LILYGO T-HMI ESP32-S3 2.8 inch ST7789 on ESPHome?

ESPHome
1

I have bought this display: TDisplay S3 T-HMI – LILYGO®
Can anyone tell me if it’s supported by ESPHome at this stage?
The supplied examples in the GitHub - Xinyuan-LilyGO/T-Display-S3 repo is so complex I can’t even figure out what the mosi and clk pins are.

Many thanks for any help!

Looks like it’s an i80 bus to the st7789, not SPI. So not supported in ESPHome right now, but there is an external component that should work with it. Try this yaml - not tested but it should be a good start.

  name: t-hmi
  platformio_options:
    board_build.flash_mode: dio

unfortunately it doesn’t work
