My conclusion is, until proven otherwise, that ESP-IDF v5.2.1, LVGL 9.2.0 and LVGL_ESP32_DRIVERS is not compatible. Somewhere between ESP-IDF v4, LVGL 8 and now, things got broken, and nobody picked up the problem.

Whats the alternative? I have a nice ST7789 that i would like to get up running.

No, I am still strugling. I do not understand, why all documentation states, that ST7789 and LVGL should go together easily with ESP32, when it is so difficult to get to work. No online examples work, most of them will not even compile, the documentation is incomplete. It seems like a mess of new li...

Or is the driver actually included in the lvgl 9.1? I just can not get it to compile....

Hi kyrpav. I have tried your aproach multiple times, cause I have the exact same errors, with same missing components and unknown types. However, following your fixes doesnt change anything. I use platformio esp-idf 5.2.1, latest lgvl_esp32_driver and a checkedout version of lgvl to version 8.3.0. D...

Hi there. Recently I moved from arduino to Espressif framework within Platformio. Bigger difference, than I thought, and I am still learning. Now I am going to use my first color display (ST7789 driver), and wonder what way to go. LVGL seems to be the way. I just need a driver for the Espressif plat...

Hi forum. The compile errors are these In file included from components/lvgl_esp32_drivers/lvgl_tft/../lvgl_helpers.h:18, from components/lvgl_esp32_drivers/lvgl_tft/st7789.h:20, from src/main.c:8: components/lvgl_esp32_drivers/lvgl_tft/../lvgl_tft/disp_driver.h:75:24: error: unknown type name 'lv_d...

Hi Forum. I am not able to compile when I install latest lvgl and lvgl_esp32_drivers. Is there a problem with the newest lvgl and the current drivers? I get a bunch of "unknown type name" upon compiling, even without any real code. Should I try and use an older version og lvgl, or is there a better ...

I simply can not get this to work, tried several aproaches.
Is this custom outbox implementation working in IDF 5.2.1?

If anyone have a working implementation, I would really like to see it. Any input would be apreciated, I am stuck....

Br. Frank.

I run 40K samples without any problems. Are your buffers big enough?

Here is my aproach. What am I doing wrong? Initially I get undefined reference to `outbox_set_pending' Then I add this CMakeList.txt idf_component_register(SRCS "main.cpp" "outbox.cpp" INCLUDE_DIRS "." REQUIRES driver freertos u8g2 PRIV_REQUIRES esp-mqtt) and then I get Failed to resolve component '...
