This cross-platform C++ library provides its consumers the ability to compile and execute Arduino sketches on a hosted environment, with bindings to its virtual I/O ports to allow the host application to interact with its child sketches.

Check our Wiki for more information about usage.

Supported I/O

• GPIO (Arduino's digitalRead, analogWrite, etc)
• UART (Arduino's Serial global)
• SD (writes to host's filesystem in a pre-configured root)
• MQTT (interface of arduino-mqtt) - Note: cannot be monitored by host application
• OV767X Camera (interface of Arduino_OV767X) - Note: available pixel formats differ

Supported sketch languages

• C++
• Arduino C++ (through arduino-prelude)
• Juniper (requires the Juniper compiler to be already installed)

Build Requirements

• CMake >= 3.16
• C++20 compiler (tested with GCC >= 10, Clang/LLVM >= 10, MSVC >= 19.28, AppleClang)
• Boost >= 1.74 - Not an interface requirement however (you only need Boost headers to build the library, not when using it precompiled)
• OpenSSL (tested with 1.1.1)

Automatically built from source

• libmosquitto 2.0.9 - Used for providing MQTT support

Runtime Requirements

• CMake >= 3.12
• C++ compiler with support for at least C++11 - MinGW and MSVC-Wine are NOT officially supported

Optional

• Ninja - On Un*x, will be used by setting CMAKE_GENERATOR (if that environment variable is unset)

Build instructions

cmake -S . -B build
cd build
cmake --build .

Running the testsuite

cmake --build . --target SMCE_Tests
ctest

Packaging

cpack

Future development

• Serve the Doxygen-generated docs
• Making a proper Hugo-generated wiki in Markdown
• std::error_codeify smce::Board
• Add more I/O features, in particular the ones that were in SMartCarEmul
• Add interrupts support
• Allow consumers to specify toolchain files
