I’m trying to do some custom work on my ender 3 Max. Specifically, what the pins are for the display and beeper. Can anyone offer some assistance?

[display]
lcd_type:st7920
cs_pin:PB12
sclk_pin:PB13
sid_pin:PB15
encoder_pins:^PB14, ^PB10
click_pin:^!PB2

[output_pin beeper]
pin=EXT1_1

I found a wiring diagram for the E2v2, but it has a different display so some of the pins are different.

 

Thanks
