实验七 设计性实验1 实验题目： 简易万年历2 功能说明： 2014年06月12日 12 : 00 : 00 30C 液晶屏上显示即时的日期、时间和温度，且日期和时间可调节。3 编程思想：编程采用模块化思想，将程序分为几个模块，即液晶屏模块、数字温度传感器模块、定时器模块等。定义端口，使日期和时间各位可调。4 程序清单：LCD.c文件#include #include unsigned char code number_X= /宽x高=8x16,纵向字节倒序 0x00,0xE0,0x10,0x08,0x08,0x10,0xE0,0x00, /0 0x00,0x0F,0x10,0x20,0x20,0x10,0x0F,0x00, 0x00,0x10,0x10,0xF8,0x00,0x00,0x00,0x00, /1 0x00,0x20,0x20,0x3F,0x20,0x20,0x00,0x00, 0x00,0x70,0x08,0x08,0x08,0x88,0x70,0x00, /2 0x00,0x30,0x28,0x24,0x22,0x21,0x30,0x00, 0x00,0x30,0x08,0x88,0x88,0x48,0x30,0x00, /3 0x00,0x18,0x20,0x20,0x20,0x11,0x0E,0x00, 0x00,0x00,0xC0,0x20,0x10,0xF8,0x00,0x00, /4 0x00,0x07,0x04,0x24,0x24,0x3F,0x24,0x00, 0x00,0xF8,0x08,0x88,0x88,0x08,0x08,0x00, /5 0x00,0x19,0x21,0x20,0x20,0x11,0x0E,0x00, 0x00,0xE0,0x10,0x88,0x88,0x18,0x00,0x00, /6 0x00,0x0F,0x11,0x20,0x20,0x11,0x0E,0x00, 0x00,0x38,0x08,0x08,0xC8,0x38,0x08,0x00, /7 0x00,0x00,0x00,0x3F,0x00,0x00,0x00,0x00, 0x00,0x70,0x88,0x08,0x08,0x88,0x70,0x00, /8 0x00,0x1C,0x22,0x21,0x21,0x22,0x1C,0x00, 0x00,0xE0,0x10,0x08,0x08,0x10,0xE0,0x00, /9 0x00,0x00,0x31,0x22,0x22,0x11,0x0F,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, / . 0x00,0x00,0x00,0x00,0x00,0x60,0x60,0x00, 0x00,0x80,0x80,0x80,0x80,0x80,0x80,0x00, /- 0x00,0x01,0x01,0x01,0x01,0x01,0x01,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, /nop 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0xC0,0xC0,0x00,0x00,0x00, /： 0x00,0x00,0x00,0x30,0x30,0x00,0x00,0x00;/* *函数：void LCD_WriteCommandE1(unsigned char com)*功能：写指令代码子程序(E1)*/void LCD_WriteCommandE1(unsigned char com)while(CRADD1 & 0x80);CWADD1 = com;/*函数：void LCD_WriteCommandE1(unsigned char com)*功能：写显示数据子程序(E1)*/void LCD_WriteDataE1(unsigned char dat)while(CRADD1 & 0x80);DWADD1 = dat;/*函数：void WriteCommandE2(unsigned char com)*功能：写指令代码子程序(E2)*/void LCD_WriteCommandE2(unsigned char com)while(CRADD2 & 0x80);CWADD2 = com;/*函数：void WriteCommandE2(unsigned char com)*功能：写显示数据子程序(E2)*/void LCD_WriteDataE2(unsigned char dat)while(CRADD2 & 0x80);DWADD2 = dat;/*函数：void LCD_Init()*功能：LCD初始化程序*/void LCD_Init()LCD_WriteCommandE1(0xe2);LCD_WriteCommandE2(0xe2);LCD_WriteCommandE1(0xa4);LCD_WriteCommandE2(0xa4);LCD_WriteCommandE1(0xa9);LCD_WriteCommandE2(0xa9);LCD_WriteCommandE1(0xa0);LCD_WriteCommandE2(0xa0);LCD_WriteCommandE1(0xc0);LCD_WriteCommandE2(0xc0);LCD_WriteCommandE1(0xaf);LCD_WriteCommandE2(0xaf);/*函数：void LCD_Clear()*功能：清屏*/void LCD_Clear(void)unsigned char i,j;for(i=0;i4;i+)LCD_WriteCommandE1(i+0xb8);LCD_WriteCommandE2(i+0xb8);LCD_WriteCommandE1(0x00);LCD_WriteCommandE2(0x00);for(j=0;j0x50;j+)LCD_WriteDataE1(0x00);LCD_WriteDataE2(0x00);
