ESP32如何中断函数正确使用

Question

ESP32用中断函数按键控制发送MODBUS指令控制继电器不动作, 串口监视器能检测到按键动作，继电器不动，是中断函数不支持这样通信吗？

void setup() {
  
  Serial.begin(115200);
  Serial2.begin(9600);
  pinMode(34,INPUT_PULLDOWN);
  pinMode(35,INPUT_PULLDOWN);
  pinMode(18,INPUT_PULLUP);
  pinMode(19,INPUT_PULLUP);
  attachInterrupt(interruptPin1,ISR,FALLING);
  attachInterrupt(interruptPin1,DAOZHU,CHANGE);
  attachInterrupt(interruptPin2,DAOBEI,CHANGE);
}

void loop() {  
  Serial.print(digitalRead(interruptPin1));
  delay(1000);
  Serial.print(digitalRead(interruptPin2));
  delay(1000);
  /*Serial2.write(relay_ON5,sizeof(relay_ON5));
  delay(5000);
  Serial2.write(relay_OFF5,sizeof(relay_OFF5));
  delay(5000);*/
}

void ISR()
{
  Serial.print("断开");
}

void DAOZHU() 
{
  static unsigned long lasttime = 0;
  unsigned long intime = millis();
  if(intime - lasttime > 200){
    Serial2.write(relay_ON0,sizeof(relay_ON0));
    delay(5000);
    Serial2.write(relay_OFF0,sizeof(relay_OFF0));
  }
  lasttime = intime;
}

void DAOBEI() 
{
  static unsigned long lasttime = 0;
  unsigned long intime = millis();
  if(intime - lasttime > 200)
  {
    Serial2.write(relay_ON0,sizeof(relay_ON0));
    delay(5000);
    Serial2.write(relay_OFF0,sizeof(relay_OFF0));
  }
  lasttime = intime;
}
