## v7.0.0 (18.05.2020)
### Documentation
The docs for v7 is available at https://docs.littlevgl.com/v7/en/html/index.html
### Legal changes
The name of the project is changed to LVGL and the new website is on https://lvgl.io
LVGL remains free under the same conditions (MIT license) and a company is created to manage LVGL and offer services.
### New drawing system
Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects.
A possible use-case of this system is to remove the overflowing content from the rounded edges.
It also allows drawing perfectly anti-aliased circles, lines, and arcs.
Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle).
When something is drawn the currently active masks can make some pixels transparent.
For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part.
The API in this regard remained the same but some new functions were added:
- `lv_img_set_zoom`: set image object's zoom factor
- `lv_img_set_angle`: set image object's angle without using canvas
- `lv_img_set_pivot`: set the pivot point of rotation
The new drawing engine brought new drawing features too. They are highlighted in the "style" section.
### New style system
The old style system is replaced with a new more flexible and lightweighted one.
It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object.
As part of these updates, a lot of objects were reworked and the APIs have been changed.
- more shadows options: *offset* and *spread*
- gradient stop position to shift the gradient area and horizontal gradient
- `LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE` blending modes
- *clip corner*: crop the content on the rounded corners
- *text underline* and *strikethrough*
- dashed vertical and horizontal lines (*dash gap*, *dash_width*)
- *outline*: a border-like part drawn out of the background. Can have spacing to the background.
- *pattern*: display and image in the middle of the background or repeat it
- *value* display a text which is stored in the style. It can be used e.g. as a lighweighted text on buttons too.
- *margin*: similar to *padding* but used to keep space outside of the object
Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works.
### GPU integration
To better utilize GPUs, from this version GPU usage can be integrated into LVGL. In `lv_conf.h` any supported GPUs can be enabled with a single configuration option.
Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases.
### Renames
The following object types are renamed:
- sw -> switch
- ta -> textarea
- cb -> checkbox
- lmeter -> linemeter
- mbox -> msgbox
- ddlist -> dropdown
- btnm -> btnmatrix
- kb -> keyboard
- preload -> spinner
- lv_objx folder -> lv_widgets
- LV_FIT_FILL -> LV_FIT_PARENT
- LV_FIT_FLOOD -> LV_FLOOD_MAX
- LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT
- LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM
### Reworked and improved object
- `dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right.
- `label`: `body_draw` is removed, instead, if its style has a visible background/border/shadow etc it will be drawn. Padding really makes the object larger (not just virtually as before)
- `arc`: can draw bacground too.
- `btn`: doesn't store styles for each state because it's done naturally in the new style system.
- `calendar`: highlight the pressed datum. The used styles are changed: use `LV_CALENDAR_PART_DATE` normal for normal dates, checked for highlighted, focused for today, pressed for the being pressed. (checked+pressed, focused+pressed also work)
- `chart`: only has `LINE` and `COLUMN` types because with new styles all the others can be described. LV_CHART_PART_SERIES sets the style of the series. bg_opa > 0 draws an area in LINE mode. `LV_CHART_PART_SERIES_BG` also added to set a different style for the series area. Padding in `LV_CHART_PART_BG` makes the series area smaller, and it ensures space for axis labels/numbers.
- `linemeter`, `gauge`: can have background if the related style properties are set. Padding makes the scale/lines smaller. scale_border_width and scale_end_border_width allow to draw an arc on the outer part of the scale lines.
- `gauge`: `lv_gauge_set_needle_img` allows use image as needle
- `canvas`: allow drawing to true color alpha and alpha only canvas, add `lv_canvas_blur_hor/ver` and rename `lv_canvas_rotate` to `lv_canvas_transform`
- `textarea`: If available in the font use bullet (`U+2022`) character in text area password
### New object types
- `lv_objmask`: masks can be added to it. The children will be masked accordingly.
### Others
- Change the built-in fonts to [Montserrat](https://fonts.google.com/specimen/Montserrat) and add built-in fonts from 12 px to 48 px for every 2nd size.
- Add example CJK and Arabic/Persian/Hebrew built-in font
- Add ° and "bullet" to the built-in fonts
- Add Arabic/Persian script support: change the character according to its position in the text.
- Add `playback_time` to animations.
- Add `repeat_count` to animations instead of the current "repeat forever".
- Replace `LV_LAYOUT_PRETTY` with `LV_LAYOUT_PRETTY_TOP/MID/BOTTOM`
### Demos
- [lv_examples](https://github.com/littlevgl/lv_examples) was reworked and new examples and demos were added
### New release policy
- Maintain this Changelog for every release
- Save old major version in new branches. E.g. `release/v6`
- Merge new features and fixes directly into `master` and release a patch or minor releases every 2 weeks.
### Migrating from v6 to v7
- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`.
- To try the new version it suggested using a simulator project and see the examples.
- If you have a running project, the most difficult part of the migration is updating to the new style system. Unfortunately, there is no better way than manually updating to the new format.
- The other parts are mainly minor renames and refactoring as described above.

## 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.

# Contributing to Littlev Graphics Library
# Contributing to LVGL
**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!**
Thank you for considering contributing to LVGL.
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).

