Zusammenfügen zweier Codes ESP32 Smart Home Control

lolo5015 · April 23, 2023, 4:45pm

Hallo ich habe hier zwei Codes die ich gerne zusammenfügen möchte. Leider kommt immer der Fehler wenn ich diese zusammen füge: conflicting declaration 'WebServer server'.

Hier sind die beiden Codes:

#include <WiFi.h>
#include <Adafruit_NeoPixel.h>

const char* ssid = "";           //Netzwerk Name
const char* password = "";            //Netzwerk Passwort

WiFiServer server(80);

#define Steckdose_PIN 22
#define LED_PIN    23
#define LED_COUNT 300

Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
uint32_t red = strip.Color(255, 0, 0);
uint32_t green = strip.Color(0, 255, 0);
uint32_t blue = strip.Color(0, 0, 255);
uint32_t white = strip.Color(255, 255, 255);
uint32_t yellow = strip.Color(227, 235, 7);
uint32_t orange = strip.Color(235, 151, 7);
uint32_t lila = strip.Color(235, 7, 201);
uint32_t cyan = strip.Color(5, 240, 208);

Alles was mit WLAN zu tun hat nur einmal machen.

Rentner · April 23, 2023, 4:55pm

Hallo,
na ja so einfach ist das nicht, Du kannst nicht nur einfach was zusammen kopieren. Es kann nur ein Setup und nur ein loop geben.

Du kannst aber das bei dem zweiten Code umbenennen und im ersten aufrufen.
alle include in den ersten packen
Achtung globale Variable checken damit sie nicht doppelt vorkommen , eventuell umbenennen

eventuell auch einen zweiten Tab nutzen

Du kannst auch hier im Forum mal suchen , die Frage taucht alle paar Wochen mal auf , und es gibt sicher Beispiele hier und Hilfen

lolo5015 · April 23, 2023, 5:08pm

das ist schon klar. ich habe alles in die jeweiligen voids kopiert und der Fehler kommt bei der Zeile wo ich den WebServer server (80); und WiFiServer server (80); zusammen mache. liegt wahrscheinlich an der WiFi.h und WebServer.h Bibliothek

Rentner · April 23, 2023, 5:12pm

Und warum sehe ich dann z.B zweimal setup und 2 mal loop in Deinem code.

wie sollen wir das denn teste , so gehts nicht das muss sich keiner irgendwo reinkopieren .

Ganz sicher nicht, sondern es liegt an deinem Sketch den du uns hier zeigst.

fony · April 23, 2023, 5:40pm

Dan schau hier
Nicht vergessen Augen aufmachen und oder Brille putzen
Schreibe uns was dort für Bibliotheken benutz werden, und vergleiche deine Duplikate

Hallo,

die beiden Sketche beruhen auf 2 unterschiedlichen Methoden einen Webserver zu bauen.

Ich denke das wird so nichts werden. Man müsste den zweiten so umbauen das er auch auf den gleichen Methode, unter Nutzung der webserver.h beruht und die gleiche Funktionalität bereitstellt. Das ist eigentlich die beste und empfohlene Methode für einen ESP
Ich lasse mich aber gerne eines besseren belehren.

Eventuell hat ja sonst noch jemand eine andere Idee. Ich bin da jetzt raus.

@Rentner war schneller
Du versuchst 2 unterschiedliche Server zusammen kleben das geht nicht.
Der einer ist im Format client.println(), der zweiter ein text/html einen must du umschreiben. Im jedem Fall so wie das ist wird nicht gehen, so sehe ich das, wehre schön wen ich unrecht hatte

fony · April 23, 2023, 8:17pm

Ich sehe auch keine andere Möglichkeit.

Rentner · April 23, 2023, 8:20pm

Hallo
@fony da wird der TO doch etwa tiefer einsteigen müssen als wie vorgesehen

Gruß Heinz

Tommy56 · April 23, 2023, 8:22pm

Es gäbe evtl. eine dreckige Variante, von der ich allerdings auch abraten möchte:
Alle "server" aus dem 1. Code in wserver umbenennen und dann neu zusammen fügen. Das sollte zumindest kompilieren, sinnvoll ist es nicht. Ob es funktioniert ist auch nicht sicher.

Gruß Tommy

fony · April 23, 2023, 8:24pm

Bin kein HTML Mensch, nehme Beispiele und passe die an.
Wo bei der Konstrukt mit client.println(), ist sehr einfach aber hat seine Grenzen

Gruß Bernhard

Rentner · April 23, 2023, 8:26pm

@Tommy56 gute Idee das könnte klappen , ob's dann stabil läuft kommt auf einen Versuch an dann gibt's quasi 2 Webserver auf einem System

Gruß Heinz

fony · April 23, 2023, 8:27pm

Also da wurde mir was bei Fips klauen und neu schreiben, die Arbeit ist gleiche und wurde funktionieren.

Gruß Bernhard

fony · April 23, 2023, 8:30pm

Weis nicht, ist wie Quadrat in Kreis formen.

Gruß Bernhard

Tommy56 · April 23, 2023, 8:30pm

Nicht klauen, sonder nutzen. Die Codes von Fips stehen unter LGPL. Ansonsten gebe ich Dir Recht.
Das setzt aber voraus, dass der TO sich wenigstens minimal mit der Problematik beschäftigen will oder nur C&P machen will (was meist schief geht und viel mehr Zeit beansprucht, aber leichter aussieht).

Gruß Tommy
