液晶是非常容易見到的,大街小巷亮著液晶顯示屏隨處可見,而且其原理與發(fā)光二極管一致,所以不用過多介紹,只是要注意它的說明書和與之對應(yīng)的電路圖,設(shè)置一些引腳,僅此而已??匆粋€程序,這是最簡單驅(qū)動液晶的:

#define uchar unsigned char
#define uint unsigned int
uchar code table[]="I LIKE MCU!";
uchar code table1[]="WWW.TXMCU.COM";
sbit lcden=P3^4;
sbit lcdrs=P3^5;
sbit dula=P2^6;
sbit wela=P2^7;
uchar num;
void delay(uint z)
{
uint x,y;
for(x=z;x>0;x--)
for(y=110;y>0;y--);
}
void write_com(uchar com)
{
lcdrs=0;
P0=com;
delay(5);
lcden=1;
delay(5);
lcden=0;
}
void write_data(uchar date)
{
lcdrs=1;
P0=date;
delay(5);
lcden=1;
delay(5);
lcden=0;
}
void init()
{
dula=0;
wela=0;
lcden=0;
write_com(0x38);
write_com(0x0e);
write_com(0x06);
write_com(0x01);
write_com(0x80+0x10);
}
void main()
{
init();
for(num=0;num<11;num++)
{
write_data(table[num]);
delay(20);
}
//write_com(1);
write_com(0x80+0x53);
for(num=0;num<13;num++)
{
write_data(table1[num]);
delay(20);
}
for(num=0;num<16;num++)
{
write_com(0x18);
delay(20);
}
while(1);
}
理順一下就可以了,不難理解。
