Klipper Firmware LCD config

Does anyone have the appropriate LCD configuration section for setting up Klipper firmware on the A20M? Maybe an updated schematic for the GT2560v3 and LCD panel would also work.
thanks!

Someone else on this forum mentions that he got it working, but unfortunately didn't post how.
#[display]
#lcd_type: hd44780
#rs_pin: ar20
#e_pin: ar36
#d4_pin: ar21
#d5_pin: ar21
#d6_pin: ar5
#d7_pin: ar6
#encoder_pins: ^ar16, ^ar17
#click_pin: ^!ar19
Basically I need pin definitions for the GT2570v3 + LCD panel on the A20M to configure here.

This is resolved - for those searching on how to make Klipper work with the A20M LCD :
[display]
lcd_type: st7920
cs_pin: ar5
sclk_pin: ar21
sid_pin: ar36
encoder_pins: ^ar16,^ar17
click_pin: ^ar19
[output_pin beeper]
pin: ar18
The GT2560v3 schematic is useless, had to derive this from digging through the Marlin firmware.
