Question

为什么C语言编程在Keil uVision2中一直有编辑错误，说我没定义data scan_con[6]和code LEDValue[]里面的数

#include<reg52.h>
#define uchar unsigned char
#define led_data P0
#define led_bit P2
uchar code LEDValue[]={Ox3f,Ox06,Ox5b,Ox4f,Ox66,Ox6d,Ox7d,Ox07,Ox7f,Ox6f,Ox00};
uchar data scan_con[6]={Ox01,Ox02,Ox04,Ox08,Ox10,Ox20};
delay1ms(int t)
{
int i,j;
for(i=0;i<t;i++)
for(j=0;j<120;j++)
;}
display()
{
uchar k;
for(k=0;k<6;k++)
{
led_data=code LEDValue[k];
led_bit=data scan_con[k];
delay1ms(1);
led_bit=Ox00;
}
}
main()
{
while(1)
{
display();
}
}

Answer 1

uchar code LEDValue[]={Ox3f,Ox06,Ox5b,Ox4f,Ox66,Ox6d,Ox7d,Ox07,Ox7f,Ox6f,Ox00};
uchar data scan_con[6]={Ox01,Ox02,Ox04,Ox08,Ox10,Ox20};

把OX3f.......改成0x3f
X前那个是0(零),不是O(欧).

Answer 2

#include<reg52.h>
#define uchar unsigned char
#define led_data P0
#define led_bit P2
uchar code LEDValue[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x00};
uchar data scan_con[6]={0x01,0x02,0x04,0x08,0x10,0x20};
delay1ms(int t)
{
int i,j;
for(i=0;i<t;i++)
for(j=0;j<120;j++)
;}
display()
{
uchar k;
for(k=0;k<6;k++)
{
led_data=LEDValue[k];
led_bit=scan_con[k];
delay1ms(1);
led_bit=0x00;
}
}
main()
{
while(1)
{
display();
}
}
这样就没语法错误，功能不清楚要求没改

Answer 3

没看懂

Answer 4

不是很懂
