液晶显示器(LCD)是一种常用的显示屏,在许多电子产品中经常使用它来以文本或图像格式显示信息。LCD用于在其屏幕上显示字母、数字等字符。LCD显示器由8条数据线和3条控制线组成,用于将LCD显示器与8051单片机连接。
考虑使用基于Proteus的模拟LCD与8051单片机的接口是:
如何在LCD显示屏上显示“8051单片机”,案例程序如下:
#include< reg51.h >#definekam P0voidlcd_initi();voidlcd_dat(unsignedchar);voidlcd_cmd(unsignedchar);voiddelay();voiddisplay(unsignedchar*s,unsignedcharr)sbit rs=P2^0; sbit rw=P2^1; sbit en=P2^2;voidmain(){lcd_initi();lcd_cmd(0x80);delay(100);lcd_cmd(0xc0);display("8051单片机",10);while(1); }voiddisplay(unsignedchar*s,unsignedcharr){ unsignedint w;for(w=0;w< r;w++) {lcd_data(s[w]); } }voidlcd_initi() {lcd_cmd(0x01);delay(100);lcd_cmd(0x38);delay(100);lcd_cmd(0x06);delay(100);lcd_cmd(0x0c);delay(100); }voidlcd_dat(unsignedchardat) { kam = dat; rs=1; rw=0; en=1;delay(100); en=0; } }voidlcd_cmd(unsignedcharcmd) { kam=cmd; rs=0; rw=0; en=1;delay(100); en=0; }voiddelay(unsignedintn){ unsignedint a;for(a=0;a< n;a++); }
