## 初始化树莓派系统
1. 使用Raspberry Imager.exe进行克隆操作
2. 设备选择树莓派3

4. 选择对应的tf卡
5. 点击下一步，在弹出的窗口中选择配置设置，如已配过的，则选择是

注意：在通用设置里，配置主机名很关键，这能够保证在不知道地址的情况下寻找到这台设备

在services配置里开启ssh

所有的都配置好以后，可以开始刻录镜像了

将tf卡插入树莓派后，将笔记本和树莓派都连入同一无线AP，接下来就是等待，大致在2分钟左右。
可以使用ping命令看设备是否连接：
```shell
PS C:\Users\A> ping guards-gvsun.local

## 登录树莓派
1. 使用ssh工具连入系统，默认的用户名是pi，密码是raspberry
```shell
PS C:\Users\A> ssh pi@guards-gvsun.local
The authenticity of host 'guards-gvsun.local (fe80::e7b1:842e:a47f:d7d3%14)' can't be established.
ED25519 key fingerprint is SHA256:d4lGbpI/PaB33FVWpYJB6N15GUzt0CLW0WgX4tnsdFo.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

2. 设置root密码
```shell

New password:
Retype new password:
passwd: password updated successfully
```

3. 安装所需组件
```shell
pi@guards-gvsun:~ $ sudo bash -c "$(wget -qO- http://192.168.1.139/lipinyong/python2_iot/raw/master/setup.sh)"
配置ssh
更新系统安装git
...
```
执行完后，需要检查结果：
```shell
## 检查python版本
pi@guards-gvsun:~ $ python
Python 2.7.18 (default, Sep 19 2023, 07:10:59)

>>> exit()
## 检查pip版本
pi@guards-gvsun:~ $ pip --version
pip 20.3.4 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
```
