I want to use the ESP32 port (lv_port_esp32) as a component with an ESP-IDF installation.
I followed the documentation in https://github.com/littlevgl/lv_port_esp32#install-this-project-as-a-library-submodule-in-your-own-project, but I got some problems.
menuconfig, there are no options for LittlevGL to configure (there are just no menu entries for them im contradiction to the above link), and thus when compiling I get errors like:
#error “LittlevGL: LV_HOR_RES_MAX and LV_VER_RES_MAX must be greater than 0”
which seems to be caused because CONFIG_LVGL_DISPLAY_WIDTH is not defined in sdkconfig.
#define LV_HOR_RES_MAX (CONFIG_LVGL_DISPLAY_WIDTH)
Configuration files are available here but they are not used during menuconfig. The Kconfig.projbuild is for the other project is working without any issues.
$ find . -name “Kconfig*”
So, what am I missing here? Any hints on how to proceed?
