I cannot make 7 pinned (without CS pin) ST7789 tft display work with rp pico 2

Well I tried bunch of different ways but only backlight worked all the time. I tried SPI0, SPI1. I tried different pins. I tried micropython, C/C++ (I don't know anything about coding I used AI). I tested connectivity with multimeter. Nothing seems to work with pico 2 but I managed to make it work with arduino nano so problem isn't the display.

Edit: I figured out the problem was data voltages.
