沒錢買片子只能用虛擬了。建議大家不要學pic，pic沒學頭，要搞就搞arm 

#include<pic.h>
#include<stdio.h>
#define uint unsigned int
#define uchar unsigned char
uchar H_time=0,L_time=0;
const uchar tab[]={0x0a,0x22,0x11,0x14};
extern uchar code[]={0x00,0x00,0x00,0x00};
void delay(uint z)
{
uint x,y;
for(x=z;x>0;x--)
for(y=5;y>0;y--);
}
void light(uchar n)
{
uchar i,top,temp;
for(;n>0;n--)
{
PORTC=H_time*16+L_time;
H_time++;L_time++;
temp=0x00;
for(i=0;i<0xff;i++)
{
temp++;
PORTD=temp;
delay(2);
}
}
}
void RGB_light()
{
PORTB=tab[0];
light(7);H_time=0x00;
PORTB=tab[1];
light(2);H_time=0x00;L_time=0x00;

light(2);H_time=0x00;L_time=0x00;
PORTB=0X00;

}
void main()
{
TRISD=0;
TRISB=0;
TRISC=0;
while(1)
{
RGB_light();
}

}
