12 A draw buffer can be initialized via a `lv_disp_draw_buf_t` variable like this:
27 As you can see above, the draw buffer may be smaller than the screen. In this case, larger areas ar…
46 This way, the rendering and refreshing of the display become parallel operations.
49 …the `full_refresh` bit will force LVGL to always redraw the whole screen. This works in both *one …
51 This means the `flush_cb` callback only has to update the address of the framebuffer (`color_p` par…
52 This configuration should be used if the MCU has an LCD controller peripheral and not with an exter…
56 It this case `flush_cb` will be called only once when all dirty areas are redrawn.
59 Therefore the 2 buffers needs to synchronized in `flush_cb` like this:
89 - `physical_hor_res` horizontal resolution of the full / physical display in pixels. Only set this …
90 - `physical_ver_res` vertical resolution of the full / physical display in pixels. Only set this wh…
91 - `offset_x` horizontal offset from the full / physical display in pixels. Only set this when _not_…
92 - `offset_y` vertical offset from the full / physical display in pixels. Only set this when _not_ u…
105 This way the buffers used in `lv_disp_draw_buf_t` can be smaller to hold only the required number o…

217 You can do this in the following way:
