A20M Gt2560 V3 pinout NEEDED

[3DAngel]

hello to Geetech...

could I have the pin out for the A20M on GT2560 V3?

the pdf sch at your site vs the WORKING Marlin 1.1.8 pin_GT2560_v3.h do not match.

need the updated pin out specific to the A20M....LCD

CS_Pin
A0_pin
etc...

Much appreciated
Thanks

Hi, Can you provide your specific picture?
Or point out your disagreement?

[3DAngel]

here are some of pins... but it is more than what I just marked..
would someone from Geeetech revise the GT2560 V3 for A20M sch.pdf?

pins identification from Geetech's github Marlin for A20M.

it would made thing easier and not that confusing...
thanks

Basically need to find out how to get the LCD to work with KLIPPER

[display]
lcd_type: st7920

sclk_pin:
sid_pin:

thanks in advance

so the pin out is not as described on the schematic.

the pin # are referring to the pin out of the Arduino MEGA board.
received help from Geetech and figured the needed pin out and got the LCD to work on Klipper FW.
cheers
