关于使用心知服务天气预报的说明
非常感谢您的提问!关于您的问题,以下是我给出的代码:
```
#include <WiFi.h>
#include <TFT_eSPI.h>
#include <lvgl.h>
#include <HeartBeat.h>
#include <HeartRate.h>
const char* ssid = "您的WiFi名称";
const char* password = "您的WiFi密码";
TFT_eSPI tft = TFT_eSPI();
HeartBeat heartBeat(25);
HeartRate heartRate(A8);
void setup()
{
tft.init();
tft.setRotation(0);
tft.fillScreen(TFT_BLACK);
lv_init();
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
delay(1000);
}
}
void loop()
{
lv_task_handler();
heartRate.update();
int heartRateValue = heartRate.getRate();
tft.setCursor(0, 0);
tft.setTextColor(TFT_GREEN);
tft.setTextSize(3);
tft.printf("心率:%d", heartRateValue);
char* weatherJson = getWeather("您的城市", "您的API Key");
char* weatherTemp = parseTemp(weatherJson);
char* weatherHumidity = parseHumidity(weatherJson);
tft.setCursor(0, 50);
tft.setTextColor(TFT_WHITE);
tft.setTextSize(2);
tft.printf("温度:%s", weatherTemp);
tft.setCursor(0, 80);
tft.setTextColor(TFT_WHITE);
tft.setTextSize(2);
tft.printf("湿度:%s", weatherHumidity);
delay(1000);
}
char* getWeather(const char* city, const char* apiKey)
{
const char* host = "api.seniverse.com";
const int httpPort = 80;
WiFiClient client;
if (!client.connect(host, httpPort))
{
return "";
}
String url = "/v3/weather/now.json?key=" + String(apiKey) + "&location=" + String(city);
client.print(String("GET ") + url + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
while (!client.available())
{
delay(1000);
}
String response = "";
while (client.available())
{
String line = client.readStringUntil('\r');
response += line;
}
client.stop();
return response.c_str();
}
char* parseTemp(char* json)
{
char* tempStart = strstr(json, "temperature\":\"");
if (tempStart == NULL)
{
return "";
}
tempStart += strlen("temperature\":\"");
char* tempEnd = strstr(tempStart, "\"");
if (tempEnd == NULL)
{
return "";
}
*tempEnd = '\0';
return tempStart;
}
char* parseHumidity(char* json)
{
char* humidityStart = strstr(json, "humidity\":\"");
if (humidityStart == NULL)
{
return "";
}
humidityStart += strlen("humidity\":\"");
char* humidityEnd = strstr(humidityStart, "\"");
if (humidityEnd == NULL)
{
return "";
}
*humidityEnd = '\0';
return humidityStart;
}
```
在这个代码中,我使用了HeartBeat和HeartRate库来检测人的心率,使用了lvgl库来创建用户界面,并使用了TFT_eSPI库来控制TFT显示器。为了获取天气数据,我使用了心知天气API来查找指定城市的实时天气信息。由于您没有提供API Key,您需要替换掉代码中的“您的API Key”和“您的城市”部分。
这是我的回答,希望我的代码可以帮助您实现所需功能,谢谢!
