Building and Running MicroFMU on Unix

Overview

This guide walks you through compiling and running the MicroFMU library on a Unix-based system using MicroPython.

Prerequisites

• A Unix-based system (Linux/macOS)

• Installed dependencies: gcc, make, python3, and pip

• MicroPython source code (micropython_dir set correctly)

Steps

1. Navigate to the Unix port directory

   cd "$micropython_dir/ports/unix"
   

2. Compile MicroPython with MicroFMU support

   make submodules
   make USER_C_MODULES=$micropython_dir/MicroFMU-library
   

3. Run MicroPython and test FMU simulation

   ./build-standard/micropython
   

   >>> import ufmu as fmu
   >>> simulation = fmu.setup_simulation(0, 3, 0.1)
   >>> for step, time, h, _, v, _, g, e in simulation:
   ...     print(time, h)
   

4. (Optional) Enable Debugging

   make DEBUG=1 STRIP= USER_C_MODULES=$micropython_dir/MicroFMU-library/micropython.cmake
