Re: Watchdog
More generally, a "watchdog" is simply a timer that needs to be "serviced" every so often or the system activates some sort of fail-safe mechanisms. In the world of engineering, we often use watchdogs to monitor systems of several processors or devices - a pulse is periodically sent out to all devices, and if a response is not received in a given window of time, then the system assumes that the device that failed to respond has stopped working, and acts accordingly.
In FIRST, the master uP and user uP indeed have a watchdog-like relationship.
