啥情況 我對著師傅的一摸一樣 就是錯 把數組去掉就沒問題了
#include<reg52.h>
typedef unsigned char u8;
typedef unsigned int u16;
sbit seg_sel=P1^5;
sbit bit_sel=P1^4;
#define DATA P0
u8 seg_tab[]={0xc0,0xf9,0xa4,0xb0,
0x99,0x92,0x82,0xf8,
0x80,0x90}
void main(void){
P0=0Xff;
P1=0xff;
seg_sel=0;
bit_sel=0;
while(1){
bit_sel=1;
DATA=0x80;
bit_sel=0;
seg_sel=1;
DATA=seg_tab[1];
seg_sel=0;
}
}
錯誤
