Unfortunately I can't get it to work...
When I connect the Watchdog input to one of the GPIO, without any code running, it never triggers...
I tried with Grove pins 1 and 2 up to VDD with and without a 100K resistor. No difference...
On a brand new Raspberry PI 3 Model B+, without any app for watchdog, led never blinks when connected to a Raspberry pin that has an internal pull-down resistor. If I connect to a pin that has an internal pull-up resistor, it triggers every 6 seconds or so.
1. I use Windows 10 IoT and behaves differently. More info here:
github.com/ms-iot/bsp/issues/44 . Do you think this could be an issue for the Watchdog?
2. I also tried to monitor the outpu and I've seen a high frequency of signals. Output below:
