LCD Programming using 8051 Microcontroller

Liquid Crystal Display (LCD) is an electronic device, which is frequently used in many applications for displaying the information in a text or image format. The LCD is used for displaying the alphanumeric character on its screen. The LCD display is consists of 8-data lines and 3-control lines which are used for interfacing the LCD display with 8051 microcontroller.

Consider the interfacing of LCD with 8051 Microcontroller using Proteus based simulation is:-

Consider the program to display the “tutoraspire” on LCD display is:-

 #include #define kam P0 void lcd_initi(); void lcd_dat(unsigned char ); void lcd_cmd(unsigned char ); void delay(); void display(unsigned char *s, unsigned char r) sbit rs=P2^0; sbit rw=P2^1; sbit en=P2^2; void main() { lcd_initi(); lcd_cmd(0x80); delay(100); lcd_cmd(0xc0); display(“tutoraspire”,10); while(1); } void display(unsigned char *s, unsigned char r) { unsignedint w; for(w=0;w;w++)>
