Piobu as gpio

Tue Oct 16, 2018 5:19 am

I can’t seem to find whether or not the piobu0-5 pins can be used as gpio, or at least inputs. All I have found is a piobu.h file which would seem to indicate so.

The device in question is the atsama5d225c with integrated ddr.

Another question, are there any 6800 or 8080 style lcd interface examples? I assume a person would need to use the ebi for this? My comparable experience would be using a pmp on the pic32 series.
