1 源程序！！ #include #include typedef unsigned int uint; typedef unsigned char uchar; void Delay(uint m,uint n) { uint i,j; for(i=0;i for(j=0;j ; } void GPIO_Init(void) { DDRA=0xFF; DDRD=0xFF; DDRB=0xFF; PORTA&=~BIT(3);//RS PORTA&=~BIT(4);//RW PORTA&=~BIT(5);//EN } void Read_Busy(void) { uchar dat=0; DDRD=0x00; PORTA&=~(1<<3); PORTA\|=(1<<4); PORTA\|=(1<<5);//直接上高电平无需上升沿 Delay(10,10);//加一个小小的延时 dat=PIND; Delay(10,10); PORTA&=~(1<<5); DDRD=0xFF; while(dat&0x80); } void Write_Dat(uchar dat)//写数据 { Read_Busy(); PORTA\|=(1<<3);//RS PORTA&=~(1<<4);//RW PORTA&=~(1<<5);//EN Delay(10,10); PORTD=dat; Delay(10,10); PORTA\|=(1<<5); Delay(10,10); PORTA&=~(1<<5); } void Write_Command(uchar com)//写命令 { Read_Busy(); PORTA&=~(1<<3); PORTA&=~(1<<4); PORTA&=~(1<<5); Delay(10,10); PORTD=com; Delay(10,10); PORTA\|=(1<<5); Delay(10,10); PORTA&=~(1<<5); } void LCD_Init(void)//初始化 { Write_Command(0x38); Delay(200,20); Write_Command(0x06); Delay(200,20); Write_Command(0x0C); Delay(200,20); Write_Command(0x01); Delay(200,20); } void main(void) { GPIO_Init(); LCD_Init(); while(1) { Write_Command(0x80+0x40); Write_Dat(' ');//显示空格 Delay(200,200); Write_Command(0x80+0x40); Write_Dat('T'); Delay(200,200); } } 时序都一样！ 1
