howto start

1. download OS for orangepi 3 lts

ubuntu (preference)

armbian

2. install on emmc

https://jumptuck.com/blog/2023-02-13-install-linux-orange-pi-3-lts-emmc/

nand-sata-install

3. setup wifi

sudo nmcli dev wifi connect %yourwifissid% password '%yourwifipass%'

nmcli connection modify %yourwifissid% connection.autoconnect yes
nmcli device set wlan0 autoconnect yes

4. setup dtb overlays for spi

in /boot/orangepiEnv.txt

overlays=spi-spidev1
param_spidev_spi_bus=1
param_spidev_spi_cs=0
param_spidev_max_freq=100000000

examples with dtc and fdtdump/fdtput (to modify something):

sudo apt install device-tree-compiler
sudo fdtput sun50i-h6-orangepi-3-lts.dtb /soc/spi@5011000 status -t s "okay"
sudo fdtdump sun50i-h6-orangepi-3-lts.dtb
dtc -I dtb -O dts sun50i-h6-orangepi-3-lts.dtb

spi access

# create file: /etc/udev/rules.d/50-spi.rules
# with content:

SUBSYSTEM=="spidev", GROUP="spiuser", MODE="0660"

# next:
sudo groupadd spiuser
sudo adduser "$USER" spiuser

i2c access

# create file /etc/udev/rules.d/50-i2c.rules
# with content

SUBSYSTEM=="i2c-dev", GROUP="i2c", MODE="0660"

# next
sudo groupadd i2c
sudo adduser "$USER" i2c

gpio access

# create /etc/udev/rules.d/50-gpio.rules

SUBSYSTEM=="gpio",GROUP="gpio", MODE="0660"

sudo groupadd gpio
sudo adduser "$USER" gpio

5. install docker

sudo apt install ca-certificates curl gnupg lsb-release
# gpg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
# repo
echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
# install
sudo apt update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo usermod -aG docker $USER

6. install arduino-cli & compile code

mkdir ~/arduino-cli/bin
curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | BINDIR=~/arduino-cli/bin sh
echo 'export PATH="${HOME}/arduino-cli/bin:${PATH}"' >> ~/.bashrc

sudo apt install arduino-ctags

# fix error workaround (orpi3lts)
cd .arduino15/packages/builtin/tools/ctags/5.8-arduino11
mv ctags orig.ctags
ln -s /usr/bin/arduino-ctags ctags

arduino-cli core update-index

arduino-cli upload -p /dev/ttyUSB0 --fqbn arduino:avr:mega:cpu=atmega2560 arduino_controller

7. setup variables

8. docker-compose up

./docker/run_prod.sh

ssh forwating

ssh -L 127.0.0.1:5000:localhost:5000 [email protected] -p 9622

todo:

• fastapi_users сделать аутентификацию:
• развернуть postgress бд
• завернуть api в контейнер:
  • https://github.com/avishayp/spidev
  • hypriot/rpi-kernel#24
  • docker run --rm -it --cap-add ALL -v /lib/modules:/lib/modules -v /sys:/sys --device /dev/mem:/dev/mem --privileged --entrypoint bash ubuntu:18.04
• фоновый процесс который по расписанию работает
• логгирование информации через телеграм бота
• крутую ui для настройки всяких штук (ага щас)

• серводвигатели штука https://github.com/RobTillaart/PCA9685_RT

• еще надо разобраться с уровнем воды

sudo systemctl stop docker.socket
sudo systemctl stop containerd
sudo mkdir -p /media/data
