Code generation for STM32F4 boards with Modelica device drivers

With the modeling, simulation and code generation of mixed continuous/discrete models in Modelica, a development approach becomes feasible which addresses one of the core challenges in cyber-physical systems. The aim is to achieve a simulation of the embedded system model in a physical environment model, before its deployment on real hardware. Based on the already existing support for Arduino boards, an effort has been started for supporting code-generation from Modelica models for STM32F4 boards. In this paper the concept will be explained. Basically Modelica's C-interface and the experimental low-footprint embedded code generation of OpenModelica is used for generating code for the main function. The support for the STM32F4 family is realized with the C-interface functions using the hardware abstraction layer (HAL) application programming interface (API) STM32F4CUBE from ST Microelectronics.
