Repository Content

software/:

• examples/: Examples for all supported languages
• build/: Compiled files
• src/: Source code of firmware
• Makefile: Makefile to build project

hardware/:

• Contains KiCad project files and additionally schematics as PDF

datasheets/:

• Contains datasheets for sensors and complex ICs that are used

Hardware

The hardware is designed with the open source EDA Suite KiCad (http://www.kicad.org). Before you are able to open the files, you have to install the Tinkerforge kicad-libraries (https://github.com/Tinkerforge/kicad-libraries). You can either clone them directly in hardware/ or clone them in a separate folder and symlink them into hardware/ (ln -s kicad_path/kicad-libraries project_path/hardware). After that you can open the .pro file in hardware/ with KiCad and from there view and modify the schematics and the PCB layout.

Software

See README.txt in the software folder for details.
