燒錄sd

所有操作以 macos 為例

需要使用 balenaEtcher 燒錄 image

brew cask install balenaetcher

# 啟動 balenaEtcher > 選擇 image (e.g. 2019-xx-xx-raspbian-buster-full.img) > select target (SD) > Flash! (等待燒錄完成)

直在 SD 卡上，設置設定 (e.g. wifi & 啟用 ssh, hdmi)

啟用 ssh

touch /Volumes/boot ssh

設置 wifi

vi /Volumes/boot/wpa_supplicant.conf

# 貼下這一段
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="wifi 的 ssid 請自行更改"
    scan_ssid=1
    priority=1
    psk="wifi的密碼"
    key_mgmt=WPA-PSK
}
# network 有多個的話，可依續填入
network={
    ssid="wifi 的 ssid 請自行更改"
    scan_ssid=1
    priority=1
    psk="wifi的密碼"
    key_mgmt=WPA-PSK
}

設定 HDMI 輸出

vi /Volumes/boot/config.txt
# uncomment 這二項，以強制使用 hdmi
hdmi_force_hotplug=1
hdmi_drive=2

SSH

# default user: pi, password: raspberry
ssh pi@內網ip

docker

sudo su
curl -sSL https://get.docker.com/ | sh

VNC

使用系统自带VNC，并且开机启动

sudo raspi-config
# 选择 Interfacing Options -> 找到VNC（远程桌面） 选择 Yes（是）enable

sudo nano /etc/init.d/vncserver
# 貼上以下這一段
#!/bin/sh
### BEGIN INIT INFO

su $USER -c '/usr/bin/vncserver -depth 16 -geometry 1024x768 :1'
echo "Starting VNC server for $USER "
;;
stop)
# 终止命令行。此处控制台号码与启动一致。
su $USER -c '/usr/bin/vncserver -kill :1'
echo "vncserver stopped"
;;
*)
echo "Usage: /etc/init.d/vncserver {start|stop}"
exit 1
;;
esac
exit 0


# 更改權限
sudo chmod 755 /etc/init.d/vncserver
# 設定開機啟動
sudo update-rc.d vncserver defaults

攝像頭(USB)

fswebcam 用于访问摄像头、进行拍照等

sudo apt-get install fswebcam 

# 拍照
fswebcam image.jpg

MJPG-streamer 是一个优秀的开源 project，它可以通过 HTTP 的方式访问 linux 上面的兼容摄像头，从而做到远程视频传输的效果。

sudo raspi-config 
# interface -> camera -> enable

sudo apt-get update sudo apt-get install subversion libjpeg8-dev imagemagick libv4l-dev cmake git -y
