I must be missing something basic...
I am trying to test the Dual Watch Dog before attempting a connection to reset.
1) Power is connected to 3.3v pin on Nodemcu
2) And Gnd is connected to Gnd on NodeMcu.
3) My test app is in a 4 second loop, setting and reset a GPIO pin which is connected to watch dog input.
4) The DogOut pin is connected to an LED / resistor to +3.3v
I see the red LED on the watch dog going off and on with the input
And the output pin is going on/off with the input...
What am I missing...I though the output triggered with the absence of the input signal?
Thx,
