时序, unsigned, CD, ST, LCD
求 指令和数据的程序。   望高手指教下我写的：
#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit rs=P2^4;
sbit rw=P2^5;
sbit ea=P2^2;
sbit psb=P2^1;
void write_com(uint com);
void write_data(uint dat);
void delay(uchar z)
{
uchar x,y;
for(x=z;x>0;x--)
  for(y=110;y>0;y--);
}
void init ()
{
psb=1;
rw=0;
write_com(0x01);
write_com(0x0f);
}
void write_com(uint com)
{
ea=0;
rs=0;
rs=1;
P0=com;
ea=1;
delay(1);
ea=0;
}
void write_data(uint dat)
{
ea=0;
rs=1;
rs=0;
P0=dat;
ea=1;
delay(1);
ea=0;
  
}
void main ()
{
init();

}
/*请教下 怎么调试出光标来。我的源程序是按照只写不读，所以RW一直拉低。。还有我看了源程序 貌似P2.6口不是始能端？
在时序图中,EA端不是要拉高才能读到数据吗？为什么源程序是拉低？为什么他要设置2个形参？

开发板附的源程序是这么样的：

#include"reg52.h"
#define WINDOW_XADDR_START 0x0050 // Horizontal Start Address Set
#define WINDOW_XADDR_END 0x0051 // Horizontal End Address Set
#define WINDOW_YADDR_START 0x0052 // Vertical Start Address Set
#define WINDOW_YADDR_END 0x0053 // Vertical End Address Set
#define GRAM_XADDR      0x0020 // GRAM Horizontal Address Set
#define GRAM_YADDR      0x0021 // GRAM Vertical Address Set
#define GRAMWR        0x0022 // memory write

sbit CS=P2^2;  //片选
sbit RES=P2^1;  //复位
sbit RS=P2^4;  //数据/命令选择
sbit RW=P2^5;
                    //数据口使用P0
