NEC uPD7228 / uPD16434 LCD controllers

I have recently discovered the joys of using Arduinos, and have a pile of salvaged parts including stepper motors and LCD displays that I can finally easily use. Going through my LCD displays I found a couple of that looked useful, but don't have the common Hitachi HD44780 controllers, but old NEC uPD7228 chips instead. These have been superseded by the NEC uPD16434 chip. After a futile search for Arduino drivers, I have written my own, so that I can at least test them. So if anyone is looking for a functional, though not elegant, driver they are welcome to use my code which I have posted at arduino:uPD7228_driver_library [My Projects] .
