can not build initial lvgl without any code on esp32. I am getting error :
In summary it is lvgl library downloaded from GIT in /component folder can not access the headers on the main esp-idf.
I have of includes not found like driver/spi_master.h
All in esp32_drivers module
#include <driver/spi_master.h> is one cause driver folder and spi_master does not exist cause the component can not include header of the main esp32 componenet folder. The same issue doesn’t exist in main.c where the same include does not give issue.
unknown type name ‘lv_disp_drv_t’
unknown type name ‘lv_disp_drv_t’; did you mean ‘lv_fs_drv_t’?
What MCU/Processor/Board and compiler are you using?
I had also to change in code for one ili9341 the portTick_RATE_MS to portTick_PERIOD_MS though i know that the first defined is equal to the other. Irrelevant if i had freertos as required.
The next or last issue that i do not know how to fix is that gpio function that is not identified though driver/gpio.h is included without problem in file.
/components/lvgl_esp32_drivers/lvgl_tft/ili9341.c:84:5: error: implicit declaration of function 'gpio_pad_select_gpio'; did you mean 'esp_rom_gpio_pad_select_gpio'? [-Werror=implicit-function-declaration]
