Installation 🛠️

This section explains how to acquire the source, build the library and verify that everything works.

Prerequisites

• C++11 compatible compiler (e.g. g++, clang++)
• make build tool

For embedded targets, ensure your toolchain is configured to compile standard C++ code and provides access to an I²C implementation. Any modern GCC or Clang toolchain should suffice.

Cloning the Repository

git clone https://github.com/N3b3x/hf-pcal95555-driver.git
cd hf-pcal95555-driver

Building the Static Library

A simple Makefile is included:

make          # builds build/libpcal95555.a

The output libpcal95555.a can be linked into your application.

Using CMake

Projects that rely on CMake can add the library directly using add_subdirectory:

add_subdirectory(pcal95555)
target_link_libraries(my_app PRIVATE pcal95555)

This makes the headers available and links the static library to your target.

Running Unit Tests

The library ships with a mock-based unit test suite. Run:

make test
build/test    # executes the test binary

You should see All tests passed.

Continue with the Quick Start once the build succeeds.
