/**
@defgroup pkg_lvgl LittlevGL - Open-Source Embedded GUI Library
@ingroup pkg
@brief LittlevGL package for RIOT
@see https://github.com/littlevgl/lvgl
## Configuration options
The package can be configured with using several variables. These variables can
either be passed directly to build command line or set in the application
Makefile.
### Graphical settings
- `LVGL_COLOR_DEPTH`: configure the color depth in bit of the screen (default: 16)
- `LVGL_COLOR_16_SWAP`: enable byte swap when communicating with the screen
driver (default: 1, enabled)
### Memory settings
`LVGL_MEM_SIZE`: configure the maximum memory size used by lvgl. This depends
on the number of lvgl widgets and objects used by the interface (default:
5U*1024U, 5KiB). Must be greater than 2KiB.
### Engine settings
- `LVGL_INACTIVITY_PERIOD_MS`: maximum inactivity period before going to sleep in ms.
(default: 1s)
- `LVGL_TASK_HANDLER_DELAY_US`: delay between lvgl task handle call in ms.
(default: 5ms)
- `LVGL_TASK_THREAD_PRIO`: lvgl task handler thread priority.
(default: THREAD_PRIORITY_MAIN - 1)
Example of command line for changing the max activity period to 5s:
```
LVGL_ACTIVITY_PERIOD=5000 make -C tests/pkg_lvgl
```
