Simple demo that uses RNG to pick a random phrase from a word list. Inspired by diceware (http://world.std.com/~reinhold/diceware.html) for generating passphrases. You cycle through a few words and use them as suggestions for passphrase instead of throwing dice.
Dictionary is rather limited currently, due to memory constraints. Will work on getting a larger one in there.
Conviniently, all diceware passphrases seem to fit on the screen and although limited font is sometimes confusing, it is readable.
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.
