## Add LittlevGL to your project
The steps below show how to setup LittlevGL on an embedded system with a display and a touchpad.
You can use the [Simulators](https://docs.littlevgl.com/en/html/get-started/pc-simulator) to get ready to use projects which can be run on your PC.
1. [Download](https://littlevgl.com/download) or [Clone](https://github.com/littlevgl/lvgl) the library
2. Copy the `lvgl` folder into your project
3. Copy `lvgl/lv_conf_template.h` as `lv_conf.h` next to the `lvgl` folder and set at least `LV_HOR_RES_MAX`, `LV_VER_RES_MAX` and `LV_COLOR_DEPTH`.
4. Include `lvgl/lvgl.h` where you need to use LittlevGL related functions.
5. 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.
6. Call `lv_init()`
7. Create a display 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*/
```
8. Implement and register a function which can **copy a pixel array** to an area of your display:
```c
lv_disp_drv_t disp_drv; /*Descriptor of a display driver*/
lv_disp_drv_init(&disp_drv); /*Basic initialization*/
disp_drv.flush_cb = my_disp_flush; /*Set your driver function*/
disp_drv.buffer = &disp_buf; /*Assign the buffer to the display*/
lv_disp_drv_register(&disp_drv); /*Finally register the driver*/
void my_disp_flush(lv_disp_t * disp, const lv_area_t * area, lv_color_t * color_p)
{
int32_t x, y;
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_disp_flush_ready(disp); /* Indicate you are ready with the flushing*/
}
```
9. Implement and 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_cb = my_touchpad_read; /*Set your driver function*/
lv_indev_drv_register(&indev_drv); /*Finally register the driver*/
bool my_touchpad_read(lv_indev_drv_t * indev_driver, lv_indev_data_t * data)
{
static lv_coord_t last_x = 0;
static lv_coord_t last_y = 0;
/*Save the state and save the pressed coordinate*/
data->state = touchpad_is_pressed() ? LV_INDEV_STATE_PR : LV_INDEV_STATE_REL;
if(data->state == LV_INDEV_STATE_PR) touchpad_get_xy(&last_x, &last_y);
/*Set the coordinates (if released use the last pressed coordinates)*/
data->point.x = last_x;
data->point.y = last_y;
return false; /*Return `false` because we are not buffering and no more data to read*/
}
```
10. 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.
## Learn the basics
### Objects (Widgets)
The graphical elements like Buttons, Labels, Sliders, Charts etc are called objects in LittelvGL. Go to [Object types](https://docs.littlevgl.com/en/html/object-types/index) to see the full list of available types.
Every object has a parent object. The child object moves with the parent and if you delete the parent the children will be deleted too. Children can be visible only on their parent.
The *screen* are the "root" parents. To get the current screen call `lv_scr_act()`.
You can create a new object with `lv_<type>_create(parent, obj_to_copy)`. It will return an `lv_obj_t *` variable which should be used as a reference to the object to set its parameters.
The first parameter is the desired *parent*, te second parameters can be an object to copy (`NULL` is unused).
For example:
```c
lv_obj_t * slider1 = lv_slider_create(lv_scr_act(), NULL);
```
To set some basic attribute `lv_obj_set_<paramters_name>(obj, <value>)` function can be used. For example:
```c
lv_obj_set_x(btn1, 30);
lv_obj_set_y(btn1, 10);
lv_obj_set_size(btn1, 200, 50);
```
The objects has type specific parameters too which can be set by `lv_<type>_set_<paramters_name>(obj, <value>)` functions. For example:
```c
lv_slider_set_value(slider1, 70, LV_ANIM_ON);
```
To see the full API visit the documentation of the object types or the related header file (e.g. `lvgl/src/lv_objx/lv_slider.h`).
### Styles
Styles can be assigned to the objects to changed their appearance. A style describes the appearance of rectangle-like objects (like a button or slider), texts, images and lines at once.
