Esp8266和ht66f2390代码

对于ESP8266，这里提供一个简单的示例代码，可以通过Wi-Fi连接到Internet，并向指定的URL发送HTTP请求：

#include <ESP8266WiFi.h>
#include <WiFiClient.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

void setup() {
  Serial.begin(9600);
  delay(10);

  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");  
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  WiFiClient client;

  const int httpPort = 80;
  if (!client.connect("www.example.com", httpPort)) {
    Serial.println("connection failed");
    return;
  }

  // We now create a URI for the request
  String url = "/api/v1/data";

  Serial.print("Requesting URL: ");
  Serial.println(url);

  // This will send the request to the server
  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: www.example.com\r\n" +
               "Connection: close\r\n\r\n");
  delay(500);

  // Read all the lines of the response from server and print them to Serial
  while(client.available()){
    String line = client.readStringUntil('\r');
    Serial.print(line);
  }

  Serial.println();
  Serial.println("closing connection");
}

对于HT66F2390，这里提供一个简单的示例代码，可以使用定时器中断来控制LED灯的闪烁：

#include "ht66f2390.h"

// Define LED pin
sbit LED = P3^5;

void Timer0_ISR() interrupt 1
{
  static unsigned char led_state = 0;
  
  // Toggle LED state
  led_state = !led_state;
  LED = led_state;
}

void main()
{
  // Initialize timer0
  TMOD = 0x01;   // Set timer0 as 16-bit timer
  TH0 = 0xFC;    // Set timer0 initial value
  TL0 = 0x67;
  TR0 = 1;       // Enable timer0
  ET0 = 1;       // Enable timer0 interrupt
  
  // Enable interrupts
  EA = 1;
  
  while(1)
  {
    // Main loop
  }
}

这是一个简单的例子，使用定时器中断控制LED灯的闪烁。在Timer0_ISR()函数中，每次中断时，改变LED灯的状态，并在主循环中等待。请注意，这只是一个简单的示例代码，可能需要根据您的具体应用进行修改。
