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)
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*/
v_disp_buf_init(&disp_buf1, 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*/
disp_drv.buffer = &disp_buf; /*Assign the buffer to teh display*/
lv_disp_drv_register(&disp_drv); /*Finally register the driver*/
void disp_flush(int32_t x1, int32_t y1, int32_t x2, int32_t y2, const lv_color_t * color_p)
void my_disp_flush(lv_disp_t * disp, const lv_area_t * area, lv_color_t * color_p)
{
int32_t x, y;
for(y = y1; y <= y2; y++) {
for(x = x1; x <= x2; x++) {
sep_pixel(x, y, *color_p); /* Put a pixel to the display.*/
for(y = area->y1; y <= area->y2; y++) {
for(x = area->x1; x <= area->x2; x++) {
set_pixel(x, y, *color_p); /* Put a pixel to the display.*/
color_p++;
}
}
lv_flush_ready(); /* Tell you are ready with the flushing*/
lv_disp_flush_ready(disp); /* Tell you are ready with the flushing*/
}
```
5. Register a function which can **read an input device**. E.g. for a touch pad:
```c
lv_indev_drv_init(&indev_drv); /*Descriptor of a input device driver*/
indev_drv.type = LV_INDEV_TYPE_POINTER; /*Touch pad is a pointer-like device*/
indev_drv.read = touchpad_read; /*Set your driver function*/
indev_drv.read_cb = my_touchpad_read; /*Set your driver function*/
lv_indev_drv_register(&indev_drv); /*Finally register the driver*/

bool touchpad_read(lv_indev_data_t * data)
bool my_touchpad_read(lv_indev_t * indev, lv_indev_data_t * data)
{
static lv_coord_t last_x = 0;
static lv_coord_t last_y = 0;
