I started playing with LVGL since 9.1.0. At that moment I noticed that most compact pixel format supported was 16bit (565), which is acceptable for my project and device. It is just not the one I’d like to use, due to I prefer to work with 8bit PF (RGB 233, 332, 323 and my favorite 222 with just 64 colors but proper shades of gray).
So, when LVGL 9.2.0 released with support of indexed L8 I quickly upgraded to it and started trying to update display drivers to 8 bit pixel format. Due to I did not found any information about specific pixel coding in LVGL documentation I just tried most popular ones 233, 323 and 332. But colors on the screen looked wrong.
So, I have a question what 8 bit pixel format coding LVGL 9.2.0 is using??? Is it RGB at all, or just a grayscale?
