Question

出现错误：led.c(12): error C141: syntax error near 'void', expected '__asm'
led.c(14): error C141: syntax error near 'void', expected '__asm'

#include <REGX52.H>

//void delay(unsigned int n);
void Delay500ms();

void main(void)
{
while(1)
{
P2 = 0xfe;
void Delay500ms();
P2 = 0xff;
void Delay500ms();

}

}

void Delay500ms() //@11.0592MHz
{
unsigned char i, j, k;

_nop_();
i = 4;
j = 129;
k = 119;
do
{
    do
    {
        while (--k);
    } while (--j);
} while (--i);

}

Answer 1

led.c
12行和14行
void Delay500ms();
改成
Delay500ms();
去掉 void
