Here we have the system task menu tab. This enables you to set the external watchdog timer - useful for remote
applications where you can't come and do a hard-reset yourself if the Pi crashes or hangs. The PiJuice essentially monitors
for a "heart beat" from the software - if it does not sense it after a defined period of time it automatically resets the
Raspberry Pi. You can also set here wakeup on charge levels, minimum battery levels and voltages.
The watchdog timer has a configurable time-out. It defines the time after which it will power cycle if it doesn't receive a
heartbeat signal. The time step is in minutes so the minimum time-out period is one minute and the maximum is 65535
minutes. The number can be any whole number between one and 65535. If you set the time to zero the watchdog timer will
be disabled.
System Events Menu
This is the system events menu tab. It allows you to trigger events for certain scenarios such as low charge, low voltage and
more. Each paramater has a couple of preset options to choose from, and also you can select options from the "user scripts"
tab which allows you to trigger your own custom scripts when certain system events occur for maximum flexibility.
