Mux Shield error on example

Former Member

Hello everyone,

I've bought a Mux Shield II and I'm trying to test it on an Arduino Mega 2560.

 

I've downloaded the libary and put in libraries folder just exactly how it's explained into User Guide,

 

The error is in the initializing  of the shield:

How you can see from the image, the shield is not even recognized as type of variable.

In userGuide I can find:

I've also tried to implement:

MuxShield() muxShield;

using the parentesys but I got the same error.

 

Can someone help me?

Thank you very much!!!

  • Alessandro,

                        are you certain you decompressed the library before you installed it?  The error you are getting seems to indicate that your code cannot find the library.  I would uninstall both versions and then re-install from scratch.  I am not certain how the double library set up would work as I have never done it.  I am not certain of the precedence the Ardino IDE and tool chain give to library locations but I have had problems with libraries clashing when they contains similarly named files.  i.ei the library can see two files with the same name within the collective libraries folder.  On my set up I have a folder under the C:\ directory called Arduino sketches, under that directory is another one called libraries.  That works OK for me.  I use Arduino IDE version 1.5.8 and that is under the Windows programs86 directory.

     

    If you are certain the library is installed properly then I would check the names in the header (.h) file for the library.

     

    I hope that helps

    My experience with having a library in twice is it starts to give errors but not stating the real problem, I cannot remember the exact error and im not in a position to try right now

     

    Suffice to say… don’t do it and simply renaming the folder that one of the libraries is in will not fix the problem

     

    You need to completely remove it from its search paths

    Thank you all guys,

    I removed the double library folder and just put it into Programs> Aduino>libraries

    Then I REMOVED THE FOLDER "_MACOSX"....

    So from:

         Programs> Aduino>libraries>MuxShield>_MACOSX

                                                                      MuxShield

     

    It got:

          Programs> Aduino>libraries>MuxShield

     

    Now the sketch works... Thank you very much all!
