这篇博客主要探讨了蓝桥杯比赛中的模块练习3，重点在于矩阵的处理。通过分析`main.c`，`juzhen.c`和`juzhen.h`这三个文件，博主详细讲解了矩阵计算的实现细节，包括矩阵的初始化、加减乘运算以及相关的算法优化。

main.c

#include <stc15f2k60s2.h>
#include <juzhen.h>


extern unsigned char display[];
extern unsigned char key;

void Timer0Init();


void main()
{

	Timer0Init();EA=1;ET0=1;
	P2=0XA0;P0=0X00;P2=0X1f;

	while(1)
	{	
		anjian();
	xianshi();

	
	}
}



void Timer0Init(void)		//2毫秒@11.0592MHz
{
	AUXR |= 0x80;		//定时器时钟1T模式
	TMOD &= 0xF0;		//设置定时器模式
	TL0 = 0x9A;		//设置定时初值
	TH0 = 0xA9;		//设置定时初值
	TF0 = 0;		//清除TF0标志
	TR0 = 1;		//定时器0开始计时
}
void shuma() interrupt 1
{
	unsigned char i;
	
	P2=0XE0;
	P0=0XFF;
	P2=0X1f;
	
	P2=0XC0;
	P0=1<<i;
	P2=0X1f;
