# Littlev Graphics Libraray
![LittlevGL cover](http://www.gl.littlev.hu/home/main_cover_small.png)
LittlevGL provides everything you need to create a Graphical User Interface (GUI) on embedded systems with easy-to-use graphical elements, beautiful visual effects and low memory footprint.
Homepage: https://littlevgl.com
### Table Of Content
* [Key features](#key-features)
* [Porting](#porting)
* [Project set-up](#project-set-up)
* [PC simulator](#pc-simulator)
* [Screenshots](#screenshots)
* [Contributing](#contributing)
* [Donate](#donate)
## Key features
* Powerful building blocks buttons, charts, lists, sliders, images etc
* Advanced graphics with animations, anti-aliasing, opacity, smooth scrolling
* Various input devices touch pad, mouse, keyboard, encoder, buttons etc
* Multi language support with UTF-8 decoding
* Fully customizable graphical elements
* Hardware independent to use with any microcontroller or display
* Scalable to operate with few memory (50 kB Flash, 10 kB RAM)
* OS, External memory and GPU supported but not required
* Single frame buffer operation even with advances graphical effects
* Written in C for maximal compatibility
* Simulator to develop on PC without embedded hardware
* Tutorials, examples, themes for rapid development
* Documentation and API references online
## 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
For more information visit https://littlevgl.com/porting
## Project set-up
1. **Clone** or [Download](https://littlevgl.com/download) the lvgl repository: `git clone https://github.com/littlevgl/lvgl.git`
2. **Create project** with your preferred 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 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();
* tick, display and input device initialization (see above)
7. To **test** create a label: `lv_obj_t * label = lv_label_create(lv_scr_act(), NULL);`
8. In the main *while(1)* call `lv_task_handler();` and make a few milliseconds delay (e.g. `my_delay_ms(5);`)
9. Compile the code and load it to your embedded hardware
## 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.
There is a pre-configured PC project for **Eclipse CDT** in this repository: https://github.com/littlevgl/pc_simulator
