/*

WiFi Web Server LED Blink

A simple web server that lets you blink an LED via the web.

This sketch will print the IP address of your WiFi Shield (once connected)

to the Serial monitor. From there, you can open that address in a web browser

to turn on and off the LED on pin 5.

If the IP address of your shield is yourAddress:

http://yourAddress/H turns the LED on

http://yourAddress/L turns it off

This example is written for a network using WPA encryption. For

WEP or WPA, change the Wifi.begin() call accordingly.

Circuit:

* WiFi shield attached

* LED attached to pin 5

#include <WiFi.h>

const char* ssid = «yourssid»;

const char* password = «yourpasswd»;

WiFiServer server(80);

void setup()

{

Serial.begin(115200);

pinMode(5, OUTPUT); // set the LED pin mode

delay(10);

// We start by connecting to a 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());

server.begin();

}

int value = 0;

void loop(){

WiFiClient client = server.available(); // listen for incoming clients

if (client) { // if you get a client,

Serial.println(«New Client.»); // print a message out the serial port

String currentLine = «»; // make a String to hold incoming data from the client

while (client.connected()) { // loop while the client’s connected

if (client.available()) { // if there’s bytes to read from the client,

char c = client.read(); // read a byte, then

Serial.write(c); // print it out the serial monitor

if (c == ‘n’) { // if the byte is a newline character

// if the current line is blank, you got two newline characters in a row.

// that’s the end of the client HTTP request, so send a response:

if (currentLine.length() == 0) {

// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)

// and a content-type so the client knows what’s coming, then a blank line:

client.println(«HTTP/1.1 200 OK»);

client.println(«Content-type:text/html»);

client.println();

// the content of the HTTP response follows the header:

client.print(«Click <a href=»/H»>here</a> to turn the LED on pin 5 on.<br>»);

client.print(«Click <a href=»/L»>here</a> to turn the LED on pin 5 off.<br>»);

// The HTTP response ends with another blank line:

client.println();

// break out of the while loop:

break;

} else { // if you got a newline, then clear currentLine:

currentLine = «»;

}

} else if (c != ‘r’) { // if you got anything else but a carriage return character,

currentLine += c; // add it to the end of the currentLine

}

// Check to see if the client request was «GET /H» or «GET /L»:

if (currentLine.endsWith(«GET /H»)) {

digitalWrite(5, HIGH); // GET /H turns the LED on

}

if (currentLine.endsWith(«GET /L»)) {

digitalWrite(5, LOW); // GET /L turns the LED off

}

}

}

// close the connection:

client.stop();

Serial.println(«Client Disconnected.»);

}

}

SO i have been getting this error window when i compile a simple code to run different LED lights on the ESP32-S2-SOLA (Wrovere) module

Code:

int LED_BUILTIN = 2;
    
void setup() {
    pinMode (LED_BUILTIN, OUTPUT);
}
    
void loop() {
    digitalWrite(LED_BUILTIN, HIGH);
    delay(1000);
    digitalWrite(LED_BUILTIN, LOW);
    delay(1000);
}

Эта ошибка связана с отсутствием объявления функции std::round(), которая используется в вашем коде. Она вызвана тем, что компилятор не может найти объявление этой функции из-за неправильной настройки для библиотек.

Вы можете исправить эту проблему, добавив следующую строку в начало вашего скетча:

#include <cmath>

Эта директива загрузит библиотеку cmath, которая содержит объявление std::round(), и позволит вашему коду успешно скомпилироваться.

Если вы все еще сталкиваетесь с проблемой, убедитесь, что ваша версия Arduino IDE и библиотеки ESP32 обновлены до последней версии, и повторите попытку.

Удачи!
