Compilation errors in esp_helpers.c

[tigerya214]

I have two problem about compile the esp_helpers.c, 1、I think it is not support the esp32-s3, because I find there are not esp32-s3 in line 200 to / Initialize spi bus master / 2、what compiler should I choose? (I am not using the windows-msvc-x64)

Anything about this error?

ESP32 and ESP32-S3 have different SPI names for setup. HSPI and VSPI is for ESP32. Aside from that, in my experience there are several compatibility issues with current lvgl and lvgl_esp32_drivers because the drivers haven't received support in a while. But this post has helped me: https://www.esp32.com/viewtopic.php?f=40&t=32455&p=110662#p110662 Or use lvgl 7.11

Thanks @paranormal-programmer to walk me into the right path. I manage to make the build successfully up to the latest version of LVGL. I have another question, as I'm trying to use the drivers on lv_micripython as modules so they shoud be build as mpy for my board, I need to generate bindings using gen_mpy.py or any other tool if available. I have try for the last two weeks, trying everything on my mind. even asking chatgpt. But i haven't manage to do it. This Probably its not the mean to ask, but any help in this, would be appreciated. Thanks in advance.
