prusa-connect-pi-camera

dependencies

A Raspberry Pi with a camera, where rpicam-still -n -o test.jpg just works.

Instructions

1. Add a 3rd party camera in Prusa Connect, copy the token, and set it as a CONNECT_TOKEN environment variable on your pi
2. Download and run the binary (see below instructions to setup a service)
3. Print something, pictures will be taken on an interval (5m is the default, set CONNECT_INTERVAL to override)
4. Observe the first and last images via the Print History from Prusa Connect

Run the binary as a service

Setup a service in /etc/systemd/system/prusa-connect-pi-camera.service like so:

[Unit]
Description=Prusa Connect Pi Camera Service
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=your_user
WorkingDirectory=/home/your_user
ExecStart=/usr/local/bin/prusa-connect-pi-camera
Restart=on-failure
RestartSec=10
StandardOutput=syslog
StandardError=syslog
EnvironmentFile=/etc/prusa-connect-pi-camera/config.env

[Install]
WantedBy=multi-user.target

Create a file containing environment variables in /etc/prusa-connect-pi-camera/config.env:

CONNECT_TOKEN=your_token
#CONNECT_INTERVAL=1m
#CONNECT_URL=some_other_url # Set to override the default url
#ENABLE_PPROF=true # Enable pprof for debugging if needed
#PPROF_PORT=6060 # Set port if you want other than 6060 for pprof
#CONNECT_DEBUG=true # Set debug to troubleshoot API calls

Setup and inspect the service:

sudo systemctl daemon-reload
sudo systemctl enable prusa-connect-pi-camera.service
sudo systemctl start prusa-connect-pi-camera.service
sudo systemctl status prusa-connect-pi-camera.service
sudo journalctl -u prusa-connect-pi-camera.service

Example

Here you can see the image visible in Prusa Connect.

development

generate an API client using docker

Reference

sudo docker run --rm   -v ${PWD}:/local openapitools/openapi-generator-cli generate   -i /local/specs/prusaconnect.0.22.0.yaml   -g go   -o /local/pkg/openapi

replacing the go.mod entry with the generated client

go mod edit -replace github.com/kylos101/prusa-connect-pi-camera/v2/pkg/openapi=./pkg/openapi

creating a manual release

Prior to doing, you must have set a GITHUB_TOKEN environment variable.

sudo docker run --rm --privileged   -v $PWD:/go/src/github.com/kylos101/prusa-connect-pi-camera -v /var/run/docker.sock:/var/run/docker.sock -w /go/src/github.com/kylos101/prusa-connect-pi-camera -e GITHUB_TOKEN goreleaser/goreleaser release
