写单片机LCD少量汉字显示代码

好的，以下是一个基于STC单片机和16x2字符LCD的少量汉字显示代码，具体包括显示"你好"两个汉字：

#include <reg51.h>

#define LCD_DATA P0

sbit RS = P2^0;
sbit RW = P2^1;
sbit EN = P2^2;

void delay(unsigned int i)
{
    while(i--);
}

void lcd_write_cmd(unsigned char cmd)
{
    RS = 0;
    RW = 0;
    LCD_DATA = cmd;
    EN = 1;
    delay(100);
    EN = 0;
}

void lcd_write_data(unsigned char dat)
{
    RS = 1;
    RW = 0;
    LCD_DATA = dat;
    EN = 1;
    delay(100);
    EN = 0;
}

void lcd_init()
{
    lcd_write_cmd(0x38);
    lcd_write_cmd(0x08);
    lcd_write_cmd(0x01);
    lcd_write_cmd(0x06);
    lcd_write_cmd(0x0c);
}

void lcd_show_chinese(unsigned char addr, unsigned char *chinese)
{
    unsigned char i;
    lcd_write_cmd(addr);
    for(i=0;i<16;i++)
    {
        lcd_write_data(chinese[i]);
    }
}

void main()
{
    unsigned char chinese_hello[16]={0x18,0x18,0x18,0x18,0x18,0x3C,0x66,0x66,0x7E,0x00,0x7E,0x66,0x66,0x7E,0x00,0x00};
    lcd_init();
    lcd_show_chinese(0x80, chinese_hello);
    while(1);
}

其中，`lcd_write_cmd`和`lcd_write_data`分别用于向LCD写入指令和数据，`lcd_init`用于初始化LCD，`lcd_show_chinese`用于显示汉字，`chinese_hello`数组存储了"你好"两个汉字的点阵数据。在`main`函数中，先调用`lcd_init`初始化LCD，然后调用`lcd_show_chinese`显示汉字，最后进入死循环。
