hi everyone,
i'm trying to activate an LCD on NanoPi Neo Core.
I want to use it as a display for a wizard for connecting to a wifi network using touchscreen.
i tried using this command (which did created a fb1 device) but the screen isn't showing anything:
sudo modprobe fbtft_device custom name=fb_ili9486 gpios=reset:7,dc:8 speed=16000000 fps=30 rotate=90
i have tested with an oscilloscope and dc pin don't have any output.
this is the lcd im trying to connect (it's designed for arduino but i figured an SPI should work also on NanoPi).

can someone please assist me?
thank you.
