Subject: [PATCH 6/6] Add SDL2 example support
|
|
|
|
Extend the main.c to support both legacy fbdev, DRM/KMS, SDL2 initialization.
|
|
The SDL2 window resolution can be configured using environment variables
|
|
LV_VIDEO_WIDTH and LV_VIDEO_HEIGHT and defaults to 800 x 480 .
|
|
|
|
To use legacy fbdev support, adjust lv_conf.h as follows:
|
|
LV_USE_LINUX_FBDEV=1
|
|
LV_USE_LINUX_DRM=0
|
|
LV_USE_SDL=0
|
|
|
|
To use DRM/KMS support, adjust lv_conf.h as follows:
|
|
LV_USE_LINUX_FBDEV=0
|
|
LV_USE_LINUX_DRM=1
|
|
LV_USE_SDL=0
|
|
|
|
To use SDL2 support, adjust lv_conf.h as follows:
|
|
LV_USE_LINUX_FBDEV=0
|
|
LV_USE_LINUX_DRM=0
|
|
LV_USE_SDL=1
|
|
|
|
Upstream-Status: Submitted [https://github.com/lvgl/lv_port_linux_frame_buffer/pull/47]
