Orange Pi Zero2 Information

Introduction

Note: the most important and helpful resource is the manual, which is available here.

Prepare the SD card

Copy the orange pi image over to an sd card
Expand the sd card

Update netplan. Open up the sd card and modify the network config:

sudo mv orangepi-default.yaml orangepi-default.yaml.bak
cat << EOL | sudo tee 99-home.yaml

install tmux
```
sudo apt update && sudo apt install -y tmux
```
then open a new tmux window using the tmux command and upgrade your packages
(optional) install tailscale
you can use these instructions
(optional, can do later) Upgrade
```
sudo apt upgrade -y
```
use ctrl+b then d to exit and let the install run. You will need to check in periodically to intervene
(Optional) Set up orange pi config
```
sudo orangepi-config
```

Update systems

sudo adduser $USER i2c
echo "overlays=i2c3" | sudo tee -a /boot/orangepiEnv.txt && sudo reboot now

once restarted run

sudo i2cdetect -y 3

Working with I/O

you will need some prerequisites:

#required
sudo apt install -y python3-pip swig python3-dev python3-setuptools

(optional) Install WiringOP

orangepi@orangepi:~$ sudo apt update
orangepi@orangepi:~$ sudo apt install -y git
orangepi@orangepi:~$ git clone https://github.com/orangepi-xunlong/wiringOP
2) Compile and install wiringOP
orangepi@orangepi:~$ cd wiringOP
orangepi@orangepi:~/wiringOP$ sudo ./build clean
orangepi@orangepi:~/wiringOP$ sudo ./build

Install wiringop-python

git clone --recursive https://github.com/orangepi-xunlong/wiringOP-Python.git
cd wiringOP-Python
find . -type f -name "*.c" -print0 | xargs -0 sed -i 's|/dev/i2c-[0-9]|/dev/i2c-3|g'

pip3 install .
sudo pip3 install .
sudo python3 ~/wiringOP-Python/examples/orangepi-sensors/oled_ssd1306.py

to get it to run on startup,

(sudo crontab -u root -l; echo "@reboot python3 $HOME/wiringOP-Python/examples/orangepi-sensors/oled_ssd1306.py" ) | sudo crontab -u root -
