Question

在使用Arduino IDE编程时，为V3 NodeMCU附加中断，我有点迷失。

所以我写了这个设置代码：

void setup() {
  //declare output and input pins
  pinMode(D4, OUTPUT);
  pinMode(D2, INPUT);
  attachInterrupt(digitalPinToInterrupt(D2), buttonPressed, CHANGE);
  pinMode(D7, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(D7), motionDetected, CHANGE);
  //start the serial monitor (test purposes only)
  Serial.begin(115200);
  //initiate the EEPROM access and check stored values
  EEPROM.begin(512);
  getSetupVariables();
  //setup the wifi connection to previous set SSID and password
  setup_wifi();
  //set the MQTT server to previous declared values and set the callback function
  client.setServer(mqtt_server, 1883);
  client.setCallback(handleMQTTCommands);
}

中断ISR是这两个功能：

void buttonPressed() {
  if(!isBusy && digitalRead(D2) == HIGH) {
    Serial.println("button pressed");
    if(targetDoorState == DOOR_STATE_OPEN) {
      initiateOperation(DOOR_STATE_CLOSED);
    } else if(targetDoorState == DOOR_STATE_CLOSED) {
      initiateOperation(DOOR_STATE_OPEN);
    }
  }
}

void motionDetected() {
  char MQTT_channel[100];
  char msg[100];
  detachInterrupt(D7);
  MQTT_CHANNEL_SET_VALUE.toCharArray(MQTT_channel, (MQTT_CHANNEL_SET_VALUE.length() + 1));
  if(digitalRead(D7) == HIGH) {
    Serial.println("reached");
    String MQTT_PAYLOAD_OBSTRUCTION_DETECTED   = "{\"name\":\"" + DEVICE_NAME + "\", \"service_name\":\"garagedoor\",\"characteristic\":\"ObstructionDetected\", \"value\":"+ DOOR_STATE_OPEN +"}";
  } else if(digitalRead(D7) == LOW) {
    String MQTT_PAYLOAD_OBSTRUCTION_DETECTED   = "{\"name\":\"" + DEVICE_NAME + "\", \"service_name\":\"garagedoor\",\"characteristic\":\"ObstructionDetected\", \"value\":"+ DOOR_STATE_CLOSED +"}";
  }
  MQTT_PAYLOAD_OBSTRUCTION_DETECTED.toCharArray(msg, (MQTT_PAYLOAD_OBSTRUCTION_DETECTED.length() + 1));
  client.publish(MQTT_channel, msg);
  delay(500);
  attachInterrupt(digitalPinToInterrupt(D7), motionDetected, CHANGE);
}

因此，在引脚D2上连接了一个按钮。 D7必须收听运动传感器的变化。但是当触发运动传感器（因此需要发生D7中断）时，D2和D7中断IRE都会被调用。有没有人有同样的问题？或者看到我在这里做错了什么？

我尝试过不同的NodeMCU板，所有这些都有这个问题。我还搜索了代码示例，但它们都实现了一个attachInterrupt。当我评论其中一个时，它们工作得很好......

提前致谢！
