一、硬件连接

1. 扩展面包板连接

2. 系统盘设置

在电脑上打开系统盘上的config.txt

在文件最后加内容:

设置项:

打开串口

enable_uart=1

保存

3. 连接串口-USB转接板

在电脑安装串口-USB转接板的驱动。
把串口-USB转接板插到电脑,并在设备管理器找到相应的串口:

这里显示是COM3

打开串口工具,并设置,启动树莓派:

这时可以使用串口来登陆树莓派了。

如果使用Putty可以类似Xshell方式远程登陆。

二、启动vnc

输入命令:

raspi-config

在选项: Interfacing Options里,打开VNC

安装并打开windows系统的VNC-View-windows

三、树莓派4B python3.7一些配置

1. 安装pip3

sudo apt-get install python-dev libatlas-base-dev
sudo apt-get install python3-distutils
# 安装pip3
sudo apt install python3-pip
# 安装numpy
wget https://www.piwheels/simple/numpy/numpy-1.17.2-cp37-cp37m-linux_armv7l.whl
sudo pip3 install numpy-1.17.2-cp37-cp37m-linux_armv7l.whl
# 安装tensorflow
# https://github/lhelontra/tensorflow-on-arm/releases/tag/v1.14.0-buster
# 下载 tensorflow-1.14.0-cp37-none-linux_armv7l.whl
sudo pip3 install tensorflow-1.14.0-cp37-none-linux_armv7l.whl
# 更换python源
cp /etc/apt/sources.list ~
cp /etc/apt/sources.d/raspi.list ~
vi /etc/apt/sources.list

更改内容为:

deb http://mirrors.ustc.edu/raspbian/raspbian/ stretch main contrib non-free rpi
sudo apt-get update
sudo apt-get upgrade

2. pip更换为国内源

sudo vim /etc/pip.conf

添加:

index-url = https://mirrors.aliyun/pypi/simple

安装PIL

sudo apt-get install libopenjp2-7
sudo pip3 install Pillow -y

安装libtiff5

sudo apt-get install libtiff5

升级wiringpi

cd /tmp
wget https://project-downloads.drogon/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb

3. 安装ffmpeg开发库

apt-get install libx264-dev libavcodec-dev libavdevice-dev libavfilter-dev libavformat-dev libavutil-dev libpostproc-dev libswresample-dev 和libswscale-dev

4. 安装opencv开发库

sudo apt-get install libopencv-dev -y
sudo apt-get install python-opencv -y

四、 OrangePi one使用Armbian更换国内源

注意原来的文件要备份,换源有时会导致部分软件安装不上

1. 换中科大源

vim /etc/apt/sources.list

内容:

deb http://mirrors.ustc.edu/ubuntu-ports/ bionic main multiverse restricted universe
deb http://mirrors.ustc.edu/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb http://mirrors.ustc.edu/ubuntu-ports/ bionic-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu/ubuntu-ports/ bionic-security main multiverse restricted universe
deb http://mirrors.ustc.edu/ubuntu-ports/ bionic-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu/ubuntu-ports/ bionic main multiverse restricted universe
deb-src http://mirrors.ustc.edu/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu/ubuntu-ports/ bionic-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu/ubuntu-ports/ bionic-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu/ubuntu-ports/ bionic-updates main multiverse

sudo apt-get update

2. 换阿里源

vim /etc/apt/sources.list
deb https://mirrors.aliyun/raspbian/raspbian/ buster main non-free contrib
deb-src https://mirrors.aliyun/raspbian/raspbian/ buster main non-free contrib
vim /etc/apt/sources.list.d/raspi.list
deb http://mirrors.tuna.tsinghua.edu/raspberrypi/ buster main ui

sudo apt-get update
sudo apt-get upgrade

3. 问题处理:

Reading package lists... Done
