/* 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. */
