lvgl_helpers: Add comment about DISP_BUF_SIZE
2021-02-07 23:55:20 +00:00
/* DISP_BUF_SIZE value doesn't have an special meaning, but it's the size
* of the buffer(s) passed to LVGL as display buffers. The default values used
* were the values working for the contributor of the display controller.
*
* As LVGL supports partial display updates the DISP_BUF_SIZE doesn't
* necessarily need to be equal to the display size.
*
* When using RGB displays the display buffer size will also depends on the
* color format being used, for RGB565 each pixel needs 2 bytes.
* When using the mono theme, the display pixels can be represented in one bit,
* so the buffer size can be divided by 8, e.g. see SSD1306 display size. */
