2004/12864 reprap LCD display not working with robin nano v3
i am trying to use reprap discount smart controller LCD 2004 and 12864 version with MKS robin Nano V3.1 board. i have tested the board using MKS TS35 and the display works fine. the 2004 and 12864 LCD display are also working when used with an arduino and RAMPS 1.6 Board. i have also tried to invert the EXP1 and EXP2 connectors, and also placed them upside down. when placed upside down. the display lights up but no text is displayed. i have tried multiple firmware uploads by enabling the displays, but it does not work. am i missing to enable any option in marlin?
Hi! I'm with a similar problem. I'm trying to use a LCD 12864 from anet with MKS robin Nano V3 board and it doesn't work it just turns on with a blank screen and the beep seems to work too.... I know the LCD is not broken because it works on a BTT skr 1.4 that I have.
Looking at the board pinout and LCD pinout they seem different to me, but I don't have enough knowledge to further solve this...
@crazyblaze here's probable solution. MKS lcd pins are rotated to 180 degrees, so if you are using anet LCD you should rotate it and plug. here's the example: https://www.youtube.com/watch?v=k2Ms2Cl5JFQ
and all the numbers match now!

Hi thank you! But I already did that and it didn't work =`(
I have found a solution to this problem.
Use
// // ULTIPANEL as seen on Thingiverse. // #define ULTIPANEL
instead of
//#define REPRAP_DISCOUNT_SMART_CONTROLLER
