When will the lvgl component be added to ESP-IDF git? (IDFGH-10394)

[strawberry3papa]

Is your feature request related to a problem?

It is inconvenient to patch each time. When will the lvgl component be added to ESP-IDF git?

Describe the solution you'd like.

Please add the lvgl component to ESP-IDF git.

Describe alternatives you've considered.

We won't add LVGL into esp-idf repo, but LVGL has been in our component registry for a long time: https://components.espressif.com/components/lvgl/lvgl

For how to use it, please refer to esp-idf examples, there're many. e.g. https://github.com/espressif/esp-idf/blob/master/examples/peripherals/lcd/spi_lcd_touch/main/idf_component.yml#L3

Before that, you may want to read the document about how to use the Espressif component manager: https://docs.espressif.com/projects/idf-component-manager/en/latest/reference/manifest_file.html

It is inconvenient to patch each time.

Can you describe what is being patched in your project? The device driver or the LVGL porting layer?

thank yout about your help. I need to do the patch below after cloning the esp-idf git.

$ git clone https://github.com/espressif/esp-dev-kits $ cd esp-dev-kits $ git submodule update --init --recursive $ cd esp-idf $ git apply --whitespace=fix ../esp-dev-kits/esp32-s3-lcd-ev-board/factory/patch/release5.0_psram_octal_120m.patch $ git status # Check whether the operation is successful, the output should look like below

Perhaps if I do the example below, lvgl is automatically received? https://github.com/espressif/esp-idf/blob/master/examples/peripherals/lcd/spi_lcd_touch/main/idf_component.yml#L3

The patch you posted actually is not for the LVGL library, but for the PSRAM support. A 120M DDR psram feature is not available on esp-idf v5.0. To make it work, user has to applied the patch.

Since esp-idf 5.1, the patch is not necessary, because we're adding it as an experimental feature in the esp-idf. See https://github.com/espressif/esp-idf/commit/739b3f03fbada583fe6a07ca771754505ef5b3fd

I used esp-idf v5.1

An error occurred as below.

The following Kconfig combination work for me:

CONFIG_IDF_TARGET="esp32s3"
CONFIG_ESPTOOLPY_FLASHFREQ_120M=y
CONFIG_SPIRAM=y
CONFIG_SPIRAM_MODE_OCT=y
CONFIG_SPIRAM_FETCH_INSTRUCTIONS=y
CONFIG_SPIRAM_RODATA=y
CONFIG_SPIRAM_SPEED_120M=y
CONFIG_LV_MEM_CUSTOM=y
CONFIG_LV_MEMCPY_MEMSET_STD=y
CONFIG_LV_USE_PERF_MONITOR=y
CONFIG_IDF_EXPERIMENTAL_FEATURES=y

BTW, I'm testing on the master branch.
