Hi Penelopepug,

The Noritake VFD displays work just like any LCD display. Search this forums posts for any programs using LCD's and there you go. I am using Noritake 4x20 displays following the PBP manual for 4 bit setup and also for 8 bit setup. There is a jumper option on the display to setup for 4 bit operation. You can get a manual on your display by going to Noritake's website and searching for the model number. It was real easy. Keep in mind that these VFD displays draw some awesome power compared to a regular LCD. Mine is pulling about 250ma and they do get warm!

Hope this helps you!
