Insufficient Memory Error

I've got Visual Micro 1.1505.19 installed for Visual Studio Community edition.
If I try to do a Peek Definition on analogRead, I get an Error: Insufficient memory to continue the execution of the program. Same for digitalRead, pinMode, etc.
The PC I'm using has 4GB RAM and no more than 75% of the RAM is in use.

When I'm in visual studio editing the ino file. If I right click on the analogRead function and select Peek Definition I get the error. If I select Go to definition, nothing happens.
I have an include file. The Adafruit NeoPixel library. If I right click on string.show() (for example) Peek Definition works.

Okay I see thanks.

All I can say is that I don't think Visual Micro is not involved with this issue. All Visual Micro does is to ensure that you have a correctly configured standard Microsoft C++ project with source locations and pre-processor definitions for the chosen Board/Platform.

Once the c++ is configured we leave the standard Visual Studio C++ intellisense engine to do whatever it does.

I can only guess (and probably wrongly) that you are out of memory. I am never sure if a hidden proportion of memory is used or reserved by MS or if the amount of free disk space also an effect.

What if you close a few other apps? Does the issue for away?

It's the only app running and I have 1.1GB free RAM.

I'll search around the Visual studio folks and see about intellisense errors. I'll let you know.

Odd. The Programs & features shows version 15.05.2400.
I'm going to uninstall visual micro, clear the addins from Visual studio, CCleaner the registry. Then re-install visual micro. Let's see if that helps.
A visial Studio posting I read about insufficient memory said an add-in may be the culprit.

I've got it fixed, but I'm not happy with the solution.
I created a new Arduiono project and pasted in my code from the original ino file.
It works now. However, when creating a new project, it doesn't give me a choice where to put it. It just creates it in my d:\users\<user>\documents\arduino-1.6.x\ folder

Hi,

1)
Great. If it happens again please switch to a different board and back to your required board. The change of board causes visual micro to reset intellisense (as does other things such as adding a library or saving .ino files that contain new methods). but first zip the sketch and email to info [at] visualmicro.com. I suspect that either a pre-processor def or an include path caused the intellisense to get confused. or it might simply be an infrequent vs2013 bug.

2)

Yes correct. This is how arduino works. It has something called a sketchbook folder which defaults to myDocuments\Arduino. You can change the path in the ide locations config window. The sketchbook is where arduino saves and loads sketches and also where custom libraries and hardware are stored.

If you take a look at the standard visual studio "File>New>Project" window in the C++ section you will find a new Arduino Project option which works how VS normally works. Both resulting projects are the same the only difference being you have access to change the location as you would normally expect with a VS project.

Will do. Thanks.

Oh, I've already been using the debug. It's awesome. Worth every penny.

I was looking at the project folder for the 1st and second projects I had. The project_1 folder has an SDF file (SQL Server Compact DB) that as 199MB, the seconf project (Same code) has an sdf file that was just 68MB. If I disable the DB (Tools->Options->Text Editor->C/C++->Disable Database) and delete the sdf file, Intellisense doesn't seem to work. If I then re-enable the DB, intellisense works again and there is no memory error. There is also an option to rebuild the DB (Tools->Options->Text Editor->C/C++->Rebuild Database). My memory error is now gone. The sdf file must have been corrupted.

Well found. I can't believe that Microsoft still has this issue. It was more of a problem for vs2008.

This will be useful for others so great post thanks
