// Even though the display controller protocol over the SPI bus is standard as per e.g. ILI9341 spec sheet,
// and the pins that one uses for the Pi hardware SPI are also standard;
// the choice of which Raspberry Pi GPIO pin is used for flipping the Data/Control pin of the display
// can vary. Pre-made stack-on hats such as on Adafruit's ILI9341, or predesigned schematics configurations
// such as Freeplaytech's WaveShare32B display wiring can standardize the pin to use in some configurations, but
// if you did your wiring customized directly on the GPIO pins, you will likely need to check which pin to
// configure here. This pin numberings is specified in the BCM pins namespace.
