2、设计程序在液晶显示屏上显示计时时钟，精确到秒，形式为“时时：分分：秒秒”。
//常量定义
#define LCDDELAY 1
#define LCDCMDTURNON 0x3f
#define LCDCMDTURNOFF 0x3e
#define LCDCMDSTARTLINE 0xc0
#define LCDCMDPAGE 0xb8
2、设计一个按键“弹琴”的程序
#include "scancode.h"
#defineTIM*(int *)0x24
#definePRD *(int *)0x25
#defineTCR*(int *)0x26
#defineIMR*(int *)0x0
#defineIFR*(int *)0x1
#definePMST*(int *)0x1d
#define LCDCMDVERADDRESS 0x40
#define WAITSTATUS (*(unsigned int *)0x28)
// CTR扩展寄存器定义
ioport unsigned int port8000;
ioport unsigned int port8001;
ioport unsigned int port8002;
Xint.c程序：
#defineIMR*(int *)0x0
#defineIFR*(int *)0x1
#definePMST*(int *)0x1d
#define REGISTERCLKMD (*(unsigned int *)0x58)
ioport unsigned int port3002;
ioport unsigned int port3004;
TurnOnLCD();//打开显示
LCDCLS();//清除显示内存
CTRLCDCMDR=LCDCMDSTARTLINE;//设置显示起始行
CTRLCDCR=0;
for (;;)
{
CTRLCDCMDR=LCDCMDPAGE;//设置操作页=0
Delay(LCDDELAY);
CTRLCDCR=0;
Delay(LCDDELAY);
int i;
for(;;)
{
for ( i=0;i<4;i++ )
{
LBDS=~uLED[i];//正向顺序送控制字
Delay(64);//延时
}
for ( i=3;i>=0;i-- )
{
LBDS=~uLED[i];//反向顺序送控制字
Delay(64);//延时
}
}
}
void Delay(int nDelay)
{0x00,0x00,0x4C,0x92,0x92,0x92,0x7C,0x00}
};
main()
{
int i,nCount=0,nBW=0;
CTRGR=0;//初始化ICETEK-CTR
CTRGR=0x80;
CTRGR=0;
CTRLR=0;//关闭东西方向的交通灯
CTRLR=0x40;//关闭南北方向的交通灯

实验四、液晶显示器控制实验
实验内容：
1、验证ICETEK-VC5416-A评估板及教学实验箱实验指导书实验4.3.2的程序。
#define SPSA0 *(unsigned int *)0x38
#define SPSD0 *(unsigned int *)0x39
#define SPSA1 *(unsigned int *)0x48
#define SPSD1 *(unsigned int *)0x49
#define nMusicNumber 40
// LED宏定义
#define LBDS port3002
//延时和移位子函数声明
void Delay(int nDelay);
void ShiftToLeftAndRight(unsigned int nInit);
main()
{
unsigned int uLED[4]={1,2,4,8};//控制字，逐位置1: 0001B 0010B 0100B 1000B
{
nCountKey++; nCountKey%=8;
nLS^=0x40;
uWork=nCountKey|nLS;
LED=~uWork;//显示计数值
}
}
Xint.CMD程序：
-w
-stack 400h
-heap 100
-l rts.lib
MEMORY
{
PAGE 0:
VECT : o=80h,l=80h
for ( ii=0;ii<nDelay;ii++ )
{

}实验三、外中断实验
实验内容：
1、验证ICETEK-VC5416-A评估板及教学实验箱实验指导书实验3.4.2的程序；
2、修改实验程序完成按键中断控制的指示灯依次逐一点亮功能。
void Delay(unsigned int nTime);//延时函数
void TurnOnLCD();//打开显示
void LCDCLS();//清除屏幕显示内容
unsigned char ledkey[10][8]=
{
{0x00,0x00,0x7C,0x82,0x82,0x82,0x7C,0x00},//0
}
/*
int add(int a,int b)
{
return(a+b);
}
*/
实验二、指示灯实验
实验内容：
1、验证ICETEK-VC5416-A评估板及教学实验箱实验指导书实验3.1；
2、用纯汇编语言编程实现内容1；
3、比较两种程序的代码长度和效率。

ioport unsigned int port3002;
CTRLCDCMDR=LCDCMDVERADDRESS;//起始列=0
Delay(LCDDELAY);
CTRLCDCR=0;
Delay(LCDDELAY);
for ( i=0;i<8;i++ )
{
CTRLCDLCR=( nBW==0 )?(ledkey[nCount][i]):(~ledkey[nCount][i]);//屏幕左侧第1至8行第i列赋值port8002=0;// (赋值后当前操作列自动加1，所以不需设置)
