使用Arduino IDE将Arduino Node-MCU与Google Firebase连接

Question

这是我的代码：

#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>



// Set these to run example.
#define FIREBASE_HOST "EXAMPLE-12345.firebaseio.com"
#define FIREBASE_AUTH "secret"
#define WIFI_SSID "SSID"
#define WIFI_PASSWORD "PWD"

void setup() {
  Serial.begin(9600);

  // connect to wifi.
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("connecting");
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("connected: ");
  Serial.println(WiFi.localIP());

  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}

int n = 0;

void loop() {
  // set value
  Firebase.setFloat("number", 42.0);
  // handle error
  if (Firebase.failed()) {
    Serial.print("setting /number failed:");
    Serial.println(Firebase.error());
    return;
  }
  delay(1000);

  // update value
  Firebase.setFloat("number", 43.0);
  // handle error
  if (Firebase.failed()) {
    Serial.print("setting /number failed:");
    Serial.println(Firebase.error());
    return;
  }
  delay(1000);

  // get value
  Serial.print("number: ");
  Serial.println(Firebase.getFloat("number"));
  delay(1000);

  // remove value
  Firebase.remove("number");
  delay(1000);

  // set string value
  Firebase.setString("message", "hello world");
  // handle error
  if (Firebase.failed()) {
    Serial.print("setting /message failed:");
    Serial.println(Firebase.error());
    return;
  }
  delay(1000);

  // set bool value
  Firebase.setBool("truth", false);
  // handle error
  if (Firebase.failed()) {
    Serial.print("setting /truth failed:");
    Serial.println(Firebase.error());
    return;
  }
  delay(1000);

  // append a new value to /logs
  String name = Firebase.pushInt("logs", n++);
  // handle error
  if (Firebase.failed()) {
    Serial.print("pushing /logs failed:");
    Serial.println(Firebase.error());
    return;
  }
  Serial.print("pushed: /logs/");
  Serial.println(name);
  delay(1000);
}

这是我的错误：

** Arduino：1.8.5（Windows 10），主板：“NodeMCU 1.0（ESP-12E模块），80 MHz，115200,4M（3M SPIFFS）”

退出状态1编译板块NodeMCU 1.0（ESP-12E模块）时出错。**

请帮我！谢谢！

我有同样的问题。你必须降级你的ArduinoJson。

为了这; 1）草图 - >包含库 - >管理库2）在此窗口中，将“json”写入搜索框。你应该看到“Benoit Blanchon的ArduinoJson”。将其版本降级至5.13.2 3）关闭Arduino，再次打开。 4）将代码发送到您的NodeMCU 5）享受。
