Be sure to have your environment correctly set up (see Getting Started) and ledgerblue installed.

Compilation

make DEBUG=1  # compile optionally with PRINTF
make load     # load the app on the Nano using ledgerblue

Documentation

High level documentation such as APDU, and commands are included in the developer documentation which can be generated with doxygen

doxygen .doxygen/Doxyfile

the process outputs HTML and LaTeX documentations in doc/html and doc/latex folders.

Tests & Continuous Integration

The flow processed in GitHub Actions is the following:

• Code formatting with clang-format
• Compilation of the application for Ledger Nano S in ledger-app-builder
• End-to-end tests with Speculos emulator (see tests/)

It outputs 2 artifacts:

• conflux-app-debug within output files of the compilation process in debug mode
• speculos-log within APDU command/response when executing end-to-end tests
