[Discussion] Using I2C0 instead of I2C1 #26

Description

@rbolinger

Anyone know if this will work on the I2C0, pins 27 and 28, rather than I2C1, pins 3 and 5? I am trying to add a power button too and while I can splice the SCL from the OLED display into a momentary switch running a script to watch for pressing a button on GPIO3 (pin 5) kills the communication to the display. And yeah I could move the momentary switch to another GPIO but as far as I know the wake up pi only works when you short GPIO3 to a ground.

Right now I have it still connected to I2C1 and the momentary switch spliced, it allows me to wake the pi from a shutdown state but not shut it down from the button.
