1) For debug purposes i use chronos display to print information, may be
there are exist other ways to print debug information?
you could use the gdb with mspdebug[1]. Support for the cc430 works pretty
well.
2) Am i right, should i use cc110x module instead of the cc110x_ng?
In fact, you could use both, but the cc110x_ng does not include a MAC layer
implementation. Another advantage for the cc110x driver may be its maturity.
However, the cc110x_ng is smaller and neater.
