Using local lv_conf.h with custom esp_bsp as a component (BSP-483)

[sukesh-ak]

Sample project
https://github.com/sukesh-ak/BSP-IDF5-ESP_LCD-LVGL9

Usually for lvgl to work with local custom lv_conf.h, I use the following in the CMakeLists.txt which is in the root.
This always worked but now with bsp in the components folder, this does not work anymore.

#LVGL custom config file setup
idf_build_set_property(COMPILE_OPTIONS "-DLV_LVGL_H_INCLUDE_SIMPLE=1" APPEND)
idf_build_set_property(COMPILE_OPTIONS "-I../main" APPEND)

Not working (default sdkconfig)

#
# LVGL configuration
#
CONFIG_LV_CONF_SKIP=y
# CONFIG_LV_CONF_MINIMAL is not set

Working

Note

If we uncheck Check this to not use custom lv_conf.h under Component config > LVGL configuration with idf.py menuconfig.

#
# LVGL configuration
#
# CONFIG_LV_CONF_SKIP is not set
# CONFIG_LV_CONF_MINIMAL is not set

So the question is, how to make the above work without the user going into idf.py menuconfig, just to uncheck the Check this to not use custom lv_conf.h ?

Hello @sukesh-ak ,
when you are using LVGL with Espressif chips, there is only menuconfig solution for LVGL configuration. For default settings is recommended to use sdkconfig.defaults.

It seems, that you have same question as we from Espressif. We are solving this here: lvgl/lvgl#6010
We want to set some default settings from component and not need for it sdkconfig.defaults in examples/demos.

@kisvegabor it seems, that it is same issue as here lvgl/lvgl#6010

Thanks for tagging me. I have a few items on my todo list, but after that we can prioritize lvgl/lvgl#6010
