C語言 編譯 ERROR: PREPROCESSOR: MACROS TOO NESTED
你前面7個宏定義怎麼回事？用同一個數組名來表示7個不同大小的數組空間？我沒有見過這種用法
單片機中出現這樣的錯誤們指條明路 MACROS TOO NESTED C51 TERMINATEDTarget not created
#include<reg52.h>
#include<intrins.h>
#define uint unsigned int
#define uchar unsigned char
uchar temp;
void delay(uint);
void main()
{
temp=0xfe;
P1=temp;
while(1)
{
temp=_crol_(temp,1);
delay(600);
P1=temp;
}
}
void delay(uint ms)
{
uint i;
for(i=0;i<ms;i++)
{
}
}
