthego *= 2 ;
22               if(idx2+1==idx1){
23                       stack |= Onthego;
24               }
25         }
26     }
27     while(1);
28 }
Code
