Uno R4 WiFi Board Watchdog

Official Hardware UNO Family UNO R4 WiFi

Hello Arduino community,

I'm looking for assistance on how to enable the Watchdog Timer on my Arduino Uno R4 WiFi board. I'd like to provide information on what I've tried so far and if you have any suggestions or solutions, please share them.

What I've done so far:

  1. I attempted to enable the Watchdog Timer with a simple code uploaded to my board using the Arduino IDE, but it didn't work as expected.
  2. I tried some code snippets that are supposed to disable the Watchdog Timer, but I still couldn't get it to work.

I'm open to your suggestions. Is there someone who can provide the necessary code snippets and connections to properly run the Watchdog Timer?

Hardware and software versions I'm using:

  • Arduino Uno R4 WiFi board
  • Arduino IDE version 2.2.1

Thank you!

did you try the WDT library which is bundled with the core? It has examples

"Thank you for the suggestion, but I've already tried using the Watchdog Timer. However, I encountered two issues with it:

  1. The watchdog timer's control interval is too short for my application, and I need a longer duration before the timer resets the board.
  2. Once I activate the watchdog timer on one board, I find it challenging to disable it or turn off the watchdog functionality completely.

I'm looking for a solution that allows me to set a longer control interval for the watchdog timer and also find a way to deactivate it when needed. Any suggestions or alternative approaches for achieving this would be greatly appreciated."

Thank you next time I'll be more careful

Where does one find out what is "bundled with the core" ? We cannot find the documentation for the software? In general. We are not aware of where to look for documentation - we have been quite a lot around here - but we cannot find like one place for the documentation for the various boards.

Can you maybe help with a link or something like that?

just look at the source code
