 ```
+Tip:
+	此过程中还会自动创建一个软连接到 C:\Espressif\frameworks\esp-idf-v4.4 目录，方便搜索代码。
 ```
 
+### 3.5输入指令编译
 
+```bash
+idf.py.exe build			        #编译
+idf.py.exe -p COM79  flash monitor   #编译并下载同时监控日志
+idf.py.exe -p COM79  monitor		#监控日志
+```
 
+```
+Tip:
+	1.通过win+R后输入devmgmt.msc打开设备管理器确定串口端口
+	
+	2.通过在终端输入 [System.IO.Ports.SerialPort]::getportnames() 打印所有可用端口
+	
+	3.终端输入 .\lscom.ps1 打印所有可用端口
+```
