  Fade for c-info wall at c-base.
  Works with TI's connected launchpad and the IDE.

// Apparently the preprocessor variables B0 and B1 are already taken.
// Therefore we use the prefix CBASE

#define CBASEG1 PL_5
#define CBASEB1 PM_1

#define CBASER2 PM_7
#define CBASEG2 PA_7
#define CBASEB2 PM_6
