Question

小车在下面 芯片AT89S52
这是我自己写的 求把加速减速停止写进去
#include
#include
#define LeftIR P1_2 //左边红外接收连接到P12
#define RightIR P1_3 //右边红外接收连接到P13
void Forward(int Velocity)
/* Velocity should be between 0 and 200 */
{

    P1_1=1;
    delay_nus(1500+ Velocity);
    P1_1=0;
    P1_0=1;
    delay_nus(1500- Velocity);
    P1_0=0;
    delay_nms(80);

}
void Left()
/* Velocity should be between 0 and 200 */
{

    P1_1=1;
    delay_nms(20);  
    P1_1=0;
    P1_0=0;
    P1_0=0;

   delay_nus(1300);

}
void Right()
/* Velocity should be between 0 and 200 */
{

    P1_1=0;
    P1_1=0;
    P1_0=1;

}
}
int main(void)
{

while(1)
{

uart_Init();
printf("Program Running!\n");


if&&(RightIR==0)&&(LeftIR==0))  
 {Forward(600);}                                                       //前进



if((RightIR==1)||(RightIR==))                                                //左weitiao
{
Left();
}


if((LeftIR==1)||(LeftIR==1))                                                      //右weitiao
{
Right();
}

}

}