You can create a new style like this:
```c
static lv_style_t style1; /*Declare a new style. Should be `static`*/
lv_style_copy(&style1, &lv_style_plain); /*Copy a built-in style*/
style1.body.main_color = LV_COLOR_RED; /*Main color*/
style1.body.grad_color = lv_color_hex(0xffd83c) /*Gradient color (orange)*/
style1.body.radius = 3;
style1.text.color = lv_color_hex3(0x0F0) /*Label color (green)*/
style1.text.font = &lv_font_dejavu_22; /*Change font*/
...
```
To set a new style for an object use the `lv_<type>set_style(obj, LV_<TYPE>_STYLE_<NAME>, &my_style)` functions. For example:
```c
lv_slider_set_style(slider1, LV_SLIDER_STYLE_BG, &slider_bg_style);
lv_slider_set_style(slider1, LV_SLIDER_STYLE_INDIC, &slider_indic_style);
lv_slider_set_style(slider1, LV_SLIDER_STYLE_KNOB, &slider_knob_style);
```
If an object's style is `NULL` then it will inherit its parent's style. For example, the labels' style are `NULL` by default. If you place them on a button then they will use the `style.text` properties from the button's style.
Learn more in [Style overview](https://docs.littlevgl.com/en/html/overview/style) section.
### Events
Events are used to inform the user if something has happened with an object. You can assign a callback to an object which will be called if the object is clicked, released, dragged, being deleted etc. It should look like this:
```c
lv_obj_set_event_cb(btn, btn_event_cb); /*Assign a callback to the button*/
...
void btn_event_cb(lv_obj_t * btn, lv_event_t event)
{
if(event == LV_EVENT_CLICKED) {
printf("Clicked\n");
}
}
```
Learn more about the events in the [Event overview](https://docs.littlevgl.com/en/html/overview/event) section.
## Examples
### Button with label
```c
lv_obj_t * btn = lv_btn_create(lv_scr_act(), NULL); /*Add a button the current screen*/
lv_obj_set_pos(btn, 10, 10); /*Set its position*/
lv_obj_set_size(btn, 100, 50); /*Set its size*/
lv_obj_set_event_cb(btn, btn_event_cb); /*Assign a callback to the button*/
lv_obj_t * label = lv_label_create(btn, NULL); /*Add a label to the button*/
lv_label_set_text(label, "Button"); /*Set the labels text*/
...
void btn_event_cb(lv_obj_t * btn, lv_event_t event)
{
if(event == LV_EVENT_CLICKED) {
printf("Clicked\n");
}
}
```
![LittlevGL button with label example](https://docs.littlevgl.com/en/misc/simple_button_example.gif)
### Button with styles
Add styles to the previously button from the previous example
```c
static lv_style_t style_btn_rel; /*A variable to store the released style*/
lv_style_copy(&style_btn_rel, &lv_style_plain); /*Initialize from a built-in style*/
style_btn_rel.body.border.color = lv_color_hex3(0x269);
style_btn_rel.body.border.width = 1;
style_btn_rel.body.main_color = lv_color_hex3(0xADF);
style_btn_rel.body.grad_color = lv_color_hex3(0x46B);
style_btn_rel.body.shadow.width = 4;
style_btn_rel.body.shadow.type = LV_SHADOW_BOTTOM;
style_btn_rel.body.radius = LV_RADIUS_CIRCLE;
style_btn_rel.text.color = lv_color_hex3(0xDEF);
static lv_style_t style_btn_pr; /*A variable to store the pressed style*/
lv_style_copy(&style_btn_pr, &style_btn_rel); /*Initialize from the released style*/
style_btn_pr.body.border.color = lv_color_hex3(0x46B);
style_btn_pr.body.main_color = lv_color_hex3(0x8BD);
style_btn_pr.body.grad_color = lv_color_hex3(0x24A);
style_btn_pr.body.shadow.width = 2;
style_btn_pr.text.color = lv_color_hex3(0xBCD);
lv_btn_set_style(btn, LV_BTN_STYLE_REL, &style_btn_rel); /*Set the button's released style*/
lv_btn_set_style(btn, LV_BTN_STYLE_PR, &style_btn_pr); /*Set the button's pressed style*/
```
![Stylsd button is LittelvGL](https://docs.littlevgl.com/en/misc/button_style_example.gif)
### Slider and object alignment
```c
lv_obj_t * label;
...
