leafcast plant camera backend

Leafcast - pi client rust

The pi client for Leafcast, powered by staticPi.com

Built in Rust
_{See typescript branch for original, now not maintained, TypeScript version}

See the frontend website source here

Required Hardware

1. Raspberry pi - designed for, tested, and fully working, on a Raspberry pi zero w 2
2. Pi camera, such as camera module

Required services

1. staticPi - the simple and secure messaging service

Required software

1. libcamera-still - should be pre-installed in recent Pi OS version
2. libwebp - should be pre-installed in recent Pi OS version

Download

See releases

download (aarch64 one liner)

wget https://www.github.com/mrjackwills/leafcast_pi/releases/latest/download/leafcast_linux_aarch64.tar.gz &&
tar xzvf leafcast_linux_aarch64.tar.gz leafcast

Run step

a) sudo ./leafcast -i create and install systemd service file, to automatically run on boot

or

b) ./leafcast run in current session

Suggested directories and file

directory	reason
~/leafcast/logs	Log files
~/leafcast/photos	photo storage
~/leafcast/.env	environmental variables
/ramdrive/ip.addr	ip address

# addition to /etc/fstab
ramdrive /ramdrive tmpfs defaults,noatime,size=128K     0       0

suggested crontab

@reboot ip addr show wlan0 | grep -Po 'inet \K[\d.]+' > /ramdrive/ip.addr
*/5 * * * * ip addr show wlan0 | grep -Po 'inet \K[\d.]+' > /ramdrive/ip.addr

ip address gets updated every 5 minutes, so write to a ramdrive rather than causing repetitive, eventually damaging, writes to the pi's SD card

Build step

Raspberry pi 64bit pi (pi zero 2 w, pi 4)

requires docker & cross-rs

1. cross build --target aarch64-unknown-linux-musl --release or cross build --target aarch64-unknown-linux-gnu --release

Tests

Testing is a work in progress

cargo test -- --test-threads=1
