According to the comments on the Sparkfun page, [color=#008000;]I could solve the problem[/color]. Somebody recommended to write a tight loop (e.g. 100ms) to get the min and max values. The difference between the two will give us the volume (sound pressure) during that time.

I'm sure you can find a watchdog IC that is available in DIP8 - just stick it down the breadboard, connect 2 wires (plus power) and you're good.


Thanks for your information. I will try to buy one. Since I am not expert, is there any specific name/ID for the IC your mentioned?

In Topic: Software Reboot for Netduino Plus

Thanks Khmesmer.

I am working with Netduino Plus (or generally microcontroller programming) since 2012. I recommend you to follow the "getting started with the nternet of Things" book, first. Then, try to implement codes and ask your questions in this forum. To be honest, this forum and its members :) helped me a lot in my projects and learning.

If you have any questions, feel free to let me know.


Good Luck

The code you attached before would restart the device repeatedly between 10:00 and 11:00 AM, effectively rendering it unusable during that time. Am I right?


Yes, you are right :), but by using the Timer class, you can implement it more effectively.


Personally, I think there's no such thing as a software watchdog. You can't write software to check if another piece of software has locked up. If I remember correctly it's one of those NP complete problems within the theories of complexity. :)

I partially agree with you ;), you know in multi-threading world, sometimes one thread blocks all its processes (e.g., this problem), and the problem is solved by a simple reboot. At this time, one thread can be in charge of software reboot, and the other threads are doing their tasks. If any fail or error situation occurs, the reboot thread can perform its task :)

In Topic: Hardware watchdog on Netduino Plus

That's not a watchdog, it's a scheduled reboot.

 You are right, so I should not consider them interchangeably.


have you tried out my firmware build?

No, since the firmware of your library was different from mine.



What are the problems you mention in the other thread ('I had a problem for 1 month to use a Watchdog mechanism in Netduino Plus') ?

The watchdog problem :) to reboot the Netduino Plus after a specific time.
