Hi!
I'm doing a project that is really starved on GPIO, so I need to use GPIO16 for both deep sleep reset and for sensing if it's high or low based on a latching button.
I made this circuit based on random components and stuff I found on the internet, and it works if I replace the left 3.3v source with a 5v source, but I obviously don't want to do that, both for the capacitor's sake and the ESP's sake.
Can someone help me point out what I need to do to make this work? It's currently working for wakeup when the switch is pressed (and kept) down (GPIO16 low), but it's not registering a return to HIGH status if I release the button.
PS. I'd like to point out that I'm very new at this, making these circuits up as I go, and that I have no idea what values to use for resistors and such.

Ok, so my actual circuit had a bug. The drawing works!
However, could someone tell me if it's safe? I'm worried about overloading the RST-pin.

3.3V is safe, some say even 5V is safe.
