Hi all,
I am a lvgl newbie, using v8.2. I have some questions about lighting up a 4-bit grayscale screen. I have searched a lot of posts about 4-bit screen drivers, but there are still some things I don’t understand:
- 1 How to how to configure and convert images into arrays with lvgl’s image convert
- 2 Based on 1, how should I configure LV_COLOR_DEPTH
- 3 In Application Managed VDB Option · Issue #300 · lvgl/lvgl · GitHub and Display interface — LVGL documentation, I noticed that set_px_cb calls lv_color_brightness to compare with 128. I want to know why it is 128.what its mean?
Thanks
