tornado/fw/tornado.c: experimental code to log ADC samples to memory card
...
For a yet unknown reason, writing to the card fails if also processing
the samples. Maybe it's some side-effect of switching the LEDs.

tornado/fw/tornado.c: add test mode indicating positive zero-crossing
...
Works sometimes but often produces false zero-crossings, particularly
if there are many chain "jumps".

tornado/fw/tornado.c: use LED_* to communicate with LED bar; update demo
...
Instead of a counter, which worked okay with 16 LEDs but is useless with
all 64 of them, we now show a filling/emptying bar. The update speed is
high enough that rotation results in about a quarter-circle pattern.