/* Create a slider in the center of the display */
lv_obj_t * slider = lv_slider_create(lv_scr_act(), NULL);
lv_obj_set_width(slider, 200); /*Set the width*/
lv_obj_align(slider, NULL, LV_ALIGN_CENTER, 0, 0); /*Align to the center of the parent (screen)*/
lv_obj_set_event_cb(slider, slider_event_cb); /*Assign an event function*/
/* Create a label below the slider */
label = lv_label_create(lv_scr_act(), NULL);
lv_label_set_text(label, "0");
lv_obj_set_auto_realign(slider, true);
lv_obj_align(label, slider, LV_ALIGN_OUT_BOTTOM_MID, 0, 10);
...
void slider_event_cb(lv_obj_t * slider, lv_event_t event)
{
if(event == LV_EVENT_VALUE_CHANGED) {
static char buf[4]; /* max 3 bytes for number plus 1 null terminating byte */
snprintf(buf, 4, "%u", lv_slider_get_value(slider));
lv_label_set_text(slider_label, buf); /*Refresh the text*/
}
}
```
![Slider example with LittlevGL](https://docs.littlevgl.com/en/misc/slider_example.gif)
### List and themes
```c
/*Texts of the list elements*/
const char * txts[] = {"First", "Second", "Third", "Forth", "Fifth", "Sixth", NULL};
/* Initialize and set a theme. `LV_THEME_NIGHT` needs to enabled in lv_conf.h. */
lv_theme_t * th = lv_theme_night_init(20, NULL);
lv_theme_set_current(th);
/*Create a list*/
lv_obj_t* list = lv_list_create(lv_scr_act(), NULL);
lv_obj_set_size(list, 120, 180);
lv_obj_set_pos(list, 10, 10);
/*Add buttons*/
uint8_t i;
for(i = 0; txts[i]; i++) {
lv_obj_t * btn = lv_list_add_btn(list, LV_SYMBOL_FILE, txts[i]);
lv_obj_set_event_cb(btn, list_event); /*Assign event function*/
lv_btn_set_toggle(btn, true); /*Enable on/off states*/
}
/* Initialize and set an other theme. `LV_THEME_MATERIAL` needs to enabled in lv_conf.h.
* If `LV_TEHE_LIVE_UPDATE 1` then the previous list's style will be updated too.*/
th = lv_theme_material_init(210, NULL);
lv_theme_set_current(th);
/*Create an other list*/
list = lv_list_create(lv_scr_act(), NULL);
lv_obj_set_size(list, 120, 180);
lv_obj_set_pos(list, 150, 10);
/*Add buttons with the same texts*/
for(i = 0; txts[i]; i++) {
lv_obj_t * btn = lv_list_add_btn(list, LV_SYMBOL_FILE, txts[i]);
lv_obj_set_event_cb(btn, list_event);
lv_btn_set_toggle(btn, true);
}

## Naming conventions
* Words are separated by '_'
* In variable and function names use only lower case letters (e.g. *height_tmp*)
* In enums and defines use only upper case letters (e.g. *e.g. MAX_LINE_NUM*)
* Global names (API):
* starts with *lv*
* followed by module name: *btn*, *label*, *style* etc.
* followed by the action (for functions): *set*, *get*, *refr* etc.
* closed with the subject: *name*, *size*, *state* etc.
