Both use Pi pin 7 (BCM 4). On the OLED Bonnet this is the momentary switch in the centre of the joystick and on the LiPo Shim it’s the Low Battery signal.
This isn’t a problem programmatically, since you can set the clean-shutdown daemon to require, say, a 5 second press to initiate shutdown. It’s useful, actually.
My question is: Is there an electrical problem using a pushbutton switch on the LiPo Shim’s Low Battery pin? Am I going to burn something out?
