User has confirm this works

I've also tested on MKS_TINYBEE with FYSETC_MINI_12864_2_1

Don't merge yet, Documentation says is also supports LCD2004, 12864 screens, though code doesn't enable spi for the latter...
want to look into both of these.

Confirmed works on REPRAP_DISCOUNT_SMART_CONTROLLER and REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER but like all mks products exp1 and exp2 are rotated 180 degrees, so cables need to be rotated to work.

…like all mks products exp1 and exp2 are rotated 180 degrees…

So if I wanted to connect, say, the MKS_TS35_V2_0 to a BTT board, the cables would need to be rotated 180°? Or is that display's pins in the correct orientation? Also, I see this MKS display requires 3.3V on EXP2-01 which MKS boards provide, but other boards might not. With 3.3V on that pin, it should be adaptable to any board.

Yeah, I've got LCD unification on my mind lately. I might take a stab at making a RRDFGSC.h file that can be included by pins.h and see what ends up being required to make it doable.

Correct. All of MKS' EXP pins are 180 out compared to other boards/brands. MKS even made two videos about it here and here.