* Typedefs
* prefer `typedef struct` and `typedef enum` instead of `struct name` and `enum name`
* always end `typedef struct` and `typedef enum` type names with `_t`
* Abbreviations:
* Use abbreviations on public names only if they become longer than 32 characters
* Use only very straightforward (e.g. pos: position) or well-established (e.g. pr: press) abbreviations
## Coding guide
* Functions:
* Try to write function shorter than is 50 lines
* Always shorter than 100 lines (except very straightforwards)
* Variables:
* One line, one declaration (BAD: char x, y;)
* Use `<stdint.h>` (*uint8_t*, *int32_t* etc)
* Declare variables when needed (not all at function start)
* Use the smallest required scope
* Variables in a file (outside functions) are always *static*
* Do not use global variables (use functions to set/get static variables)
## Comments
Before every function have a comment like this:
```c
/**
* Return with the screen of an object
* @param obj pointer to an object
* @return pointer to a screen
*/
lv_obj_t * lv_obj_get_scr(lv_obj_t * obj);
```
Always use `/* Something */` format and NOT `//Something`
Write readable code to avoid descriptive comments like:
`x++; /* Add 1 to x */`.
The code should show clearly what you are doing.
You should write **why** have you done this:
`x++; /*Because of closing '\0' of the string */`
Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
In comments use \` \` when referring to a variable. E.g. ``/*Update the value of `x_act`*/``
### Formatting
Here is example to show bracket placing and using of white spaces:
```c
/**
* Set a new text for a label. Memory will be allocated to store the text by the label.
* @param label pointer to a label object
* @param text '\0' terminated character string. NULL to refresh with the current text.
*/
void lv_label_set_text(lv_obj_t * label, const char * text)
{ /* Main brackets of functions in new line*/
if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
lv_obj_inv(label);
lv_label_ext_t * ext = lv_obj_get_ext(label);
/*Comment before a section */
if(text == ext->txt || text == NULL) { /*Bracket of statements start inline*/
lv_label_refr_text(label);
return;
}
...
}
```
Use 4 spaces indentation instead of tab.
You can use **astyle** to format the code. The required config flies are: `docs/astyle_c` and `docs/astyle_h`.
To format the source files:
`$ find . -type f -name "*.c" | xargs astyle --options=docs/astyle_c`
To format the header files:
`$ find . -type f -name "*.h" | xargs astyle --options=docs/astyle_h`
Append `-n` to the end to skip creation of backup file OR use `$ find . -type f -name "*.bak" -delete` (for source file's backups) and `find . -type f -name "*.orig" -delete` (for header file's backups)

# Contributing to Littlev Graphics Library
**Do you have some free time to spend with programming?
Are you working on an Embedded GUI project with LittlevGL?
See how can you help to improve the graphics library!**
There are many ways to join the community. If you have some time to work with us I'm sure you will find something that fits you! You can:
- help others in the [Forum](https://forum.littlevgl.com/)
- improve and/or translate the documentation
- write a blog post about your experiences
- report and/or fix bugs
- suggest and/or implement new features
But first, start with the most Frequently Asked Questions.
# FAQ about contributing
## Where can I write my question and remarks?
We use the [Forum](https://forum.littlevgl.com/) to ask and answer questions and [GitHub's issue tracker](https://github.com/littlevgl/lvgl/issues) for development-related discussion.
But there are some simple rules:
- Be kind and friendly.
- Speak about one thing in one issue/topic.
- Give feedback and close the issue or mark the topic as solved if your question is answered.
- Tell what you experience or expect. _"The button is not working"_ is not enough info to get help.
- If possible send an absolute minimal code example in order to reproduce the issue
- Use [Markdown](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet) to format your post.
## How can I send fixes and improvements?
Merging new code happens via Pull Requests. If you are still not familiar with the Pull Requests (PR for short) here is a quick guide:
1. **Fork** the [lvgl repository](https://github.com/littlevgl/lvgl). To do this click the "Fork" button in the top right corner. It will "copy" the `lvgl` repository to your GitHub account (`https://github.com/your_name?tab=repositories`)
2. **Clone** the forked repository and add your changes
3. **Create a PR** on GitHub from the page of your `lvgl` repository (`https://github.com/your_name/lvgl`) by hitting the "New pull request" button
4. **Set the base branch**. It means where you want to merge your update. Fixes go to `master`, new features to the actual `dev-x.y` branch.
