Watchdog with OpenTracker

[varlux]

Hi everybody,

 I would like to use watchdog in my project, but first I need to understand.....

In Arduino core files (wachdog.ccp - watchdog.h) I find the functions that manage this feature ( watchdogEnable; watchdogDisable; watchdogReset; watchdogDefaultSetup )

but....

In variant.cpp I read (line 319):

// Disable watchdog
WDT_Disable(WDT);

So..... Is it possible to use watchdog? And how to?

Thanks

SAM3A/X family is different from ATmega. Once you disable the watchdog, you cannot re-enable it.
You may try to comment out that line from "variant.cpp" and add code to handle watchdog in your setup() and loop() functions.
Be aware that it will not be an easy task, because there are many places in OpenTracker code where we have have active waits inside a loop, which may potentially last much longer than the watchdog period.
