# 1. GUI引擎
|
||
|
||
   负责对接GUI开源库。包括ubuntu动态对接lvgl模拟器和开发板的lvgl库。
|
||
|
||
## 1.1. 目录
|
||
|
||
* lvgl_common
|
||
|
||
   lvgl引擎接口二次封装的公共源码，目的是把lvgl开源库的接口解耦合，避免lvgl接口兼容导致的迭代困难。
|
||
|
||
* lvgl_board
|
||
|
||
   交叉编译源码目录，含fb驱动。lvgl源码版本和模拟器一致。
|
||
|
||
* lvgl_x86
|
||
|
||
   ubuntu系统模拟器源码。
|
||
|
||
## 1.2. 编译静态链接
|
||
|
||
   根据构建脚本TARGET_PLATFORM的定义，来选择链接lvgl_x86或者lvgl_board
|
||
```
|
||
// 只有两种链接情况，分别使用gcc编译和交叉编译
|
||
if(${TARGET_PLATFORM} MATCHES ${DEFINE_LINUX}) // 第一：链接PC模拟器，此处模拟器单独编译成lvgl-x86库
|
||
# build the lvgl sumlator in linux.
|
||
include_directories(
|
||
./lvgl_common
|
||
${EXTERNAL_SOURCE_PATH}/lvglLinux-x86/lv_sim_vscode_sdl/lvgl
|
||
)
|
||
aux_source_directory(./lvgl_x86 SRC_FILES)
|
||
aux_source_directory(./lvgl_common SRC_FILES)
|
||
set(TARGET_NAME GuiEngine-lvglx86)
|
||
add_library(${TARGET_NAME} STATIC ${SRC_FILES})
|
||
target_link_libraries(${TARGET_NAME} lvgl-x86 ReturnCode Log) // 链接模拟器库
|
||
else() // 第二：链接fb驱动代码，此处驱动源码，lvgl源码编译成GuiEngine-board库
|
||
include_directories(
|
||
./lvgl_common
|
||
${EXTERNAL_SOURCE_PATH}/lvglBoard
|
||
${EXTERNAL_SOURCE_PATH}/lvglBoard/lvgl
|
||
${EXTERNAL_SOURCE_PATH}/lvglBoard/lv_drivers
|
||
)
|
||
aux_source_directory(./lvgl_board SRC_FILES)
|
||
aux_source_directory(./lvgl_common SRC_FILES)
|
||
file(GLOB_RECURSE LVGL_SRC_FILES ${EXTERNAL_SOURCE_PATH}/lvglBoard/lvgl/src/*c) // 获取lvgl源码
|
||
file(GLOB_RECURSE LVGL_DRIVERS_SRC_FILES ${EXTERNAL_SOURCE_PATH}/lvglBoard/lv_drivers/*c) // 获取驱动源码
|
||
set(TARGET_NAME GuiEngine-board)
|
||
add_library(${TARGET_NAME} STATIC ${SRC_FILES} ${LVGL_SRC_FILES} ${LVGL_DRIVERS_SRC_FILES})
|
||
target_link_libraries(${TARGET_NAME} GuiEngineAbstract ReturnCode Log)
|
||
endif()
