Arduino UNO (NANO) + W5500 + 8 Realy

Всем привет. Ищу того кто оптимизирует код чтобы он работал на Arduino UNO или NANO. Оригинал кода взят с

Весь софт что я заказываю выкладываю на своём канале так что если нужно прорекламирую канал или группу исполнителя и софт будет доступен всем бесплатно. Но я не прошу сделать задаром просто нужен тот кто сделает за разумную цену.
из железа Arduino UNO и NANO CH340 и FTDI модуль W5500 маленький без карты памяти.

В пол глаза посмотрел.
Получается много свободной пзу, мало озу.
Значит 1-ое что надо сделать все текстовые константы вместо "On" записать как F("On") Это прилично освободит озу.
Изменив таким образом 4 строки (56-59) я освободил ~10% Озу. Работа механическая и умения программировать не требует. Могут быть затыки , где идет сложение строк - просто пока пропустить эти места.

2-ое. Не хранить состояние реде в строках. Ну что за боред ? Хранить состояние 8 реле можно в 1-ом байте. Каждый бит либо 0 либо 1. 0-выключено , 1 включено. И если нужен текст - написать маленькую функцию. 8 реле по 4 байта на строку (off+0) это 32 байта вместо 1-го. Не много. но курочка по зернышку.

@Levvarrr, привет
веб сервер отрисовывает кнопки под номерами 0 2 4 6 ну как бы вот так

Эх.... Пришлось проверять. Напрягаться

Нашел у себя W5500.
Все работало правильно. Кавычек не хватало. + еще подправил код в одном месте и выкинул еще лишнюю хрень.

C++:

#include <SPI.h>
#include <Ethernet2.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 21);
EthernetServer server(80);

bool relayState[8] = {0, 0, 0, 0, 0, 0, 0, 0};
byte relay[8] = {2, 3, 4, 5, 6, 7, 8, 9};

char linebuf[80];
int charcount = 0;

void setup() {

  for (byte i = 0; i < 8; i++)
  {
    pinMode(relay[i], OUTPUT);
    digitalWrite(relay[i], HIGH);
  }

  Serial.begin(9600);

  Ethernet.begin(mac, ip);
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
}

void dashboardPage(EthernetClient &client) {
  client.println("<!DOCTYPE HTML><html><head>");
  client.println("<meta name=\"viewport\" content=\"width=device-width, initial-scale=1\"></head><body>");
  client.println("<h3>Arduino Web Server - <a href=\"/\">Refresh</a></h3>");
  for (byte i = 0; i < 8; i++) {
    client.println("<h4>Relay " + String(i) + " - State: ");
    if (relayState[i] == 0) {
      client.println("Off</h4><a href=\"/relayon=" + String(i) + "\"><button>ON</button></a>");
    }
    else if (relayState[i] == 1) {
      client.println("On</h4><a href=\"/relayoff=" + String(i) + "\"><button>OFF</button></a>");
    }
  }
  client.println("</body></html>");
}

void loop() {
  EthernetClient client = server.available();
  if (client) {
    Serial.println("new client");
    memset(linebuf, 0, sizeof(linebuf));
    charcount = 0;
    boolean currentLineIsBlank = true;

    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        linebuf[charcount] = c;
        if (charcount < sizeof(linebuf) - 1) charcount++;

        if (c == '\n')
        {
          byte temp = 0;
          sscanf((char *)linebuf, "%*[^0-9]%d", &temp);

          if (strstr(linebuf, "relayoff") > 0)
          {
            digitalWrite(relay[temp], HIGH);
            relayState[temp] = 0;
          }
          if (strstr(linebuf, "relayon") > 0)
          {
            digitalWrite(relay[temp], LOW);
            relayState[temp] = 1;
          }
          dashboardPage(client);
          break;
        }

      }
    }
    delay(1);
    client.stop();
  }
}

Как я понял из комментария на ютубе. Ты хочешь еще и кнопки прикрутить к этому делу. И при нажатии кнопки не только срабатывало реле, но и обновлялась страничка в браузере.
Это все реализуемо. НО я сомневаюсь что у тебя это получится. (Ведь изначально ты даже циклами не пользовался для упрощения кода).
Для реализации подобной задумки требуется знание HTML,JS и CSS что бы все приукрасить.
Для начало посмотри цикл этих роликов:

В них есть все для старта.
Еще проблема в отсутствии места на МК. На мегу328 в принципе все это залезть сможет. Но желательно писать код уже на С.
ЗЫ: Подправь IP и Библу Ethernet
