1602 LCD display C language programming-EEWORLD

Collect

First of all, I would like to state that this program was not written by me. It is a program in Guo Tianxiang's 51 video tutorial. I used it when I started learning about microcontrollers. It is completely feasible.

#include
#define uchar unsigned char
#define uint unsigned int
sbit lcden=P3^7;
sbit led=P3^6;
sbit lcdrs=P3^5;
uchar num;
uchar code table[]="I LIKE MCU!";

void delay(uint i)
{
uchar j;
for(;i>0;i--)
for(j=110;j>0;j--);
}

void write_1602com(uchar com)
{
lcdrs=0;
P0=com; //数据口
delay(5);
lcden=1;
delay(5);
lcden=0;
}

void write_1602(uchar date)
{
lcdrs=1;
P0=date; //数据口
delay(5);
lcden=1;
delay(5);
lcden=0;
}

void init_1602()
{
lcden=0;
write_1602com(0x38);
write_1602com(0x0e);
write_1602com(0x06);
write_1602com(0x01);
write_1602com(0x80+0x10);
}

void main()
{
init_1602();
for(num=0;num<11;num++)
{
write_1602(table[num]);
delay(20);
}
while(1);
}

Some experience about 1602 LCD

I started reviewing LCD today! Oh my god! It feels like I'm learning it all over again. I've forgotten a lot of things. It seems that I need to practice very hard to be proficient in it. You won't remember what you learn in a short time with temporary efforts! Not to mention being proficient in application! Let me t
