The ARM Integrator AP and CP base boards I have here have 7-segment displays as well. But it's not on GPIO but dedicated registers, so I could implement these as, e.g. LEDs. But with this framework I'd just make a driver that pokes directly into the registers. However as Russell points out, this needs to be thought through. I have a period on my display between the two characters, so how do we model that period?
