Publish / Share / Register your own library in PlatformIO Library Registry

Step 1: publish your project on github

You must first create your manifest file that must be called "library.json" and it must be in the root of the project

In my case it has the following structure:

{
  "name": "EasyOta",
  "keywords": "ota, over,to, air,esp8266",
  "description": " The easiest way to implement ota on an esp8266 based chip using an HTTP server",
  "repository":
  {
    "type": "git",
    "url": "https://github.com/Eitol/EasyOta.git"
  },
  "authors":
  [
    {
      "name": "Hector Oliveros",
      "email": "hector.oliveros.leon@gmail.com",
      "maintainer": true
    }
  ],
  "license": "MIT",
  "version": "1.0",
  "frameworks": "arduino",
  "platforms": "espressif8266"
}

Step 2: copy the url of the raw project

The url is some like this:

https://raw.githubusercontent.com/GITHUB_USER/PROJECT/master/library.json

Example:

For my project with url = https://github.com/Eitol/EasyOta

Then, the url is:

https://raw.githubusercontent.com/Eitol/EasyOta/master/library.json

Step 3: Use the url to register your library

The command is:

platformio lib register [MANIFEST_URL]

example:

platformio lib register https://raw.githubusercontent.com/Eitol/EasyOta/master/library.json

FIX: No output from qDebug

Si qDebug no muestra nada en Qt 5.9 entonces debes crear un fichero qtlogging.ini (vacio) en el directorio home: 

.config/QtProject/qtlogging.ini

Raspberry PI 3 Composite video problem

Si conectando la raspberry al television usando un cable plug - RCA ves una imagen como la siguiente:

es porque el cable que estas usando no es el adecuado y tiene intercambiado el pin de tierra con el de video:

Solución:

Solución cara pero fácil: Comprar un cable que sea compatible que transmita el video por el último segmento (como los de Apple)

Solución fea: Soldar los cables a la rb: https://www.raspberrypi.org/forums/viewtopic.php?t=181288

Solución fácil y barata:  Con un conector dc hembra y otro macho puedes pasar intercambiar la señal de video por la de tierra (Esta me funcionó perfecto)
