you could raise an issue in the u8g2 issue tracker.
A more detailed discussion of some controllers is listed in "controller_cmds.txt"
Q: What is wrong with connecting Reset (RES) of my display with the Reset of my
Arduino Board?
A:
- Both are inputs. It does not make sense to connect two inputs
- Both pins have completly different functions: The reset of your input will reset
the Arduino board, the reset of the display will reset the display.
Please connect the reset input of the display with a normal GPIO pin of your board.
Q: Shell I connect CS (chip select) with the SS output of the Arduino board?
AIn general this is required neither for hardware or software SPI.
Q: My board has a MOSI and a SCK output. Do i need to connect this to the
clock and data pins of my display?
A: "Yes" if you want to use hardware SPI (u8g2 constructors ending in _HW_SPI).
You can use any pins with the software emulated SPI of u8g2 (constructors ending
in _SW_SPI). Howver in general it is better to use hardware SPI to get a better
performance of your display.
