業(yè)務(wù)代碼。

• BUILD.gn為編譯腳本
• hello_world.c為業(yè)務(wù)邏輯代碼所在文件

• “bahuyang”:是生成靜態(tài)庫(kù)名稱，可隨意更改
• “l(fā)ed.c”：代碼文件

我在以前的文章里，詳細(xì)講解了怎樣編譯。大家可以回頭看看。
我們進(jìn)入終端面板下，在對(duì)應(yīng)工程目錄下，輸入python build.py wifiiot
進(jìn)行編譯，當(dāng)出現(xiàn)編譯成功時(shí)，就代表編譯完成。

燒錄利用HiBurn工具進(jìn)行燒錄，我在以前的文章里，詳細(xì)講過(guò)。

選定文件后，點(diǎn)擊connect，按下開(kāi)發(fā)板復(fù)位按鈕，進(jìn)行燒錄。
燒錄完成后，再次按下復(fù)位按鍵。
觀察現(xiàn)象選擇波特率115200，連接相應(yīng)串口，觀看串口調(diào)試助手的結(jié)果。
