FYI:
The simple-rover example uses an unsafe test value for touch sensors.
Touch sensor should be tested against <0xf000, NOT <0x2000
(e.g. simple-rover.c)
Reason: Not pressed has a constant value >0xf000.
Pressed varies depending on battery change, but <0xf000 seems
safe for pressed. (Notice that values above 0x2000 were
encountered before the battery low symbol appears on the LCD.)
