为什么显示错误
我的一个小程序只要显示千位数
应该显示 1的
为什么会显示 2 呢?
应如何解决?
#include<reg52.h>
#include<intrins.h>
sbit HC138_A = P1^0;
sbit HC138_B = P1^1;
sbit HC138_C = P1^2;
unsigned char code smgduan={0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0Xff};
void delay7ms(void) //误差 0us
{
unsigned char a,b,c;
for(c=1;c>0;c--)
for(b=26;b>0;b--)
for(a=133;a>0;a--);
}
void main()
{
unsigned int x = 32;
unsigned int y = 54;
unsigned int z;
z = x*y; //答案 1728
while(1)
{
P0 = 0X00;
HC138_A = 0; HC138_B = 0; HC138_C = 0; P0 = smgduan; delay7ms();
}
}
smgduan等于0x5b，显示2
