У меня проблема с программным обеспечением, я контролирую реле через сетевой экран и arduino. Я получил код из сети, который отлично работает, и я могу отлично управлять реле. Но проблема, которую я получаю, - это когда я добавляю слишком много кнопок на HTML-страницу, HTML-страница просто не загружается. Только когда я использую max четыре кнопки, он работает, но когда я добавляю больше четырех, это не работает. Я представил код ниже, пожалуйста, если кто-нибудь может помочь мне добавить больше кнопок, не используя слишком много памяти, я бы решил свою проблему.Управление ретрансляторами через веб-сервер с экраном arduino и ethernet, но не может добавить более четырех кнопок, HTML-страница не загружается
Вот код:
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,177);
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
String readString = String(100); //string for fetching data from address
void setup()
{
Serial.begin(9600);
pinMode(6, OUTPUT);
pinMode(5, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
// start the Ethernet connection and the server:
Serial.println(F("Initiaizing ethernet..."));
// this uses a fixed address
Ethernet.begin(mac, ip);
// get an address with DHCP
//if (Ethernet.begin(mac) == 0)
// Serial.println("Failed to configure Ethernet using DHCP");
// give the card a second to initialize
delay(1000);
server.begin();
Serial.print(F("Garage Door Opener Control Ready at IP address "));
Serial.println(Ethernet.localIP());
}
void loop()
{
// command received (one character) '1' - activate garage door button
char cmd = 0; // 1 - pulse button

// listen for incoming clients
