Ender-3 / CR-10 LCD Display Connector pinout

The Creality printers are so popular that it is important to support its display controller. Finding pin mappings on the Internet was impossible (They merged 2x 10-pin to 1x 10-pin)

Here is the secret undiscovered PIN layout of their connector (The button pins might need a swap)

5V        GND
SID       ?
SCLK      Btn_En1
CS        Btn_En2
Click     Beeper

Here is my Klipper config for the BigTreeTech SKR 1.3 control board.
