ESP8266 Wifi statisch ip adres
Ik ben nog niet zo heel erg thuis in de Arduino code, maar maak gebruik van de voorbeelden die erbij zitten.
Momenteel heb ik een webserver draaien vanaf een SD kaart op een Arduino met een Wifi chip.
De Arduino krijgt nu een ip adres van de DHCP server, maar ik wil een vast IP adres toekennen. wat moet ik doen om een vast ip adres aan deze Wifi chip te geven ?

Re: ESP8266 Wifi statisch ip adres
De code is duidelijk, bedankt voor de link.
Ik zit er echter mee in welk bestand ik dit moet zetten.
Ik heb het voorbeeld script gebruikt waar de ESP8266 aansturing in zit en de SD-kaart.
Bovenaan dit script wordt het volgende aangeroepen:
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
#include <SPI.h>
#include <SD.h>
Waar moet ik nu het statische adres in opgeven ?

Re: ESP8266 Wifi statisch ip adres
In je eigen sketch
Re: ESP8266 Wifi statisch ip adres
Na het plakken van de code in mijn sketch krijg ik de volgende melding:
'WiFi' does not name a type
'WiFi' does not name a type

Have a FAT Formatted SD Card connected to the SPI port of the ESP8266
The web root is the SD Card root folder
File extensions with more than 3 charecters are not supported by the SD Library
File Names longer than 8 charecters will be truncated by the SD library, so keep filenames shorter
index.htm is the default index (works on subfolders as well)
upload the contents of SdRoot to the root of the SDcard and access the editor by going to http://esp8266sd.local/edit

Re: ESP8266 Wifi statisch ip adres
Je moet die regels wel in jouw sketch verwerken. Een deel moet bovenaan --- NA DE INCLUDES ---- en een deel in de setup -- OP DE PLEK VAN wifi.begin( etc.
Wat, heb ik al een paar posts terug gezegd.
