We are trying to connect Dual WatchDog Timer Board with a Beaglebone Black. We're newbies in IoT world and we have some questions and doubts about hardware and software. Is this connection schema correct? BBB P9_5 (VDD_5V) -> SDL VDD BBB P9_1 (GND) -> SDL GND BBB P8_14 (GPIO) -> SDL JP7 Dog1 Input BBB P9_10 (SYS_RESETN) -> SDL JP4 Arduino Reset Is enough, or is needed to connect Pin 1 and Pin 2 of GROVE connector to 3.3 V like says in forum.switchdoc.com/thread/283/documentation-model-connection-watch-dog ? Do you have any test code for Beaglebone like code we found in forum.switchdoc.com/thread/283/documentation-model-connection-watch-dog?In this code what is the meanig of RESET_WATCHDOG1 = 12 and READ_WATCHDOG = 6 or what are their equivalent for Beaglebone Black code? Thanks in advanced.

Depending on your revision of the WatchDog board, yes. Connect Pin 1 and 2 to 5V in your case, but 3.3V would not have heart anything.
No test code for the Beaglebone, but you should be able to translate our code easily enough.
n this code what is the meanig of RESET_WATCHDOG1 = 12 and READ_WATCHDOG = 6 or what are their equivalent for Beaglebone Black code?
Those are the pin GPIO pin numbers. Convert them to the GPIO numbers you are using on the beagle black.
Best,
BP
