Ok, I have the latest Energia 0101E0013, but this library is not visible from there.
I cannot compile the example because "ADS1118.h: No such file or directory".
I found some ADS1118 library under "energia-0101E0013\hardware\c2000\libraries" but even this one does not correspond to the example I'm dealing with. At first glance in the ADS1118.cpp the following line is commented:
//#include <msp430g2553.h>
and this one is present:
#include "F2802x_Device.h"
There are other differences as well.
