esp8266天气时钟0.96寸oled代码

以下是基于esp8266和0.96寸OLED显示屏的天气时钟代码，采用了BME280传感器获取温度、湿度和气压数据，并通过WiFi连接获取天气信息并实时更新显示：

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <SSD1306Wire.h>
#include <OLEDDisplayUi.h>

// WiFi设置
const char* ssid = "YourSSID";  // 你的WiFi名称
const char* password = "YourPassword";  // 你的WiFi密码

// 服务器设置
const String serverName = "http://api.openweathermap.org/data/2.5/weather?q=Shenzhen&appid=YourAPIKey";  // 你的OpenWeatherMap API Key和城市名称

// OLED显示屏设置
SSD1306Wire display(0x3c, D2, D1);
OLEDDisplayUi ui(&display);

// BME280传感器设置
Adafruit_BME280 bme;

// 时间设置
unsigned long currentTime = millis();
unsigned long previousTime = 0;
const long interval = 60000;  // 更新时间间隔，单位为毫秒

void setup() {
  Serial.begin(115200);

  // 初始化OLED显示屏
  display.init();
  display.setContrast(255);
  display.setFont(ArialMT_Plain_10);

  // 初始化BME280传感器
  if (!bme.begin(0x76)) {
    Serial.println("Could not find a valid BME280 sensor, check wiring!");
    while (1);
  }

  // 连接WiFi
  WiFi.begin(ssid, password);
  Serial.print("Connecting to ");
  Serial.println(ssid);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
}

void loop() {
  currentTime = millis();
  if (currentTime - previousTime >= interval) {
    // 获取天气信息
    if (WiFi.status() == WL_CONNECTED) {
      HTTPClient http;
      http.begin(serverName);
      int httpResponseCode = http.GET();
      if (httpResponseCode > 0) {
        String payload = http.getString();
        Serial.println(payload);

        // 解析JSON数据
        const size_t capacity = JSON_OBJECT_SIZE(3) + JSON_OBJECT_SIZE(4) + 60;
        DynamicJsonDocument doc(capacity);
        deserializeJson(doc, payload);
        const char* description = doc["weather"][0]["description"];
        float temp = doc["main"]["temp"];
        float humidity = doc["main"]["humidity"];
        float pressure = doc["main"]["pressure"];

        // 显示天气信息
        display.clear();
        display.drawString(0, 0, "Weather in Shenzhen");
        display.drawString(0, 12, description);
        display.drawString(0, 24, "Temp: " + String(temp) + " C");
        display.drawString(0, 36, "Humidity: " + String(humidity) + " %");
        display.drawString(0, 48, "Pressure: " + String(pressure) + " hPa");
        display.display();
      } else {
        Serial.println("Error on HTTP request");
      }
      http.end();
    } else {
      Serial.println("WiFi Disconnected");
    }

    previousTime = currentTime;
  }
}

需要注意的是，需要在OpenWeatherMap网站上注册账号并申请API Key，替换代码中的YourAPIKey和城市名称。

此外，如果你的OLED显示屏型号不同，可能需要修改相关的设置。
