Wrong Display Dimensions for ST7789

[Coolie1101]

The problem

Trying to use a ST7789 (240x320) display configured as ST7789V, but the display view size is being rendered as 135 x 240 pixels instead of 240 x 320 pixels.

Example YAML snippet

spi:
  clk_pin: GPIO18
  mosi_pin: GPIO19

display:
  - platform: st7789v
    rotation: 180
    backlight_pin: GPIO4
    cs_pin: GPIO5
    dc_pin: GPIO16
    reset_pin: GPIO23
    id: display1
    pages:
      - id: page0
        lambda: |-
          it.rectangle(0,  0, it.get_width(), it.get_height(), id(my_red));
          it.print(0, 0, id(font1), "Hello World!");

Anything in the logs that might be useful for us?

hello @Coolie1101

i try few month ago to make it works with a 1.5" TFT with st7789v driver but its a lost of time ! (for me because my skill to rewrite the ST7789 Arduino library is bad lol) . the 135 x 240 pixels are hardcoded in the esphome library...only work with a TTGO T-Display module as shown in the beginning config page : https://www.esphome.io/components/display/st7789v.html?highlight=st7789

i use instead the st7735 esphome display...work nice...with a st7735 driver display of course... https://www.esphome.io/components/display/st7735.html?highlight=st7735

and my favorite is the ILI9341 : cheap, big (3.2" max) 320x240 pixels!

and a beautiful one is the SSD1351 https://www.esphome.io/components/display/ssd1351.html is a OLED display so very nice to display pictures but only 128x128 pixels...small

so..if you want to make it work with your display you have to make a custom_component st7789 in esphome folder in /config/ of ha and a lot of rewrite the arduino library st7789...

good luck!

@Electronlibre2012 Thanks for the info.

(for me because my skill to rewrite the ST7789 Arduino library is bad lol)

I'm even worst 🤣

and my favorite is the ILI9341

I did get this ILI9341, but it was too difficult to setup, as I think it wasn't the SPI version, I am going to try again with this SPI version, so many variables to be aware about, and not knowing what to look for has been a real challenge.

so..if you want to make it work with your display you have to make a custom_component

Too far fetch for me, I'll stick with the basics for now unless someone shares a config I can use.

I wish there was a simple flip option, as I have the ST7789 configured and working as a ILI9341, but the display is reverse.

Red and Blue is swapped, and text is mirrored (reverse), but I am able to utilize the entire display. Disregard the vertical line, it's from the screen protector.