# Roadmap
This is a summary for thenew fatures of the major releases and a collection of ideas.
This list indicates only the current intention and can be changed.
## v8
Planned to November/December 2020
- Create an `lv_components` repository for compley widgets
- It makes the core LVGL leaner
- In `lv_components` we can have a lot and specific widgets
- Good place for contribution
- New scrolling:
- See [feat/new-scroll](https://github.com/lvgl/lvgl/tree/feat/new-scroll) branch and [#1614](https://github.com/lvgl/lvgl/issues/1614)) issue.
- Remove `lv_page` and support scrolling on `lv_obj`
- Support "elastic" scrolling when scrolled in
- Support scroll chaining among any objects types (not only `lv_pages`s)
- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
- Add snapping
- Add snap stop to scroll max 1 snap point
- Already working
- New layouts:
- See [#1615](https://github.com/lvgl/lvgl/issues/1615) issue
- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support
- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support
- Remove `lv_cont` and support layouts on `lv_obj`
- Simplified File system interface ([feat/new_fs_api](https://github.com/lvgl/lvgl/tree/feat/new-fs-api) branch) to make porting easier
- Work in progress
- Remove the align parameter from `lv_canvas_draw_text`
- Make the copy parameter obsolate in create functions
- Optimize and simplifie styles [#1832](https://github.com/lvgl/lvgl/issues/1832)
- Use a more generic inheritenace [#1919](https://github.com/lvgl/lvgl/issues/1919)
## v8.x
- Add radio button widget
- Unit testing (gtest?). See [#1658](https://github.com/lvgl/lvgl/issues/1658)
- Benchmarking (gem5?). See [#1660](https://github.com/lvgl/lvgl/issues/1660)
- chart: pre-delete `X` pint after the lastly set
- chart: autoscroll to the right
## v9
- Simplify `group`s. Discussion is [here](https://forum.lvgl.io/t/lv-group-tabindex/2927/3).
- Consider direct binary font format support
- Optimize line and circle drawing and masking
- Reconsider color format management for run time color format setting, and custom color format usage. (Also [RGB888](https://github.com/lvgl/lvgl/issues/1722))
- 9-patch support for `lv_imgbtn`.
- Handle stride. See [#1858](https://github.com/lvgl/lvgl/issues/1858)
- Make gradients more versatile
- Make image transformations more versatile
- Allow snapshoting object to tranfrom them to images
## Ideas
- Use [generate-changelog](https://github.com/lob/generate-changelog) to automatically generate changelog
- lv_mem_alloc_aligned(size, align)
- Text node. See [#1701](https://github.com/lvgl/lvgl/issues/1701#issuecomment-699479408)
- CPP binding. See [Forum](https://forum.lvgl.io/t/is-it-possible-to-officially-support-optional-cpp-api/2736)
- Optimize font decompression
- Switch to RGBA colors in styles
- Need coverage report for tests
- Need static analyze (via coverity.io or somehing else)
- Support dot_begin and dot_middle long modes for labels
- Add new label alignment modes. [#1656](https://github.com/lvgl/lvgl/issues/1656)
- Support larger images: [#1892](https://github.com/lvgl/lvgl/issues/1892)

/**
* Macro to declare the most important style set/get API functions.
*
* Get the value of a style property from an object in the object's current state
* -----------------------------------------------------------------------------
* - Get the value of a style property from an object in the object's current state.
* - Transition animation is taken into account.
* - If the property is not set in the object's styles check the parent(s) if the property can be inherited
* - If still not found return a default value.
* - For example:
* `lv_style_int_t w = lv_obj_get_style_border_width(btn1, LV_BTN_PART_MAIN);`
*
* Set a local style property for an object in a given state
* ---------------------------------------------------------
* - For example:
* `lv_obj_set_style_local_border_width(btn1, LV_BTN_PART_MAIN, LV_STATE_PRESSED, 2);`
*
* Get a local style property's value of an object in a given state
* ----------------------------------------------------------------
* - Return the best matching property in the given state.
* - E.g. if `state` parameter is LV_STATE_PRESSED | LV_STATE_CHECKED` but the property defined only in
* `LV_STATE_PRESSED` and `LV_STATE_DEFAULT` the best matching state is `LV_STATE_PRESSED`
* (because it has higher precedence) and it will be returned.
* - If the property is not found even in `LV_STATE_DEFAULT` `-1` is returned.
* - For example:
* `//Type of result should be lv_style_int_t/lv_opa_t/lv_color_t/const void * according to the type of the property`
* `lv_style_int_t result;`
* `lv_obj_get_style_local_border_width(btn1, LV_BTN_PART_MAIN, LV_STATE_PRESSED, &result);`
* `if(weight > 0) ...the property is found and loaded into result...`
*
* Get the value from a style in a given state
* -------------------------------------------
* - The same rules applies to the return value then for "lv_obj_get_style_local_...()" above
* - For example
* `int16_t weight = lv_style_get_border_width(&style1, LV_STATE_PRESSED, &result);`
* `if(weight > 0) ...the property is found and loaded into result...`
* Set a value in a style in a given state
* ---------------------------------------
* - For example
* `lv_style_set_border_width(&style1, LV_STATE_PRESSED, 2);`
