Compiling and Loading to Wemos D1

It is recommended to use Arduino IDE. You will need to configure Arduino IDE to work with the Wemos board and USB port and installed the required USB drivers etc.

• USB CH340G drivers: https://wiki.wemos.cc/downloads
• Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas. This will add support for the Wemos D1 Mini to Arduino IDE.
• Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
• Select Board: "WeMos D1 R2 & mini"

Loading Supporting Library Files in Arduino

Use the Arduino guide for details on how to installing and manage libraries https://www.arduino.cc/en/Guide/Libraries
Packages -- the following packages and libraries are used (download and install):
<ESP8266WiFi.h>
<ArduinoJson.h> --> https://github.com/bblanchon/ArduinoJson (version 5.13.X)
<ESP8266WebServer.h>
<WiFiManager.h> --> https://github.com/tzapu/WiFiManager
"FS.h"
<SPI.h>
<Adafruit_GFX.h> --> https://github.com/adafruit/Adafruit-GFX-Library
<Max72xxPanel.h> --> https://github.com/markruys/arduino-Max72xxPanel
<JsonStreamingParser.h> --> https://github.com/squix78/json-streaming-parser

Initial Configuration

Starting with version 2.0 editing the Settings.h file is optional. All API Keys are now managed in the Web Interface except for the GeoNames Key. It is not required to edit the Settings.h file before loading and running the code.

• Open Weather Map API Key: http://openweathermap.org/
• News API Key: https://newsapi.org/
• GeoNames Key (optional as you can use mine or create your own) http://www.geonames.org/ -- this key is only managed in the Settings.h file.
• Your OctoPrint API Key (optional if you use the OctoPrint status)
• Version 2.0 supports Chained 4x1 LED displayes -- configure in the Settigns.h file.

NOTE: The settings in the Settings.h are the default settings for the first loading. After loading you will manage changes to the settings via the Web Interface. If you want to change settings again in the settings.h, you will need to erase the file system on the Wemos or use the “Reset Settings” option in the Web Interface.

Web Interface

The Marquee Scroller uses the WiFiManager so when it can't find the last network it was connected to it will become a AP Hotspot -- connect to it with your phone and you can then enter your WiFi connection information.

After connected to your WiFi network it will display the IP addressed assigned to it and that can be used to open a browser to the Web Interface. You will be able to manage your API Keys through the web interface.
The default user / password for the configuration page is: admin / password

The Clock will display the time of the City selected for the weather.

Donation or Tip

Please do not feel obligated, but donations and tips are warmly welcomed. I have added the donation button at the request of a few people that wanted to contribute and show appreciation. Thank you, and enjoy the application and project.
