B4R Library rESPUI for esp32

it is a wrapper for ESPUI from https://github.com/s00500/ESPUI but wrapper is working only for ESP32.

ESPUI is a simple library to make a web-based user interface for your projects using the ESP8266 or the ESP32 It uses web sockets and lets you create, and update elements on your GUI through multiple devices like phones and tablets.
ESPUI uses simple Arduino-style syntax for creating a solid, functioning user interface without too much boilerplate code.

So if you either don't know how or just don't want to waste time: this is your simple solution user interface without the need of internet connectivity or any additional servers.

in B4R, objects can be created without call back or with call back when an activation of a sub is needed from object modification.
in B4R, only one Callback is available and a sort of object at origin of call back is needed from userdata / controlType to activate a code from user action on object

full documentation in https://github.com/s00500/ESPUI
examples for B4R are provided in wrapper delivery

I'm trying the complete example, but i get this error. Seems some file are missing. Am I missing something?
Here the compilation logs.

[candide]

ESPUI.h not found
only wrapper rESPUI is in delivery B4R, ESPUI library have to be installed in arduino area.

 

[peacemaker]

ESPUI library have to be installed in arduino area

And it's dependencies

Hi,

After updating all Arduino libraries to the latest it fails. I tried copying the code from the GitHub repository and compile it in Arduino and it fails also there with this message:

Any insights on what can I do? Have you noted the versions of the libraries that are suitable for the ESPUI and consequently with rESPUI?
I compiled (tried to) the code in this: https://github.com/s00500/ESPUI/tree/master/examples/completeExample

ESP32 core is 3.3.8.

please to have a look here :

Latest ESP Async WebServer library breaks working sketches

I installed the Async TCP library v 3.3.8 and ESP Async WebServer 3.7.4., however my sketches (which work fine under ESP Async WebServer 3.7.2.) still won't compile. Here is the error message: In file included from...

forum.arduino.cc

this issue seems due to AsyncTCP" library, "Async TCP" library and ESP Async WebServer library conflict

in my case after AsyncTCP" library removed and "Async TCP" library installed and and "ESP Async WebServer" library installed (not an other) => compilation is OK with arduino and B4R

Thanks for the fix. It compiled flawlessly.
