完成SD卡和TFT屏的底层程序，等不及了，先刷几张图看看先

WAV播放和图片浏览视频及目前所有源码在30楼.
按键测试~~

按键测试视频ourdev_691282QA2Y0T.avi视频文件大小:15.62M) (原文件名:keytest.avi)
目前按键测试有点小问题，那就是left键和A键发生串键，A键弹起的瞬间left键会有动作（在上面测试视频可以看到）。键盘是用74LS165弄的，left键对应下图key1，A键对应下图key8.估计是软件问题。大家帮分析下~~
按键部分的电路图 (原文件名:key.jpg)
这是按键部分的代码
#include"KEY_HC165.h"
#include"reg52.h"
sbit KEY_PL=P1^4;
sbit KEY_CLK=P1^5;
sbit KEY_OUT=P1^6;
uchar KeyVal;
void KeyInit(void)
{
TMOD=0x01; // T0工作于模式1：十六位定时器
TH0=0; //计数器赋值
TL0=0;
ET0=1; //T0中断允许
EA=1; //总中断允许
TR0=1; //开定时器
KEY_CLK=1;
KEY_OUT=1;
KEY_PL=1;
KeyVal=0;
}
void delaya(void)
{
xdata uint i=30;
while(i--) ;
}
void time0_interserve(void) interrupt 1 using 1 //T0的中断编号为1，使用第一组寄存器
{
xdata uchar i;
TR0=0; //关定时器
KEY_PL=0; //置数
delaya();
KEY_PL=1;
delaya();
for(i=0;i<7;i++)
{
if(KEY_OUT) KeyVal=KeyVal|0x01;
KeyVal=KeyVal<<1;
KEY_CLK=0;
delaya();
KEY_CLK=1;
delaya();
}
if(KEY_OUT) KeyVal=0x01;
delaya();
TH0=0;
TL0=0;
TR0=1; //开定时器
}
