GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

### Async TCP Library for ESP32 Arduino
This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP32 MCUs.
This library is the base for [ESPAsyncWebServer](https://github.com/dvarrel/ESPAsyncWebServer)
## AsyncClient and AsyncServer
The base classes on which everything else is built. They expose all possible scenarios, but are really raw and require more skills to use.

# GPIOViewer Arduino Library to see live GPIO Pins on ESP32 boards
**Transforms the way you troubleshoot your microcontroller projects**.
### Youtube Tutorial
[<img src="https://github.com/thelastoutpostworkshop/images/blob/main/GPIO%20Viewer.png" width="300">](https://youtu.be/UxkOosaNohU)
### Installation Arduino IDE (Version 2)
> Make sure you have the latest ESP32 boards by Espressif Systems in your Board Manager<br>
- Install the **GPIOViewer Library with the Arduino IDE Library Manager** or Download the [latest release](https://github.com/thelastoutpostworkshop/gpio_viewer/releases/latest) and install the library in the Arduino IDE : `Sketch > Include Library > Add ZIP Library...`
- Download [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer) and install the library in the Arduino IDE `Sketch > Include Library > Add ZIP Library...`
- Install the the [AsyncTCP](https://github.com/dvarrel/AsyncTCP) using the Arduino IDE Library Manager.
### Installation VSCode + PlatformIO
Add the following to your platformio.ini file:
```
lib_deps =
https://github.com/dvarrel/AsyncTCP.git
https://github.com/me-no-dev/ESPAsyncWebServer.git
https://github.com/thelastoutpostworkshop/gpio_viewer.git
```
### Usage
> You can also use get examples provided with the library in the Arduino IDE through the menu `File > Examples > GPIOViewer`<br>
> You only need to include the library, declare the GPIOViewer and call begin() at the end of your setup, and that's it!<br>
> The URL to the web GPIO viewer application is printed on the serial monitor<br>
```c
#include <gpio_viewer.h> // Must me the first include in your project
GPIOViewer gpio_viewer;
void setup()
{
Serial.begin(115200);
// Comment the next line, If your code aleady include connection to Wifi
gpio_viewer.connectToWifi("Your SSID network", "Your WiFi Password");
// gpio_viewer.setPort(5555); // You can set the http port, if not set default port is 8080
// Your own setup code start here
// Must be at the end of your setup
// gpio_viewer.setSamplingInterval(25); // You can set the sampling interval in ms, if not set default is 100ms
gpio_viewer.begin();
}
```
> The default HTTP port is **8080** and default sampling interval is **100ms**.
### GPIO Supported
- Digital
- Analog
- PWM
### Library Size
- The GPIOViewer Library adds 50 KB to your projects.
- No worries! All the assets (ex. board images) of the web application are loaded from github pages and don't add to the size of your projects.
### Performance
- Ensure you have a strong Wifi signal with a good transfer rate. 25ms sampling interval works great on Wifi 6 with 125 Mbps.
- If you get "ERROR: Too many messages queued" on the Serial Monitor, this means the data is not read fast enough by the web application. The data will still be displayed, but with some latency. Reduce the sampling interval or try to improve your Wifi performance.
### ESP32 Boards Supported
> You can use the "Generic View" in the GPIO Web Application to see GPIO pin activites live even if your board image is not listed <br>
> You can also request an ESP32 board image addition by [creating a new issue](https://github.com/thelastoutpostworkshop/gpio_viewer/issues).
