## Porting
In the most sime case you need 4 things:
In the simplest case you need 4 things:
1. Call `lv_tick_inc(1)` in every millisecods in a Timer or Task
2. Register a function which can **copy a pixel array** to an area of the screen.
3. Register a function which can **read an input device**. (E.g. touch pad)
4. Call `lv_task_handler()` periodically in every few milliseconds

## PC Simulator
If you don't have got an embedded hardware you can test the graphics library in a PC simulator. The simulator uses [SDL2](https://www.libsdl.org/) to emulate a display on your monitor and a touch pad with your mouse.
