# Littlev Graphics Libraray  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 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 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 ## Screenshots     ## Contributing See [CONTRIBUTING.md](https://github.com/littlevgl/lvgl/blob/master/docs/CONTRIBUTING.md) ## Donate If you are pleased with the graphics library, found it useful or be happy with the support you got, please help its further development: [](https://littlevgl.com/donate)
