Errors building LVGL micropython for esp32-s3, but esp32 works

Micropython

OK so here goes.

put the attached file into micropython/lib/lv_bindings/driver/esp32

edit micropython/lib/lv_bindings/mkrules.cmake

at the very bottom change

if(ESP_PLATFORM)
    LIST(APPEND LV_SRC
        ${LV_BINDINGS_DIR}/driver/esp32/espidf.c
        ${LV_BINDINGS_DIR}/driver/esp32/modrtch.c
        ${LV_BINDINGS_DIR}/driver/esp32/sh2lib.c
        ${LV_ESPIDF}
    )
endif(ESP_PLATFORM)

to

if(ESP_PLATFORM)
    LIST(APPEND LV_SRC
        ${LV_BINDINGS_DIR}/driver/esp32/espidf.c
        ${LV_BINDINGS_DIR}/driver/esp32/modrtch.c
        ${LV_BINDINGS_DIR}/driver/esp32/sh2lib.c
        ${LV_BINDINGS_DIR}/driver/esp32/makerfabs.c
        ${LV_ESPIDF}
    )
endif(ESP_PLATFORM)

then edit micropython/ports/esp32/main/CMakeLists.txt

in the middle of the file around line 106ish you will see

set(IDF_COMPONENTS
    app_update

change that to

set(IDF_COMPONENTS
    esp_lcd
    app_update

compile it and load it onto your ESP

Python code

from makerfabs import makerfabs

display = makerfabs(
    de=40, vsync=41, hsync=39, pclk=42, 
    d0=45, d1=48, d2=47, d3=21, d4=14, d5=5, d6=6, d7=7, 
    d8=15, d9=16, d10=4, d11=8, d12=3, d13=46, d14=9, d15=1, 
    width=800, height=480, 
    hsync_polarity=0, hsync_front_porch=8, hsync_pulse_width=4, 
    hsync_back_porch=8, vsync_polarity=0, vsync_front_porch=8, 
    vsync_pulse_width=4, vsync_back_porch=8, pclk_active_neg=1, 
    speed=16000000
)

You have to add the code for handling the back light for the display. simple GPIO and turn it on.

And that should do it. This is not going to do the touch. I am going to work on that in a little bit. That will be written in Python.

I am not sure if LVGL is going to play nice nice with using the buffer that is made by espidf. we will soon find out. I manually called the draw function in the flush instead of dropping the buffer into a queue to be written. This is because of using a shared buffer
