Hilfe beim Programmieren mit Arduino

HauptstadtRocker

Soo ich habe es mal schnell kompiliert und das ist der Fehler.

Er wird in Zeile 20 angezeigt:

PubSubClient.h ist auch vorhanden…. hmmpppfff ich verstehe nur noch Bahnhof.... auweia~~

Thisoft

Tja, ja - ein kleiner Tippfehler bzw. vergessen umzuschreiben. Du musst die folgende Zeile:

  Null_String.toCharArray(message_red, Null_String.length()+1);

durch diese ersetzen:

  Null_String.toCharArray(message_color, Null_String.length()+1);

HauptstadtRocker

soo ich habe es mal geändert leider immernoch ein fehler… bzw. denke es ist der selbe

es tut mir echt leid das ich dich damit so belaste… leider kann ich es nicht alleine.... :cry:

Thisoft

Kannst dich trösten - es ist nicht der gleiche Maßgeblich in der Fehlermeldung ist diese Zeile:

ws2812_iobroker:194: error: 'ip' was not declared in this scope

       IPAddress localAddr = ip;

ersetze mal die Zeile durch:

IPAddress localAddr = WiFi.localIP();

Da bin ich mir allerdings nicht 100%ig sicher da ich immer feste IP's verwende. Falls das nicht klappt schreibe mal testweise:

IPAddress localAddr = { 255, 255, 255,255 };

btw. - hast du in der folgenden Zeile die Adresse deines MQTT-Servers eingetragen?

//// MQTT-Settings
IPAddress mqtt_server(192, 168, xxx, xxx); // IP-MQTT-Broker

@Thisoft

leider hatte ich sehr wenig Zeit das nocmal zu testen. Jetzt sitze ich seit heute morgen daran und komme nicht weiter. Ich habe immer noch einen Fehler oder sogar mehrere. Ich kann verstehen wenn du mir nicht mehr helfen willst und aufgibst. Ich bedanke mich bis hierher auf jedenfall sehr bei dir. Solltest du doch noch lust haben hier mal mein Fehler den ich noch habe:

Habe ich gemacht! keine Änderung leider

  ` > btw. - hast du in der folgenden Zeile die Adresse deines MQTT-Servers eingetragen?
>

Auch das heb ich eingetragen und trotzdem keine veränderung :-(

Wenn Du das kompilierst geht das ohne probleme durch?

Thisoft

Warum sollte ich dir denn nicht mehr helfen wollen? Ist doch kein Problem. KAnn nur sein dass ich zwischendurch auch mal den Überblick verliere

Jetzt mach mal noch einen Versuch indem du den kompletten Abschnitt "////MQTT-Settings" durch das Folgende ersetzt. KAnn sein dass eigentlich nur die Zeile "WiFiClient client;" gefehlt hatte…

//// MQTT-Settings
IPAddress mqtt_server(192, 168, xxx, xxx); // IP-MQTT-Broker
const char* mqtt_username = "ioBroker"; // MQTT-User
const char* mqtt_key = "iobroker"; // MQTT-Password
WiFiClient client;
PubSubClient mqttClient(mqtt_server,1883, client);

Wenn das jetzt auch noch nicht hilft dann poste bitte wieder die Fehlermeldungen und dazu bitte den momentanen Code dass ich erstmal wieder "auf Stand" bin.

HauptstadtRocker

ich bin mir nicht sicher aber ich glaube es ist schon besser aber leider noch ein fehler drin

Sieht doch schon besser aus.

Dann lasse vorerst mal die Zeile

mqttClient.setCallback(callback);

ganz raus bzw. kommentiere die aus.

Weiterhin anstelle der Zeile:

#define BASE "RGBbyESP"

diese

const char* BASE = "RGBbyESP"

Dann sollte die Sache erstmal laufen - allerdings ohne den Arduino steuern zu können…
