For instance, x, x, x, x, etc. Support for 16, 18, bits per pixel RGB in hardware frame buffer. Can operate directly on internal video buffer in the display controller chip. No needs for a graphic video buffer in processor RAM.

David, Yesterday I did all of the things you suggest. Remove any multiple libraries. Install from ZIP. Then I installed it from. I reported multiple libraries again. When it ran, it said that it took ms to start, and said the ID was 0x0. Delete the unwanted version. Did all of that. I am running the test code library. It does not use any library. I have to write a new hardware driver for every target wiring.
It uses the hardware port pins directly instead of by digitalWrite What is the nature of DIY and doing projects with a set of product that are designed for it? These devices have timing specs and the hardware and software should be able to meet them without a big problem. There should be a way to define the pins that the data and control lines are hooked up to, and tell the software what they are.
They use bit-banging rather than data bus reads and writes, so it should be pretty flexible. So what does your library use instead of digitalWrite?. Why not build the lowest level using DigitalWrite? That talks to the pins directly, no ports, etc. Seems it would be pretty easy to assign to different pins, etc. Ultimately I think the Arduino folks should have better way to describe what kinds of things should be done to write software so that it can run on multiple products without so much angst.
Different result compared to yesterday.
