Hello,
I am curious if there is some "standardization" for using GPIO pins.
I mean, what GPIO is used/recommended/preferred for various signals like 1wire, seatalk, shutdown and so on
I am trying to develop some kind of hat and I want to do that without conflicting with other hats, like MacArthur.
By example, MacArthur hat is using GPIO20 for seatalk_rx, GPIO21 for shutdown, GPIO26 for power_off and GPIO19 for 1wire.
Other "serious" hardware devices are sticking on same pins?
Also, maybe we can try to do a list with the most used signals and their GPIOs pins. I hope will be useful for hardware design.
Fair wind,
Seb
