@note This package needs the 32bit version of SDL2
|
|
|
|
|
|
|
|
|
|
@see https://github.com/lvgl/lv_drivers

## Configuration options
|
|
|
|
|
|
|
|
|
|
To change the size of the screen `SDL_HOR_RES` and `SDL_VER_RES` can be changed
|
|
|
|
|
via `CFLAGS` or in `lv_drv_conf.h`.
|
|
|
|
|
|
|
|
|
|
For small screen a zoom factor can be applied through `SDL_ZOOM`, e.g: `SDL_ZOOM=2`
|
|
|
|
|
will apply a x2 zoom to the display.
|

### SDL Requirements
|
|
|
|
|
|
|
|
|
|
To run lvgl inside a simulator (native), SDL2 is required. Install instructions
|
|
|
|
|
can be found at https://docs.lvgl.io/latest/en/html/get-started/pc-simulator.html#install-sdl-2,
|
|
|
|
|
note that the 32bit version is needed.
|
|
|
|
|
|
|
|
|
|
On debian/ubuntu this could be as simple as installing the `libsdl2-dev:i386` package.
|
|
|
|
|
|
|
|
|
|
Using SDL2 requires more stack so in case you are using it add
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
CFLAGS += '-DTHREAD_STACKSIZE_MAIN=48*1024'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
to your makefile. 48kB is enough for the test, other uses may need more or may
|
|
|
|
|
need this to be applied to other threads using `THREAD_STACKSIZE_DEFAULT`
|
|
|
