Leave an empty [project_name].ino in the project. We can't distinguish between standard VC++ and Arduino without it.

nb: With a project_name.cpp. the .ino does not have to be empty but anything in it will be ignored.

The vcxitems is a standard vc++ shared project. We do create them and add files to them to make life easier for users but you are able to create them manually using std. visual studio commands.

The best way to create them for specific library versions is to install the required version of a library and use the visual micro "add library" menu with "clone" and "version" enabled.

I am not sure you really needed the complexity of the .cpp only project.

You seem to suggest you want two versions of your firmware. One for wifi devices and one for non-wifi.

Considering that the mcu has wifi on board you could leave the libs included and then only initialise and use the wifi when you need to.

Regardless of the route you choose an #include is going to be included in the compile. I think any discussion of switching of library detection would be misleading. It appears that you just need to not #include some headers under certain conditons.

If you really want to exlude code from a compile you can use compiler directives:- #if

#ifdef WIFI_ALLOWED
  #include "blah/h"
#endif
 

You can add your own configurations to the list of configurations on the tool bar. You will see the default shows Debug and Release configuration. Drop the list down to add your own.

The docs show how to add a "configuration specific" define. There are also global defines if needed but configuration specific allows a single source code to be built into different firmwares just by changing the selected configuration.

Does this help?

Sounds like you have switched off deep search for libraries. Switch it back on because it uses GCC to find included libs.

Thanks, we have replicated the problem with the .interim when using your own .cpp. We will look into it and fix over the next 48 hours.

To switch off prototypes in the current version that you are using you can add a board.txt to the project. Use "Add Code>Local Board.txt" menu or create one yourself. Add this setting into it:-

vm.ctags=false 

Hi Tim,

is there any news on this ?

I am using the latest VMicro version.

- Create a new project.
- Add a new .cpp file using the same name as the project.
- Compile :

Working with the latest version, current activity is solving an issue in the esp8266 MDNS library. :

Create new project MDNS_Issue.ino
Add MDNS_Issue.cpp to project (which includes setup & loop) -> Compiles OK.
Show/Hide Hidden files show src\core\...

Add #include <ESP8266WiFi.h> and #include <ESP8266mDNS.h> to MDNS_issue.cpp

Compiling -> Both libraries are compiled, so added to the project 

I prefer : Do not add at all, just have the compile have "not found .h file", so I can add the correct library, I might have a local library which I need to use.

Show/Hide Hidden files shows only core, no libraries.

Add code to use the library : WiFi.mode(WIFI_AP_STA);
Compiles OK.
Intellisense on the mode method only finds declaration, not definition

Add Libray esp8266WiFi library using "Create shared project when including libraries"
ESP8266WiFi library shows up as shared project, show/hide hidden files only shows core.
Compiles OK
Intellisense on the mode method finds both declaration and definition.


One additional : 
When, in solution exporer, I use the "Show All Files" to see the actual files & directories.
Then the core files all show up in the "top project directory", mixing with the actual project files.
Would expect to show up in a directory or not at all (they are not in the actual directory)

That is what I expected. But they do not.
