I'm looking at implementing the watchdog timer in the Netduino 2. What would be the best way to do that? I need it to time out after some time and pull the MCU reset line.

Hello,
I think in the moment it's not possible to use the internal watchdog, so you have to use an external one.

So it is not possible to access the MCU registers and configure the internal watchdog as part of my application? I'm new to .NET programming but that seems like a waste of resources as well as an extra cost for the external watchdog hardware.

That is maybe a feature for the next firmware releases ...
The Hardware is just one little chip, e.g. MAX6371, and a resistor. Not more than 3 EUR and 100% reliable.

I have been doing embedded HW and SW systems for over 25 years. This is my first C# project. Having done wdogs in every product in C, I must say that I'm not overly impressed by C# (maybe it would be different if I truly knew C# the way I know C). Anyway, back to the problem.
Can anyone from Secret Labs comment on the possibility of implementing the internal watchdog timers in a future release?
