This project provides a Web Server Framework using either the Arduino Wifi Library or the EspressIf SDK API.
Setup:
- Copy the web_server folder to your Arduino sketch folder.
- Copy the UtilityFunctions folder to your Arduino libraries folder.
- Copy the webserver folder to your Arduino libraries folder.
- Change the following in the web_server sketch to match your network settings:
const char* ssid = "YOURWIFISSID";
const char* password = "YOURWIFIPASSWORD";
const IPAddress ipadd(192,168,0,132);
const IPAddress ipgat(192,168,0,1);
define SVRPORT 9701
5.0 Server Setting
5.1 To use the standard Arduino Web Server library, which polls for connections, use this define in the sketch:
define SVR_TYPE SVR_HTTP_LIB
5.2 To use the EspressIf SDK Web Server API, which uses event callbacks, use this define in the sketch:
define SVR_TYPE SVR_HTTP_SDK
Operation:
While not necessary, the code assumes an LED is connected to GPIO16. This LED is ON upon power-up and is turned OFF once initialization completes.
Web Server test:
Enter the following URL in a web browser (adjust IP & port to your settings):
http://192.168.0.132:9701/?request=GetSensors
A JSON string will be returned with the sensor values in this format:
{ "Ain0":"316.00", "Ain1":"326.00", "Ain2":"325.00", "Ain3":"314.00", "Ain4":"316.00", "Ain5":"163.00", "Ain6":"208.00", "Ain7":"333.00", "SYS_Heap":"25408", "SYS_Time":"26" }
The server will also respond to requests to turn the LED, if connected, on and off.
To turn on, enter the URL:
http://192.168.0.132:9701/?request=LedOn
To turn off, enter the URL:
