Recommendations for choosing embedded software

When choosing between a strategy for code optimization or portability, here are some recommendations:

•

Standard Peripheral Library offers a good tradeoff for users willing to remain within the STM32 F0 series in the future, with a portability level

ensured among all STM32F3 MCUs

•

STM32CubeF3 embedded software is the correct choice for users who may want to easily port their application to another STM32 MCUs. In

addition, this option also benefits from the full features of the STM32CubeMX tool on the PC, enabling access to code generation based on

the user configuration and STM32CubeF3 embedded software

Focus on model development with MATLAB/Simulink

MATLAB and Simulink users can also benefit from the STM32F3 series with their favorite environment.

A simple 3‑step approach is possible using MATLAB and Simulink:

1. Create an algorithm model and simulate it on the host.

2. Generate Processor‑in‑the‑Loop (PIL) code and verify it. This step uses MATLAB/Simulink to generate code optimized for the Cortex®‑M4

devices using the DSP instruction set.

3. And finally, let everything run on the STM32F3 MCU using the peripheral blockset provided by ST, enabling the use of real STM32F3

peripherals such as the ADC, DAC, Timers, etc.

Model development helps reduce development time and specification errors usually found with other methods.
