Thanks for bringing this to our attention.  It appears that the location of the Wire library source files was changed in 1.6.8, although there is no mention of it in the Arduino IDE release notes.  The source files are now at \Arduino\hardware\arduino\avr\libraries\Wire\src instead of in the root Wire lib folder.  I created Case 133 to track this issue and we will hopefully have a fix in the next release.  For now here is a workaround:

In \Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\Aledyne-TSXperts\Arduino Compatible Compiler for LabVIEW\Arduino Libraries\LiquidCrystal\I2CIO.cpp

CHANGE:

#include <../Wire/Wire.h>

TO

#include <Wire.h>

Is this forum not a working forum anymore?

Sorry for the late reply, yes it is still active but your initial post on this thread got missed.  Sorry about that.  I suspect that your Arduino sketchbook path is not pointing to the Libraries directory so the Arduino compiler cannot find the LCD.h header file that is part of that library.  Open the Arduino IDE and go to File>Preferences and make sure sketchbook location is set to:

C:\Users\[USERNAME]\Documents\Arduino.

Let us know if that solves your problem.

The location is set to that directory. I get the same error.

I did some research on the LCD with shield I bought, and it is not a I2C display. So I cannot use the example code that came with the compiler.

 

Is there any sample Labview code that works for a standard 16X2 LCD.

 

Thanks

For the include problem, that is definitely an issue with Arduino finding the LiquidCrystal library.  Make sure it is located in the C:\Users\[USERNAME]\Documents\Arduino\Libraries\LiquidCrystal directory.

You can also take a look at this post for additional info:

https://forum.arduino.cc/index.php?topic=330766.0

 

There is currently no library for the parallel LCDs.  You would have to create one, which is possible using the"Porting an Arduino Library to the Arduino Compatible Compiler for LabVIEW" section of the user manual.  But this is an advanced feature and I would advise just buying an I2C 16x2 LCD, they are quite cheap and require much less I/O and wiring.

Thanks Steffan,

 

Would you have a recommendation on which display to buy?

Hi,

 

i have the same problem of griff 32! I have a 16x2 i2c lcd but I can't compile the example file cause I receive that error!

anyone solved it?

thanks everybody

You must have a typo in I2CIO.cpp.  Read your errors, it tells you right there.  "uinte8_t" is not a valid datatype.  It should be "uint8_t".

Thank Steffan, I changed  "uinte8_t" into "uint8_t", the build is successful, but "DPI detection failed,fallback to 96 dpi".

That looks related to you monitor settings and the Arduino IDE, nothing specific to the Compiler.  Might be able to just ignore it but search online.  I found this link for starters.

I still don't understand. IDE's build is OK. I installed Arduino IDE 1.6.9 last. It's OK.

This problem still seems to exist. I'm surprised it hasn't been resolved yet. This appears to render all of the I2C LCD VI's useless.

Same issue as griff32 and miche91...

1.0.0.21, Arduino/Genuino Mega or Mega 2560

Initializing packages...

 #include "LCD.h"

                 ^

compilation terminated.

exit status 1
Error compiling.

The sketchbook location is definitely set to C:\Users\Greg\Documents\Arduino in the preferences.

It appears that when the compiler runs it is looking for various files in that cryptic temp directory - but they are not getting copied there. I tried rolling back to Arduino IDE 1.6.7 but that didn't help...

Any suggestions would be most welcome. I have a project that I really need the I2C LCD display for.

The temp directory will not contain the source files.  This particular header file is part of the Liquid Crystal library.  Look in "C:\Users\Greg\Documents\Arduino\Libraries\LiquidCrystal" and this is where LCD.h should be.  If it is there, then you must have an IDE configuration issue. Here is a reference describing common issues with libraries.  You can also try compiling a simple Arduino example using the same header file and you should get the same error, which tells you it is an issue with the Arduino IDE.

OK, thanks. I do get the same error in the Arduino IDE. The multiple locations of the libraries is quite confusing. They are located in

C:\Users\[Username]\Documents\Arduino\libraries

also

C:\Program Files (x86)\Arduino\libraries

and also

C:\Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\Aledyne-TSXperts\Arduino Compatible Compiler for LabVIEW\Arduino Libraries

I guess I need to understand which are needed/used and under what circumstances.

Thanks again...

The one in the LabVIEW directory is expected.  The Compiler ships with it and copies to your C:\Users\[Username]\Documents\Arduino\libraries folder if it is not there already for convenience.  The Arduino IDE only checks from the 2 Arduino directories you mentioned.  The LCD.h should only be in the C:\Users\[Username]\Documents\Arduino\libraries related folder, not in the Program Files libraries folder.  You might want to try removing the duplicate library in the C:\Program Files (x86)\Arduino\libraries folder.

Steffan,

I got it to work in the Arduino IDE by using a third party LiquidCrystal_I2C library and then included that in my sketch.

One more question... What is the purpose of the "Copy Libraries.vi" in the

C:Program Files (x86)National InstrumentsLabVIEW 2014vi.libAledyne-TSXpertsArduino Compatible Compiler for LabVIEWArduino Libraries

folder?

Does the Labview Arduino compiler need a mirror of the Arduino libraries in this location? Do I need to run this vi to do this?

 

Thanks...
