老规矩，上程序：
先来一个不用SPI方式控制LCD显示的实例：
#include ""
#include <>
void delay(uint n){
//26 cycles delay
while(--n)asm("NOP");
}
void LCD_IOInit(){
P0SEL &=~ 0X03;
P0DIR |= 0X03;
P1SEL &=~ 0XF0;
P1DIR |= 0XF0;
}
void LCD_WriteOneByte(uchar data){
uchar i = 0;
for(i=0;i<8;i++){
LCD_SCK = 0;
if((data<<i)&0x80){
LCD_SIN = 1;
}
else{LCD_SIN = 0;}
LCD_SCK = 1;
}
}
void LCD_WriteMByte(uchar *data,uint num){
while(num--){
LCD_WriteOneByte(*data);
data++;
}
}
void LCD_Init(){
LCD_nCS = 0;
delay(100);
LCD_nRES = 0;
delay(100);
LCD_nRES = 1;
delay(100);
LCD_DnC = 0;
LCD_WriteOneByte(0x21);
LCD_WriteOneByte(0xC8);
LCD_WriteOneByte(0x06);
LCD_WriteOneByte(0x13);
LCD_WriteOneByte(0x20);
LCD_WriteOneByte(0x0C);
LCD_DnC = 1;
}
main(){
uint i = 0;
uchar Hello[]={
0x00,0x7E,0x10,0x10,0x7E,0x00,/*"H",0*/
/* (6 X 8 , 楷体_GB2312 )*/
0x00,0x7E,0x52,0x52,0x42,0x00,/*"E",1*/
/* (6 X 8 , 楷体_GB2312 )*/
0x42,0x7E,0x42,0x40,0x40,0x00,/*"L",2*/
/* (6 X 8 , 楷体_GB2312 )*/
0x42,0x7E,0x42,0x40,0x40,0x00,/*"L",3*/
/* (6 X 8 , 楷体_GB2312 )*/
0x00,0x3C,0x42,0x42,0x3C,0x00,/*"O",4*/
/* (6 X 8 , 楷体_GB2312 )*/};
LCD_IOInit();
LCD_Init();
//for(i=0;i<30;i++){
//LCD_WriteOneByte(Hello[i]);
//}
LCD_WriteMByte(Hello,30);
LCD_nCS = 1;
}
下面是采用SPI总线方式控制LCD显示的例子：
//========================

#include <>
void delay(uint n){
//26 cycles delay
while(--n)asm("NOP");
}
void LEDInit(){
P1SEL &= 0XFE; //P1_0 defined General purpose I/O
P1DIR |= 0X01; //P1_0 defined Output
DEBUG_LED = 1; //LED light up
}
//========================
//Initial P1-USART1-SPI
