Vex LCD module with Arduino

Hello, I am trying to program the old Vex lcd module with a arduino pro micro. I only found 1 source for this and it was with a uno. Would anyone know how to do this with a micro, I tried connecting it like the uno but all it ever shows is the “but 0 0 0” which I assume is for checking if the buttons work, I dont need the buttons. Any help appreciated.
