Charlieplexing Library

[robrlstn]

I've got the TinyShield 16 Edge LEDs board working (please see the short TinyDuinoEdgeLeds clip at:http://www.youtube.com/user/robrlstn/videos.

Code is modification of example on TinyCircuits tutorial page.

PROBELM:  I cannot get the Charlieplexing Library to work at all. I have downloaded that library, put it unzipped into the Arduino/libraries folder, and imported the Library so I can get the #include <Charlieplex.h> statement added to a sketch.

But the example included with that library, SimpleCharlie.pde, will itself not compile, throwing many errors with Arduino 1.0.5.

As an Arduino newbie, I cannot troubleshoot the meaning of these errors. So I cannot tell if I'm doing something wrong or that library has problems.

Thank you in advance for any help.  Robert

Ok, I think I figured this out (but not yet extensively tested).

The example included with the Charlieplex library, SimpleCharlie.pde, now compiles and runs. Also, a simple program I wrote now also runs using that library.

The problem was in the header file, Charlieplex.h.  In there, I changed the statement #include <wProgram.h> to #include <Arduino.h>, following the 'Writing a Library for Arduino" article.

Apparently, this change, from wProgram.h to Arduino.h was made in some earlier version of the Arduino code.