5. **Describe** what is in the update. An example code is welcome if applicable.
Some advice:
- If you are not sure about your fix or feature it's better to open an issue first and discuss the details there.
- Maybe your fix or update won't be perfect at first. Don't be afraid, just improve it and push the new commits. The PR will be updated accordingly.
- If your update needs some extra work it's okay to say: _"I'm busy now and I will improve it soon"_ or _"Sorry, I don't have time to improve it, I hope it helps in this form too"_.
So it's better to say don't have time to continue than saying nothing.
- Please read and follow this [guide about the coding style](https://github.com/littlevgl/lvgl/blob/master/docs/CODING_STYLE.md)
## Where is the documentation?
You can read the documentation here: <https://docs.littlevgl.com/>
You can edit the documentation here: <https://github.com/littlevgl/doc>
## Where is the blog?
You can read the blog here: <https://blog.littlevgl.com/>
You can edit the blog here: <https://github.com/littlevgl/blog>
# So how and where can you contribute?
## Help others in the Forum
It's a great way to contribute to the library if you already use it.
Just go to [https://forum.littlevgl.com/](https://forum.littlevgl.com/) a register (Google and GitHub login also works).
Log in, read the titles and if you are already familiar with a topic, don't be shy, and write your suggestion.
## Improving and/or translating the documentation
If you would like to contribute to LittlevGL the documentation is the best place to start.
### Fix typos, add missing parts
If you find a typo, an obscure sentence or something which is not explained well enough in the [English documentation](https://docs.littlevgl.com/en/html/index.html)
click the *"Edit on GitHub"* button in the top right corner and fix the issue by sending a Pull Request.
### Translate the documentation
If you have time and interest you can translate the documentation to your native language or any language you speak.
You can join others to work on an already existing language or you can start a new one.
To translate the documentation we use [Zanata](https://zanata.org) which is an online translation platform.
You will find the LittlevGL project here: [LittlevGL on Zanata](https://translate.zanata.org/iteration/view/littlevgl-docs/v6.0-doc1?dswid=3430)
To get started you need to:
- register at [Zanata](https://zanata.org) which is an online translation platform.
- comment to [this post](https://forum.littlevgl.com/t/translate-the-documentation/238?u=kisvegabor)
- tell your username at *Zanata* and your selected language(s) to get permission the edit the translations
Note that a translation will be added to the documentation only if at least the [Porting section](https://docs.littlevgl.com/en/html/porting/index.html) is translated.
## Writing a blog post about your experiences
Have you ported LittlevGL to a new platform? Have you created a fancy GUI? Do you know a great trick?
You can share your knowledge on LittlevGL's blog! It's super easy to add your own post:
- Fork and clone the [blog repository](https://github.com/littlevgl/blog)
- Add your post in Markdown to the `_posts` folder.
- Store the images and other resources in a dedicated folder in `assets`
- Create a Pull Request
The blog uses [Jekyll](https://jekyllrb.com/) to convert the `.md` files to a webpage. You can easily [run Jekyll offline](https://jekyllrb.com/docs/) to check your post before creating the Pull request
## Reporting and/or fixing bugs
For simple bugfixes (typos, missing error handling, fixing a warning) is fine to send a Pull request directly. However, for more complex bugs it's better to open an issue first. In the issue, you should describe how to reproduce the bug and even add the minimal code snippet.
## Suggesting and/or implementing new features
If you have a good idea don't hesitate to share with us. It's even better if you have time to deal with its implementation. Don't be afraid if you still don't know LittlevGL well enough. We will help you to get started.
During the implementation don't forget the [Code style guide](https://github.com/littlevgl/lvgl/blob/master/docs/CODING_STYLE.md).
# Summary
I hope you have taken a liking to contribute to LittlevGL. A helpful and friendly community is waiting for you! :)
