I was using this module:
https://www.amazon.com/gp/product/B09QG49MG8?smid=A50C560NZEBBE&psc=1
I’m not too sure how to draw something on it, the raspberry PI code doesn’t work but I tried using sudo ldto enable spicc-st7789v-240x240
But I’m unsure where to go now or if my pin setup is even correct. Does anyone have anything to help with this direction?

Besides the normal SPI pins, the other pins are defined above. You need to match it to the proper GPIOs . The framebuffer should then be exposed as /dev/fb0 or /dev/fb1 depending on if you have HDMI connected.
Ignore any Raspberry Pi instructions. Do not follow any of them or try to run any instructions/commands from those tutorials.
Also see:
It seems to be working with the new overlay you guys put up “spicc-st7789v-240x320-legacy.dts”, but here is the picture of the front and back of the display in case you mean something more specific that I am missing. Thank you!
