1. Copy `lv_conf_templ.h` as `lv_conf.h` next to `lvgl` and set at least `LV_HOR_RES`, `LV_VER_RES` and `LV_COLOR_DEPTH`.
2. Call `lv_tick_inc(x)` every `x` milliseconds **in a Timer or Task** (`x` should be between 1 and 10). It is required for the internal timing of LittlevGL. **It's very important that you don't call `lv_task_handler` in the same loop.**
3. Call `lv_init()`
4. Register a function which can **copy a pixel array** to an area of the screen:
4. Create a buffer for LittlevGL
```c
static lv_disp_buf_t disp_buf;
static lv_color_t buf[LV_HOR_RES_MAX * 10]; /*Declare a buffer for 10 lines*/
lv_disp_buf_init(&disp_buf, buf, NULL, LV_HOR_RES_MAX * 10); /*Initialize the display buffer*/
```
4. Implement and register a function which can **copy a pixel array** to an area of your diplay:
```c
lv_disp_drv_t disp_drv; /*Descriptor of a display driver*/
lv_disp_drv_init(&disp_drv); /*Basic initialization*/
disp_drv.disp_flush = disp_flush; /*Set your driver function*/
disp_drv.hor_res = 480; /*Set the horizontal resolution*/
disp_drv.ver_res = 320; /*Set the vertical resolution*/
disp_drv.flush_cb = my_disp_flush; /*Set your driver function*/

6. Call `lv_task_handler()` periodically every few milliseconds in the main `while(1)` loop, in Timer interrupt or in an Operation system task. It will redraw the screen if required, handle input devices etc. **It's very important that you don't call `lv_tick_inc` in the same loop.**
