Single chip microcomputer learning - LCD1602 display experiment one

　　　"I LIKE MCU!

　　　　　　　XIAO WO ”

　　　And the display method is to dynamically move from the right screen to the left in sequence.

Solution: (C language programming)

#include
#define uchar unsigned char
#define uint unsigned int
uchar code table[]="I LIKE MCU!";
uchar code table1[]="XIAO WU"  ;
sbit lcdrs=P1^7;
sbit lcdrw =P1^6;
sbit lcde=P2^4;
sbit le=P3^  6;
sbit leden=P2^5;
sbit  dkle=P3^7;
void delay(uint a) ;
uchar num;

void write_com(uchar com) //write command sub-function
{
 lcde=0;
 lcdrw=0;
 lcdrs=0;
 delay(1);
 lcde=1;
 delay(1);
 P0=com;
 delay(1);
 lcde=0;
}
void write_data(uchar dat) //write data sub-function
{
 lcde=0;
 lcdrw=0;
 lcdrs=1;
 delay(1);
 lcde=1;
 delay(1);
 P0=dat;
 delay(1);
 lcde=0;
}
void init() //initialization sub-function
{
 lcde=0;
 le=0;
 leden=0;
 write_com(0x38);
 write_com(0x0f);
 write_com(0x01);
 write_com(0x80+0x10);
  
}
void main() //main function
{
 init();
 for(num=0;num<11;num++) //write the first line
 {
  write_data(table[num]);
  delay(1);
 }
 write_com(0x80+0x40+4+0x10);
 for(num=0;num<7;num++)//write the second line
 {
  write_data(table1[num]);
  delay(1);
 }
 for(num=0;num<16;num++) //dynamic left shift
 {
  write_com(0x18);
  delay(10);
 }
 while(1);
}

void delay(uint a) { //Delay function
 uint i,j;
 for(j=a;j>0;j--)
    for(i=2500;i>0;i--);
}
