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.
which library were u using
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.
