给我写一个用PS2遥控器通过arduino控制L298N的程序 chatGPT

//定义L298N引脚
int enA = 9;
int in1 = 8;
int in2 = 7;
//定义PS2遥控器引脚
int ps2_data = 2;
int ps2_cmd = 3;
int ps2_att = 4;
int ps2_clk = 5;
void setup() {
  //初始化L298N引脚
  pinMode(enA, OUTPUT);
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);
  
  //初始化PS2遥控器引脚
  pinMode(ps2_data, INPUT);
  pinMode(ps2_cmd, INPUT);
  pinMode(ps2_att, INPUT);
  pinMode(ps2_clk, INPUT);
}
void loop() {
  //读取PS2遥控器按键
  int ps2_key = readPS2();
  
  //根据按键控制L298N
  switch(ps2_key) {
    case 0: //按键0，停止
      digitalWrite(enA, LOW);
      break;
    case 1: //按键1，正转
      digitalWrite(enA, HIGH);
      digitalWrite(in1, HIGH);
      digitalWrite(in2, LOW);
      break;
    case 2: //按键2，反转
      digitalWrite(enA, HIGH);
      digitalWrite(in1, LOW);
      digitalWrite(in2, HIGH);
      break;
  }
}
//读取PS2遥控器按键
int readPS2() {
  int data = 0;
  digitalWrite(ps2_att, HIGH);
  digitalWrite(ps2_cmd, LOW);
  digitalWrite(ps2_clk, LOW);
  delayMicroseconds(10);
  digitalWrite(ps2_cmd, HIGH);
  delayMicroseconds(10);
  data = digitalRead(ps2_data);
  digitalWrite(ps2_clk, HIGH);
  delayMicroseconds(10);
  digitalWrite(ps2_cmd, LOW);
  delayMicroseconds(10);
  return data;
}
