Need a working example for LVGL

1

Hello
In the Arduino IDE I’m able to compile the LVGL example.
But not in PlatformIO Does someone knows a github link what is working.
I use ESP-Wrover-Kit 4.1

I have an LVGL demo on a Lilygo S3 running

Most of the LVGL stuff had to be done via the platformio.ini file

[env:lilygo-t-display-s3]
platform = espressif32
board = lilygo-t-display-s3
framework = arduino
monitor_speed = 115200
monitor_rts = 0
monitor_dtr = 0
lib_deps =
    esphome/AsyncTCP-esphome@^1.2.2
    esphome/ESPAsyncWebServer-esphome@^2.1.0
    igorantolic/Ai Esp32 Rotary Encoder@^1.4
    bodmer/TFT_eSPI@^2.5.0
    lvgl/lvgl@^8.3.6

build_flags =
    -D LV_CONF_INCLUDE_SIMPLE
    -I src

    -D USER_SETUP_LOADED=1
    -D ST7789_DRIVER=1
    -D CGRAM_OFFSET=1
    -D TFT_RGB_ORDER=TFT_BGR 
    -D TFT_INVERSION_ON=1
    -D TFT_PARALLEL_8_BIT=1
    -D TFT_WIDTH=170
    -D TFT_HEIGHT=320
    -D TFT_DC=7
    -D TFT_RST=5
    -D TFT_WR=8
    -D TFT_RD=9
    -D TFT_D0=39
    -D TFT_D1=40
    -D TFT_D2=41
    -D TFT_D3=42
    -D TFT_D4=45
    -D TFT_D5=46
    -D TFT_D6=47
    -D TFT_D7=48
    -D TFT_BL=38
    -D TFT_BACKLIGHT_ON=HIGH
    -D LOAD_GLCD=1
    -D LOAD_FONT2=1
    -D LOAD_FONT4=1
    -D LOAD_FONT6=1
    -D LOAD_FONT7=1
    -D LOAD_FONT8=1
    -D LOAD_GFXFF=1
    -D SMOOTH_FONT=1

with the build flags -D LV_CONF_INCLUDE_SIMPLE and -I src you can switch LVGL in an mode where you can configure the parameters outside the normal lvgl_config.h file.Just drop the file into the src directory. The rest of the flags was needed for eTFT_SPI, if I’m not mistaken.
