gatedClock 70:7c0743c28b11 7 gotchyas
gatedClock 70:7c0743c28b11 8 1. using pc.printf inside a ticker routine will freeze the routine.
gatedClock 71:4a5f256ecf7c 9 2. using queues (get, put) will not work within a ticker routine.
gatedClock 76:74c454c9d75b 10 3. Ticker has a bug. http://mbed.org/questions/1563/Mbed-Tickerfunction-hangs-system-from-re/
gatedClock 80:e3e1a2161435 11
gatedClock 80:e3e1a2161435 12 improvements
gatedClock 80:e3e1a2161435 13 countdown timer needs to be sync'd to start button press.
gatedClock 87:147e2b08fae6 14 this could not be done, use granularity setting instead.
