請(qǐng)教各位大神,我程序錯(cuò)在哪里?
#include <reg51.h>
#define uchar unsigned char
#define uint unsigned int
#define p1
#define LED
sbit LED = p1^0;
void DelayMS(uint x )
{ uchar i;
while (x--)
{for(i=120;i>0;i--);}
}
void main()
{ LED = 0;
while(1)
{
LED=~LED;
DelayMS(150);
}
}錯(cuò)誤提示為
一位閃燈.C(1): warning C500: MISSING LICENSE ID CODE (LIC) IN 'TOOLS.INI'
一位閃燈.C(6): error C141: syntax error near '<', expected '<id>'
一位閃燈.C(10): error C129: missing ';' before '>'是什么意思?

#define p1
#define LED
這兩句好像有問(wèn)題,宏定義不完整,還有while(x--)貌似也用錯(cuò)了,我也是這兩天才學(xué)單片機(jī),有說(shuō)得不對(duì)的大家也指點(diǎn)我一下
