你的P1_5、P1_7没有定义 sbit P1_5=P1^5; sbit P1_7=P1^7;

[yishumei]

下面的宏定义错误 #define Right_moto_pwm P1_7 //PWM信号端 #define Right_moto_go {P1_5=1,P1_6=0;} //右边电机向前走 #define Right_moto_back {P1_5=0,P1_6=1;} //右边电机向后走 #define Right_moto_Stop {P1_5=0,P1_6=0;} //右边电机停转

[dceacho]

楼上说的对，这里要用 ; 而非 ,

#define Right_moto_go     {P1_5=1; P1_6=0;}
