# Quantum Painter LVGL Integration :id=lvgl |
||||
|
||||
LVGL (Light and Versatile Graphics Library) is an open-source graphics library providing everything you need to create an embedded GUI for your board with easy-to-use graphical elements. |
||||
|
||||
LVGL integrates with [Quantum Painter's](quantum_painter.md) API and drivers to render to the display, the hardware supported by Quantum Painter is also supported by LVGL. |
||||
|
||||
?> Keep in mind that enabling the LVGL integration has a big impact in firmware size, it is recommeded to use a supported MCU with >256 kB of flash space. |
||||
|
||||
To learn more about LVGL and how to use it please take a look at their [official documentation](https://docs.lvgl.io/8.2/intro/) |
||||
|
||||
## Enabling LVGL :id=lvgl-enabling |
||||
To enable LVGL to be built into your firmware, add the following to `rules.mk`: |
||||
|
||||
```make |
||||
QUANTUM_PAINTER_ENABLE = yes |
||||
QUANTUM_PAINTER_DRIVERS = ...... |
||||
QUANTUM_PAINTER_LVGL_INTEGRATION = yes |
||||
``` |
||||
To configure the Quantum Painter Display Drivers please read the [Quantum Painter Display Drivers](quantum_painter.md#quantum-painter-drivers) section. |
||||
|
||||
## Quantum Painter LVGL API :id=lvgl-api |
||||
|
||||
### Quantum Painter LVGL Attach :id=lvgl-api-init |
||||
|
||||
```c |
||||
bool qp_lvgl_attach(painter_device_t device); |
||||
``` |
||||
|
||||
The `qp_lvgl_attach` function is used to set up LVGL with the supplied display, and requires an already configured display. |
||||
|
||||
```c |
||||
static painter_device_t display; |
||||
void keyboard_post_init_kb(void) { |
||||
display = qp_make_.......; // Create the display |
||||
qp_init(display, QP_ROTATION_0); // Initialise the display |
||||
|
||||
if (qp_lvgl_attach(display)) { // Attach LVGL to the display |
||||
...Your code to draw // Run LVGL specific code to draw |
||||
} |
||||
} |
||||
``` |
||||
To init. the display please read the [Display Initialisation](quantum_painter.md#quantum-painter-api-init) section. |
||||
|
||||
!> Attaching LVGL to a display means LVGL subsequently "owns" the display. Using standard Quantum Painter drawing operations with the display after LVGL attachment will likely result in display artifacts. |
||||
### Quantum Painter LVGL Detach :id=lvgl-api-init |
||||
|
||||
```c |
||||
void qp_lvgl_detach() |
||||
``` |
||||
|
||||
The `qp_lvgl_detach` function stops the internal LVGL ticks and releases resources related to it. |
||||
|
||||
## Enabling/Disabling LVGL features :id=lvgl-configuring |
||||
|
||||
You can overwrite LVGL specific features in your `lv_conf.h` file. |
