||
```
|
||

|
||
```
|
||

安装Linux支持环境SDL：未安装可能会提示找不到“SDL”相关资源
|
||
```

||
sudo apt-get install -y build-essential libsdl2-dev
|
||
```
|
||
## 1.3. 修改内容
|
||
1. 自研模块自动关联开源库并使用CMakeList.txt编译；
|
||
|
||
## 1.4. 更新
|
||
1.更新了lvgl源码版本（8.3.9）覆盖lv_sim_vscode_sdl/lvgl；

||
```
|

||
/*BMP decoder library*/
|
||
#define LV_USE_BMP 1 // Use bmp picture.
|
||
/*API for open, read, etc*/
|
||
#define LV_USE_FS_POSIX 1
|
||
#if LV_USE_FS_POSIX
|
||
#define LV_FS_POSIX_LETTER 'A' /*Set an upper cased letter on which the drive will accessible (e.g. 'A')*/
|
||
#define LV_FS_POSIX_PATH "" /*Set the working directory. File/directory paths will be appended to it.*/
|
||
#define LV_FS_POSIX_CACHE_SIZE 0 /*>0 to cache this number of bytes in lv_fs_read()*/
|
||
#endif
|
||
// ================== Added by fancy code ================== finish
|
||
```
