本任務(wù)是用單片機(jī)實(shí)現(xiàn)液晶顯示演示效果如圖所示。通過(guò)編程，學(xué)會(huì)在單片機(jī)上實(shí)現(xiàn)液晶顯示控制方法，以及不同數(shù)據(jù)顯示的程序編寫方法。
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）
單片機(jī)源程序如下:
- #include "LCD_12864.h"
- #include <stdio.h>
- extern void cls();
- extern uchar LCD_Initialise();
- extern uchar LCD_Write_Command(uchar cmd);
- extern uchar LCD_Write_Command_P2(uchar cmd,uchar para1,uchar para2);
- extern uchar LCD_Write_Data(uchar dat);
- extern void Set_LCD_POS(uchar row,uchar col);
- extern uchar code LCD_WIDTH;
- extern uchar code LCD_HEIGHT;
- sbit S1 = P1^0;
- sbit S2 = P1^1;
- uchar code ImageX[] =
- {
- 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
- };
- void main()
- {
- uchar i,j,m;
- uint k,x;
- LCD_Initialise();
- Set_LCD_POS(0,0);
- cls();
- while(1)
- {
- if(S1!=0)
- {
- LCD_Write_Command_P2(LC_GRH_STP,0,0);
- for(i=0;i<LCD_HEIGHT;i++)
- {
- Set_LCD_POS(i,0);
- LCD_Write_Command(LC_AUT_WR);
- for(j=0;j<LCD_WIDTH;j++)
- {
- m = ImageX[i*LCD_WIDTH + j];
- if(S2 == 0)
- m = ~m;
- LCD_Write_Data(m);
- }
- LCD_Write_Command(LC_AUT_OVR);
- }
- }
- else
- {
- k = 0;
- while(k!=128/8*LCD_HEIGHT)
- {
- LCD_Write_Command_P2(LC_GRH_STP,k%256,k/256);
- for(x=0;x<5000;x++);
- k+=LCD_WIDTH;
- }
- }
- }
- for(x=0;x<40000;x++);
- }
