DIY esp32 ili9341 xpt2046

[straga]

Just for information. May some one need just esp32 and pure python Dispay/SPI driver.

copy *.py to board.

• lcd_bus (init.py, _basebus.py, _spibus.py) from mpdisplay
• busdisplay.py from mpdisplay
• ili9341.py from mpdisplay
• lv_mpdisplay.py from mpdisplay
• lv_utils.py from from micropython lvgl
• xpt2046.py from mpdisplay
• board_config.py from mpdisplay-diy_esp32_ili9341_xpt2046
• lv_config.py from mpdisplay

Now I am tested with master micropythin and esp-idf v5.2 work with out problem.

• change STATIC to static
• disable C esp32 sbus
• heap_caps and use python spi_bus for test, now work without.

Try by self for buidl: for testing.

• micropythonv and esp-idf
• mpy_cross and micropython configure as standart build and esp-idf

Micropython board for lvgl

sdkconfig.base

CONFIG_FREERTOS_INTERRUPT_BACKTRACE=n
CONFIG_FREERTOS_IDLE_TASK_STACKSIZE=4096

manifest.py

Not add yey, copy later direct to board

mpconfigport.h

define MICROPY_PY_MACHINE_I2S (0) probably not need with ned i2s driver.
submodules
cd to dir lvgl_micropython:
    git submodule update --init lib/pycparser
    git submodule update --init lib/lvgl
heap_caps if needed

in ext_mod rename to heap_caps

   add to ext_mod/micropython.cmake
      include(${CMAKE_CURRENT_LIST_DIR}/heap_caps/micropython.cmake)

build create

lvgl_micropython/build -> crate file lvgl_header.h

  #include "{Absolute path from root}/lvgl_micropython/lib/lvgl/lvgl.h"
  #include "{Absolute path from root}/lvgl_micropython/lib/lvgl/src/lvgl_private.h"

Build from standart micropython.
