sensorgnome software running on a raspberry Pi 2 or 3
Disk image releases and updates are available from
http://public.sensorgnome.org/RaspberryPi2_Sensorgnome_Images
This repository tracks changes to config and other source files, using the 2017-02-24 release as the starting point.
Because git does not preserve file ownership, you should obtain these files via the updates or images available above.
DO NOT install files directly from this repo unless you know what you're doing - otherwise, you might disable your SG. The file ls-AlR.txt in this repo lists files with their correct ownership and file permissions, for those who choose to swim beyond the buoy line.
Please use this repository to report issues with the sensorgnome software on the Raspberry Pi.
- includes DC/DC converter + RPi 3 + No GPS + ethernet cable to laptop
