用avr输出驱动l298n再驱动直流两个直流电机。可是编程总是出现错误，真的不太明白呀
#include <avr/io.h>
#include <avr/wdt.h>
//#include <util/delay.h>
#include <avr/interrupt.h>

#define Robot_Enable { PORTA |=(1<<PA5)}       //电机使能
#define Robor_Disable { PORTA &=～(1<<PA5)}    //电机禁止

#define D0 PORTA.0
#define D1 PORTA.1
#define D2 PORTA.2
#define D3 PORTA.3

void motor_ctl(void)                         //电机控制程序
{
  if (PORTC.0==1)                            //向前
  {
D0=1;
D1=0;
D2=1;
D3=0;
  }
  else if (PORTC.1==1)                         //向后
  {
D0=0;
D1=1;
D2=0;
D3=1;
  }
  else if (PORTC.2==1)                      //向左
  {
D0=0;
D1=1;
D2=1;
D3=0;
  }
  else if (PORTC.3==1)                      //向右
  {
D0=1;
D1=0;
D2=0;
D3=1;
  }

  void port_init(void)                      //端口初始化
  {
   DDRA=0xFF;
   PORTA=0xFF;
  }
  int main()
  {
port_init();
while(1)
{
   motor_ctl();
}
return 0;
  }
}
出现错误../a.c:16: error: expected ')' before numeric constant
