Calliope Mini Demo (And Board Test)

Calliope Mini Demo (and Board Test)

This is the original board demo code that is on Calliope mini after production. It contains the production test code, which is used to check that all components work as expected as well as the four demos you found when you switched it on.

The production test will be displayed once, after re-flashing this code. It is also an example how to use the non-volatile memory within the Calliope mini MCU.

Install yotta to compile the project or download the latest release. By default, the project will use German words in the demo. To compile for english, use the following command line to compile:

yt build --config config_en.json
