51單片機(jī)做的8X8點(diǎn)陣斜線代碼

本想整個8X8點(diǎn)陣左右流水燈，從上到下的代碼，結(jié)果參數(shù)搞錯啦，整成斜線，經(jīng)仔細(xì)檢查發(fā)現(xiàn)是代入的參數(shù)不對，代碼如下。
#include<reg51.h>
#define ROW P2
#define COL P1

void delay(unsigned int time)
{unsigned int i,j;
for(i=0;i<time;i++)
for(j=0;j<120;j++);}

void display(){
unsigned char i,j;
unsigned char row_pattern[16]={
0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80,
0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01};
unsigned char col_pattern[16]={
0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80,
0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01};

for(i=0;i<16;i++){
ROW=row_pattern[i];
for(j=0;j<16;j++){
COL=~col_pattern[j];//改變[]里的j為i 就會出現(xiàn)8X8點(diǎn)陣燈從上到下斜著走來回
delay(100);
}}}

void main(){
while(1){
display();}}
