The GoodWatch firmware is in this directory. You will find user-level
applications in the apps/ subdirectory, while *.c in the root
directory contain low-level drivers.
To add your own application, for one of the smaller examples, such as
stopwatch.c. Your app must provide functions for _init() (to run
at startup), _draw() (to run every quarter-second for rendering),
and _exit() which should just return 0 unless you need to intercept
the Mode button, in which case it may return 1 to delay the exit. Add
these three functions to a line of the apps[] structure in
applist.h.
In general, we try not to over-abstract the hardware because we don't
intend the design to be portable away from the CC430. Include
<msp430.h> if you need to access the CC430's IO registers or
"api.h" for all the standard functions of the GoodWatch firmware.
