各位高手老师在下想问下一个点亮1602液晶,按照郭老师51上课时讲的代码怎么点不亮1602液晶?
源代码如下: #include<reg52.h>
#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);
} 我用的单片机为STC89C52ZRC,YB1602A的液晶屏。1602液晶直接插在插座上对比度也调好了,但显示的就是一列方格。是不是一定要个HD44780的1602液晶才会显示?
