linux-wire

linux-wire is a minimal Linux-native I2C abstraction that mirrors Arduino's Wire API. It ships a tiny C shim over /dev/i2c-* plus a TwoWire C++ class so Arduino-style sketches can run on Raspberry Pi-class systems without heavyweight dependencies.

Quick Start

cmake -S . -B build -DBUILD_TESTING=ON
cmake --build build
ctest --test-dir build --output-on-failure

Use cmake --install build to install headers and the static library; downstream CMake projects can simply find_package(linux_wire CONFIG REQUIRED) and link against linux_wire::linux_wire.

Example binaries (i2c_scanner, master_reader, master_writer, master_multiplier) live under build/ after compiling.
