Basic Web Skeleton (LTS)


This is a copy of the Basic_WebSkeletonApp from the Sming LTS branch, modified to build for Sming 4.0. Sming uses ArduinoJson version 6 by default, so this sample demonstrates how to continue using version 5.

This is how it was done:

  1. When including SmingCore.h, just use #include <SmingCore.h>.

  2. Remove the file include/user_config.h. Sming provides this by default, but if you have made changes for your project then remove everything except your changes, but be sure to add #include_next <user_config.h> at the top.

  3. Remove any #include <user_config.h> statements from your files. This file is automatically included by Sming.

  4. Rename file to

  5. Replace the file Makefile with the one from the Basic_Blink sample project. If you’ve ignored the instructions and modified the file (!) then you’ll need to move those changes into your new file instead.

  6. Sming uses #pragma once style for header guards, so consider updating your own files if you’re not already doing this.

  7. We use the OneWire Arduino Library, so add ARDUINO_LIBRARIES := OneWire to our file. Sming now only builds libraries which are specifically requested for a project.

  8. We’re using ArduinoJson, version 6. Sming supports version 5 or 6, but you must specify which one:

    • Add ARDUINO_LIBRARIES=ArduinoJson6 to the project’s file.

    • Add #include <JsonObjectStream.h>. If you’re not using the stream class, add #include <ArduinoJson6.h> to code.

  9. Update callback function parameter lists for STADisconnect and STAGotIP. We can also get a description for disconnection reasons, so display that instead of just a number. See Sming/Platform/WifiEvents.h.

  10. In webserver.cpp, the onConfiguration() function uses request.getBody(). It is more efficient to use streams, so just replace with request.getBodyStream().

That’s it.
