## Porting
In the most sime 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 ()
4. Call `lv_task_handler()` periodically in every few milliseconds

## Project set-up
1. **Clone** or download the lvgl repository: `git clone https://github.com/littlevgl/lvgl.git`
1. **Clone** or [Download](https://littlevgl.com/download) the lvgl repository: `git clone https://github.com/littlevgl/lvgl.git`
2. **Create project** with your prefered IDE and add the *lvgl* folder
3. Copy **lvgl/lv_conf_templ.h** as **lv_conf.h** next to the *lvgl* folder
4. In the *_conf.h files delete the first `#if 0` and its `#endif`. Let the default configurations at first.
4. In the lv_conf.h delete the first `#if 0` and its `#endif`. Let the default configurations at first.
5. In your *main.c*: #include "lvgl/lvgl.h"
6. In your *main function*:
* lvgl_init();
