在"｛"标记之前应为不合格的id

Question

我可能只是瞎了眼，但我似乎没有发现这段代码有任何问题。我在L298N h桥上运行两台直流电机，只是想改变它们的方向。

我一直收到这个错误：sketch_mar23a。ino:61:1:error:在"｛"标记之前应该是不合格的id

这是代码：

//Motor A
int enA = 9;
int in1 = 8;
int in2 = 7;
//Motor B
int enB = 3;
int in3 = 5;
int in4 = 4;
void setup()
{
pinMode(enA, OUTPUT);
pinMode(enB, OUTPUT);
pinMode(in1, OUTPUT);
pinMode(in2, OUTPUT);
pinMode(in3, OUTPUT);
pinMode(in4, OUTPUT); 
}
void demoOne()
{
//runs bopth motors
//motor A
digitalWrite(in1, HIGH);
digitalWrite(in2, LOW);
//set speed
analogWrite(enA, 200);
//motor B
digitalWrite(in3, HIGH);
digitalWrite(in4, LOW);
//set speed
analogWrite(enB, 200);
delay(2000);
//change direction
digitalWrite(in1, LOW);
digitalWrite(in2, HIGH);
digitalWrite(in3, LOW);
digitalWrite(in4, HIGH);
delay(2000);
//turn motors off
digitalWrite(in1, LOW);
digitalWrite(in1, LOW);
digitalWrite(in1, LOW);
digitalWrite(in1, LOW);
}

void loop();
{
demoOne();
delay(1000);
}

Answer 1

void loop();应为void loop()。卸下;。
