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 | 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. |
