GPIO or I2C
 
Hi,

The board i'm working has a I2C slave that has watchdog timer.

This watchdog timer can be reset either using a I2C command or by toggling a Processor's GPIO pin.


Which method should i use and why?

What is the speed difference?

I2C speed is 100kb/s.
GPIO samples at 111MHz.

Thanks in advance.

GPIO should be faster(intuitively). What kind of research have you done until now?
