lv_disp_drv_t struct

Horizontal resolution.

Vertical resolution.

Horizontal resolution of the full / physical display. Set to -1 for fullscreen mode.

Vertical resolution of the full / physical display. Set to -1 for fullscreen mode.

Horizontal offset from the full / physical display. Set to 0 for fullscreen mode.

Vertical offset from the full / physical display. Set to 0 for fullscreen mode.

Pointer to a buffer initialized with `lv_disp_draw_buf_init()`. LVGL will use this buffer(s) to draw the screens contents.

1: Use screen-sized buffers and draw to absolute coordinates.

1: Always make the whole screen redrawn.

1: use software rotation (slower).

1: anti-aliasing is enabled on this display.

1: turn the display by 90 degree. @warning Does not update coordinates for you!.

Handle if the screen doesn't have a solid (opa == LV_OPA_COVER) background. Use only if required because it's slower.

DPI (dot per inch) of the display. Default value is `LV_DPI_DEF`. MANDATORY: Write the internal buffer (draw_buf) to the display. 'lv_disp_flush_ready()' has to be called when finished.

OPTIONAL: Extend the invalidated areas to match with the display drivers requirements E.g. round `y` to, 8, 16 ..) on a monochrome display.

OPTIONAL: Set a pixel in a buffer according to the special requirements of the display Can be used for color format not supported in LittelvGL. E.g. 2 bit -> 4 gray scales.

OPTIONAL: Called after every refresh cycle to tell the rendering and flushing time + the number of flushed pixels.

OPTIONAL: Called periodically while lvgl waits for operation to be completed. For example flushing or GPU User can execute very simple tasks here or yield the task.

OPTIONAL: Called when lvgl needs any CPU cache that affects rendering to be cleaned.

OPTIONAL: called when driver parameters are updated.

OPTIONAL: called when start rendering.

On CHROMA_KEYED images this color will be transparent. `LV_COLOR_CHROMA_KEY` by default. (lv_conf.h).

Custom display driver user data.
