It will be most useful to have the ability to reverse I/O direction. I am working on a traffic light model project with a group of KS2 children. Using 3 LED’s and a Buzzer consumes the 4 output lines.
Incorporation of a switch for input – (Like a pelican crossing cross request) only works once as Crumble needs power down to restore input sensing.
Hopefully I/O direction control code will be incorporated in software update revisions soon?
Or is there another way?
