Hi all!
I need additional ports for neopixel and UPS. I tried to find pinout in marlin (in pins_BTT_SKR_PRO_common.h) for extension-1 and extension-2 (I/O expansion ports) but there is no info. On the board pinout diagram I see for example PE4 pin. Is it possible to use it in marlin or not? If not what other solution can I have in this case? All my limit pins are in use (X, Y, Z1, Z2 limits and two filament runout sensors). Thanks in advice!
