Hi. Just got my DigiX. In the "Tools -> Board" menu, There's *two* DigiX options - which one have I got? "standard" or "WDT"? (WTF is WDT?) How can I tell?
In the instructions, I'm told I can also choose Due... but Due also has 2 options: "Programming Port" or "Native USB Port" - which one am I supposed to pick?
Please do not answer me here. Please fix your instructions, and provide me with a link to the fixed instructions page. (Every new user you've got will be suffering the same confusion - better you fix the problem, than appease just me only)

The wiki actually says to use the Native Port when using the board as a Due: http://digistump.com/wiki/digix/tutorials/basics
When using the DigiX setting, I use the Standard mode and it works fine. But I admit I wonder as well what WDT is and what it is for, and I saw no mention of it anywhere.

All about WDT can be found in chapter 17 of the SAM3x8e.
With the WDT option, the watchdog timer is enabled, which is in the standard DUE configuration disabled.

The watchdog timer allows (among other things) for you to reset the board if it becomes unresponsive (say in a long term installation) and also to put the board to sleep and wake it up periodically - it is an advanced use that most will never need, which is why we call the default setup standard. If you use that option your board will reset every 8 seconds (I think without looking it up) - unless you add a command to kick the wdt

Hello trying to activate WDT but my IDE in the "Tools -> Board" menu, There's no "WDT" variant.
How can I enable it?
Do I have to change the hardware\digistump\sam\variants\digix\variant.cpp file?
change what?
In another post it is suggested to switch the file with variant_wdt.cpp There is no such file in the latest DigistumpIDE1.5.8C I use.
Help please?
