Question

uchar code DSY_CODE 什么意思

Answer 1

你这个应该是单片机的C代码吧
uchar是unsigned char的缩写, code说明代码存放的位置是在rom里面, DSY_CODE是变量名

Answer 2

#include <reg52.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
uchar Count;
sbit Dot = P0^7;
uchar code DSY_CODE[]=
{
0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f
};

uchar Digits_of_6DSY[]=;

void DelayMS(uint x)
{
uchar i;
while(--x)
{
for(i=0;i<120;i++);
}
}

void main()
{
uchar i,j;
P0 = 0x00;
P3 = 0xff;
Count =0;
TMOD = 0x01;
TH0 = (65535-50000)/256;
TL0 = (65535-50000)%256;
IE = 0x82;
TR0 = 1;
while(1)
{
j = 0x7f;
for(i=5;i!=-1;i--)
{
j=_crol_(j,1);
P3 = j;
P0 = DSY_CODE[Digits_of_6DSY[i]];
if(i==1) P0 |= 0x80;
DelayMS(2);
}
}
}

void Time0() interrupt 1
{
uchar i;
TH0 = (65535-50000)/256;
TL0 = (65535-50000)%256;
if(++Count !=2) return;
Count = 0;
Digits_of_6DSY[0]++;
for(i=0;i<=5;i++)
{
if(Digits_of_6DSY[i] == 10)
{
Digits_of_6DSY[i] = 0;
if(i != 5) Digits_of_6DSY[i+1]++;
}
else break;
}
}
