Wire library (I2C) not compiling (linking problem ?) #10

Closed JBChossat closed 9 years ago

JBChossat commented 9 years ago

Wire library does not compile in sketch although this library is supposedly ported for the Freesoc2 board. It seems that there is some linking problem during compilation because wire was written in C++ ? Library added using the native arduino IDE: Sketch-> Include library->Wire. Adds following includes in the code:

include

include

Rest of the code is empty.

I (apparently) added a file without protecting an include.

It's fixed, now, in V 0.1.2.
