業務代碼。

• BUILD.gn為編譯腳本
• led.c為業務邏輯代碼所在文件

static_library("bahuyang") {

sources = [

"led.c"

include_dirs = [

"http://utils/native/lite/include",

"http://kernel/liteos_m/components/cmsis/2.0",

"http://base/iot_hardware/interfaces/kits/wifiiot_lite",

}

• “bahuyang”:是生成靜態庫名稱，可隨意更改
• “led.c”：代碼文件

import("http://build/lite/config/component/lite_component.gni")

lite_component("app") {

features = [

#"startup",

"led:bahuyang"

}

• 將"startup"注釋，運行我們自己的文件
• “led”:工程目錄
• bahuyang:靜態庫文件

我在以前的文章里，詳細講解了怎樣編譯。大家可以回頭看看。
我們進入終端面板下，在對應工程目錄下，輸入python build.py wifiiot
進行編譯，當出現編譯成功時，就代表編譯完成。

燒錄利用HiBurn工具進行燒錄，我在以前的文章里，詳細講過。

選定文件后，點擊connect，按下開發板復位按鈕，進行燒錄。
燒錄完成后，再次按下復位按鍵。
