Hi Darrel,
I have several displays that support either parallel or SPI interfacing.
Since I currently use this display (see picture) in 4/8 bits mode (datasheet is here http://www.lcd-module.de/eng/pdf/doma/dog-me.pdf), I think I get the best chance to learn how to get it to work via SPI.
But let's stick on basics, please.
What is SPI all about? What do I need to know to use SPI? What are the minimum requirements to make it work? So many questions....
