[KeilC51] 俄罗斯方块流水灯

Zhouzhi童鞋的作业，大家的思路差不多。。

#include <reg52.h>


void delay(unsigned int var){
    while(var--);
}
void main(){
   char idx1,idx2;
   unsigned char temp_P0 ;
   unsigned char Onthego ;
   unsigned char stack;
   temp_P0 = 0x00;
   stack = 0x00;
   for(idx1=7;idx1>=0;idx1--){
           Onthego = 0x01;
          for(idx2=0; idx2<=idx1;idx2++){
              temp_P0 =  stack;
              temp_P0 |= Onthego;
              P0 = ~temp_P0;
              delay(30000);
              Onthego *= 2 ;
              if(idx2+1==idx1){
                      stack |= Onthego;
              }
        }
    }
    while(1);
}
