I cannot get this to run. I am new to B4R but not to programming. How do I add this library? I get a missing reference error related to the library. This is my first time using the product. Any help would be greatly appreciated.

Please post the exact error message.

How do I add this library?

1. Configure the additional libraries path under Tools - Configure Paths.
2. Extract the zip file and copy its content to that folder (keep the folders structure).

Got past the issue I just posted but now I am hitting this issue.

And thanks very much for your previous reply.

Do you see this file in the library folder:

?

It looks like it might be one level down, not in the same place as your screen shot. Is that the case?

1. Delete these 4 files and the xml file.
2. Create a new folder named c:\B4RLibraries
3. Configure the IDE to use it (Tools - Configure Paths).
4. Copy the xml file and the folder to c:\B4RLibraries.

 

[william235]

copied it to one level up and still same error

Do you see this file under: C:\Users\William\Desktop\B4R Libraries\Objects\src\ ?

Try to clean the project by clicking on Ctrl + P.

I apologize that I have wasted your time. I got it. Though I created the libraries as you suggest they were incorrectly configured. I got the code running. Thanks very much for your responses. I look forward to getting into this application.

Best regards,

V1.10 is attached to the first post. It is based on the latest version of sparkfun library. It fixes the issue with incorrect values returned.

Perfect!!!!!! Thanks so much. I was able to get the hardware running with the Arduino SFE library. Now this works as well. I much prefer this programming environment.
