Waking up a Deepsleeping ESP

I am using a STM32F10 (maple mini) in concert with an ESP8266.
THE maple mini is doing all the IO and the esp is sending logged data to thing speak and synchronising time etc.

TO save power I am putting the esp8266 into deepsleep,
at the moment it is running with the deepsleep function on the esp,
however does anyone know how I would wire the reset button etc?
the two chips have a common ground. I just don't want to fry something by accident.

You means STM32F103 ...
I would simply use a GPIO to the RESET pin, and driving the GPIO as output LOW only during the reset request, while turning this GPIO as input the rest of the time.
