Ruuvi Firmware version 3. Built on top of Nordic SDK 15, uses both Ruuvi and external repositories as submodules. Under development, please follow Ruuvi Blog for details.
Download Nordic SDK15.2 and install it one level above the project root.
Run git submodule update --init --recursive. This will search for and install the other git repositories referenced by this project.
ARMGCC is used for Jenkins builds, it's recommended to use SES for developing.
Segger Embedded Studio can be set up by following this RuuviLab Tool post.
Compile and flash the project to your board using SES. Instructions on how to use a bootloader will be added later on. The project is not yet in a useful state for any practical purpose other than learning.
Note: You should erase your board entirely in case there is a bootloader from a previous firmware.
Please let us know your thoughts on the direction and structure of the project. Does the project help you to understand how to build code on RuuviTag? Is the structure of the project sensible to you? Pull requests and GitHub issues are welcome, but new features will not be accepted at this time.
Ruuvi code is BSD-3 licensed. Submodules and external dependencies have their own licenses, which generally are BSD-compatible.
