[sdiy] Fast lcd display like digitakt

[Benjamin Tremblay]

What a difference a driver can make. 
I switched to the Arduino-GFX library (from Adafruit) and now rendering is so fast that I must slow it down. 
If the drawing is simple enough I do not need a canvas because everything is updated within refresh rate.

I am hopeful that I can draw a “page” of virtual knobs with values and labels and be able to switch pages efficiently.

I learned a lot trying to implement the Alesis Micron nrpn set. There are so many parameters that only a Teensy had enough ram to handle the C++ objects I created;
I went back to using structs and procedural code.  (I ported this from a Kaluma.js project I was doing for the Micron and it was all OOP. It ran of of memory, too. So I went back to the JavaScript project and also did away with OOP, referenced a single JS object for all the state, and it works better, too. Main problem is there’s no RAM left over for a display in the Kaluma project.) Thought for the day: JavaScript web programmers are lazy pigs who think nothing of having tens of megabytes to draw a sorted drop-down list.

Now I need to figure out how I want to show which page I am on and make it easy to navigate.
