## Usage
|
||||||
|
|
||||||
|
Edit your `Cargo.toml` file dependencies with:
|
||||||
|
```
|
||||||
|
$ cargo add lvgl
|
||||||
|
```
|
||||||
|
|
||||||
|
The build requires the environment variable bellow to be set:
|
||||||
|
|
||||||
|
- `DEP_LV_CONFIG_PATH`: Path to the directory containing the `lv_conf.h` header file used for configuration of LittlevGL library.
|
||||||
|
|
||||||
|
We recommend the `lv_conf.h` file to be in your project's root directory. If so, the command to build your project would be:
|
||||||
|
```shell script
|
||||||
|
$ DEP_LV_CONFIG_PATH=`pwd` cargo build
|
||||||
|
```

## Usage
|
||||||
|
|
||||||
|
Build requires environment variables to be set:
|
||||||
|
|
||||||
|
- `DEP_LV_CONFIG_PATH`: Path to the directory containing the `lv_conf.h` header file used for configuration of LittlevGL library.
|
||||||
|
|
||||||
|
We recommend the `lv_conf.h` file to be in your project's root directory. If so, the command to build your project would be:
|
||||||
|
```shell script
|
||||||
|
$ DEP_LV_CONFIG_PATH=`pwd` cargo build
|
||||||
|
```
