非常感谢您的问题。以下是我基于Arduino的代码,以实现您所需的功能:
```
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <ArduinoJson.h>
#include <Adafruit_SSD1306.h>
#include <Wire.h>
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* calendarAPI = "http://your_calendar_api_url"; // 替换为您的日历API URL
const int SCREEN_WIDTH = 128;
const int SCREEN_HEIGHT = 64;
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);
void setup() {
Serial.begin(115200);
delay(100);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // 0x3C是OLED显示器的I2C地址
display.clearDisplay();
display.display();
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("WiFi connected");
}
void loop() {
if (WiFi.status() == WL_CONNECTED) {
HTTPClient http;
http.begin(calendarAPI);
int httpCode = http.GET();
if (httpCode == 200) {
String payload = http.getString();
const size_t capacity = JSON_ARRAY_SIZE(3) + 3*JSON_OBJECT_SIZE(2) + JSON_OBJECT_SIZE(3) + 130;
DynamicJsonDocument doc(capacity);
deserializeJson(doc, payload);
JsonArray events = doc["events"];
display.clearDisplay();
display.setTextSize(1);
display.setTextColor(SSD1306_WHITE);
display.setCursor(0, 0);
display.println("Upcoming events:");
for (JsonVariant event : events) {
JsonObject eventObj = event.as<JsonObject>();
const char* name = eventObj["name"];
const char* time = eventObj["time"];
display.println(name);
display.println(time);
}
display.display();
}
http.end();
}
delay(60000); // 每隔60秒刷新一次日程
}
```
此代码将从您的API中获取JSON格式的日历数据,并在OLED显示屏上显示最近的三个事件。您需要将“your_SSID”和“your_PASSWORD”替换为您的WiFi凭据,并将“your_calendar_api_url”替换为您的日历API URL。请注意,您需要将API返回的数据格式化为JSON,并确保具有“events”属性的JSON数组,该数组包含您的日历事件的名称和时间。
