## 功能介绍
一不小心把比赛用的MG90S烧坏了，因为马上要交作业，只能找身边现成可用的模块。

故本次作品是基于hpm5300-evk平台，实现一个网络测速功能，主要涉及到的外接模块有ESP8266无线模组。

## RT-Thread使用情况
本作品使用到了RT-THREAD 5.0.2版

```c
 \ | /
- RT -     Thread Operating System
 / | \     5.0.2 build Sep 28 2024 23:04:18
 2006 - 2022 Copyright by RT-Thread team

```
此外用到了USART驱动、AT组件、netutils组件等。

## 硬件框架
主要通过串口连接ESP8266无线模块。从官方资料中找到UART2的串口信息。

然后PIN2PIN找到具体的针脚。

接上PB08接ESP8266的RX，PB09接ESP8266的TX。再分别接上VCC和GND。

## 软件框架
在RT-STUDIO中打开UART2，再配置ESP8266于其上。

打开netutils工具，使能iperf工具。

编译并下载到HPM5300-EVK开发板。

## 测试环境
在局域网内PC端搭建个iperf服务器，刚好手头MobaXterm支持。

## 测试效果
启动HPM5300-EVK开发板。

```c

检查功能是否齐全：

```c
msh >help
RT-Thread shell commands:

网络测试--HPM5300-EVK侧：

```c
msh />iperf -c 192.168.1.101 -p 60001
[I/iperf] Connect to iperf server successful!
[I/iperf] iperfc01: 8.2460 Mbps!
[I/iperf] iperfc01: 8.1330 Mbps!
[I/iperf] iperfc01: 8.3590 Mbps!
```
iperf服务器侧：
```c
[  4] local 192.168.1.101 port 60001 connected with 192.168.1.107 port 46731
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-60.2 sec  70.6 MBytes  8.57 Mbits/sec
```
可以知道带宽为8.57 Mbps。

## 代码地址
直接通过RT-Studio配置，无手写代码。
