i am using arduino uno. the display i am using is the 2.4 inch, 320x240 dots arduino uno shield with st7789V driver. i have tried using then adafruit tft libraries but those dont support the st7789 driver (as far as i know) and i tried using the st7789/st7735 adafruit tft library but it seems in this library they use pins on the display like TFT\_DC, TFT\_CS but my shield doesnt have a TFT\_DC pin but instead has the LCD\_RST LCD\_CS LCD\_RS LCD\_WR LCD\_RD any tips on which library works for this display? ---

Search for ST7789 in Library Manager. I have tested with `GFX Library for Arduino`. TFT\_DC and LCD\_RS are the same. `Data/Command` and `Register Select` are synonyms. Check if your display can work with 5V data signals. Use level converters else. ---

i have made sure that my display works with 5V but i still get a white screen provided that i have arranged the DC pin with the RS pin on my display. i am using the Adafruit\_ST7789.h, is this the correct library? ---

I did not test with Adafruit\_ST7789. So I don't know. And I don't have the same (unknown) TFT. Provide a link, then someone who knows your display might answer. ---

[Arduino\_GFX](https://github.com/moononournation/Arduino_GFX) is shown as `GFX Library for Arduino` in Library manager. I recently started to try some of my TFTs with this library. But sorry, I did test with ST7735, but not with ST7789. Doesn't seem part of my collection. ---
