## RT-Thread studio添加外设的疑惑
- 工程根目录下的 Kconfig内容，所以疑惑下图这些Kconfig在哪个文件配置的？

```
mainmenu "RT-Thread Configuration"

config BSP_DIR
    string
    option env="BSP_ROOT"
    default "."

config RTT_DIR
    string
    option env="RTT_ROOT"
    default "rt-thread"

config PKGS_DIR
    string
    option env="PKGS_ROOT"
    default "packages"

source "$RTT_DIR/Kconfig"
source "$PKGS_DIR/Kconfig"
source "$PKGS_DIR/packages/misc/samples/Kconfig"

config RT_STUDIO_BUILT_IN
    bool
    select ARCH_ARM_CORTEX_M4
    select RT_USING_COMPONENTS_INIT
    select RT_USING_USER_MAIN
    default y
```
